ControlLogix IO ModulesThe ControlLogix architecture provides a wide range of input and output modules to span many applications from high-speed digital to process control The ControlLogix architecture uses a ProducerConsumer model so that input information and output status can be shared among multiple controllers
Each ControlLogix IO module mounts in a ControlLogix chassis and requires a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all field-side wiring RTBs and IFMs are not included with the IO modules They must be ordered separately

AccessoriesmdashIO Modules
1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

ControlLogix IO ModulesThe ControlLogix architecture provides a wide range of input and output modules to span many applications from high-speed digital to process control The ControlLogix architecture uses a ProducerConsumer model so that input information and output status can be shared among multiple controllers
Each ControlLogix IO module mounts in a ControlLogix chassis and requires a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all field-side wiring RTBs and IFMs are not included with the IO modules They must be ordered separately

AccessoriesmdashIO Modules
1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

ControlLogix IO ModulesThe ControlLogix architecture provides a wide range of input and output modules to span many applications from high-speed digital to process control The ControlLogix architecture uses a ProducerConsumer model so that input information and output status can be shared among multiple controllers
Each ControlLogix IO module mounts in a ControlLogix chassis and requires a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all field-side wiring RTBs and IFMs are not included with the IO modules They must be ordered separately

AccessoriesmdashIO Modules
1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

Example ConfigurationmdashRedundant IO System
The 1715 redundant IO system lets a ControlLogix 5570 controller communicate to a remote redundant IO chassis over an EtherNetIP network The 1715 redundant IO system provides fault tolerance and redundancy for critical processes by using a redundant adapter pair and redundant IO module pairs
The redundant IO system must be connected to a ControlLogix 5570 system via an EtherNetIP network All connections are established via the Ethernet network by using the topologies that the 1756-EN2TR communication bridge supports

ControlLogix IO ModulesThe ControlLogix architecture provides a wide range of input and output modules to span many applications from high-speed digital to process control The ControlLogix architecture uses a ProducerConsumer model so that input information and output status can be shared among multiple controllers
Each ControlLogix IO module mounts in a ControlLogix chassis and requires a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all field-side wiring RTBs and IFMs are not included with the IO modules They must be ordered separately

1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

GuardLogix Controllers
A GuardLogix controller is a ControlLogix controller that also provides safety control
During development safety and standard have the same rules multiple programmers online editing and forcing are all allowed Once the safety system is validated and the safety signature applied safety memory is protected the safety logic cannot be modified and all safety functions operate with SIL integrity If the safety partner is present the safety integrity will be SIL3 If no safety partner is present the safety integrity will be SIL2 On the standard side of the GuardLogix controller all functions operate like a regular Logix controller
With the introduction of the GuardLogix 5580 controller you can achieve up to SIL 2PLd (Category 3) with one controller and the use of the safety task and safety IO You must use a primary controller and a safety partner to achieve SIL 3PLe (Category 4)
Use Guard IOtrade modules for field device connectivity on Ethernet or DeviceNet networks and for safety interlocking between GuardLogix controllers use Ethernet or ControlNet networks Multiple GuardLogix controllers can share safety data for zone to zone interlocking or one GuardLogix controller can use distributed safety IO between different cellsareas
The GuardLogix controller has the standard features of a ControlLogix controller and these safety-related features

Example ConfigurationmdashRedundant IO System
The 1715 redundant IO system lets a ControlLogix 5570 controller communicate to a remote redundant IO chassis over an EtherNetIP network The 1715 redundant IO system provides fault tolerance and redundancy for critical processes by using a redundant adapter pair and redundant IO module pairs
The redundant IO system must be connected to a ControlLogix 5570 system via an EtherNetIP network All connections are established via the Ethernet network by using the topologies that the 1756-EN2TR communication bridge supports

ControlLogix IO ModulesThe ControlLogix architecture provides a wide range of input and output modules to span many applications from high-speed digital to process control The ControlLogix architecture uses a ProducerConsumer model so that input information and output status can be shared among multiple controllers
Each ControlLogix IO module mounts in a ControlLogix chassis and requires a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all field-side wiring RTBs and IFMs are not included with the IO modules They must be ordered separately

1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

GuardLogix Controllers
A GuardLogix controller is a ControlLogix controller that also provides safety control
During development safety and standard have the same rules multiple programmers online editing and forcing are all allowed Once the safety system is validated and the safety signature applied safety memory is protected the safety logic cannot be modified and all safety functions operate with SIL integrity If the safety partner is present the safety integrity will be SIL3 If no safety partner is present the safety integrity will be SIL2 On the standard side of the GuardLogix controller all functions operate like a regular Logix controller
With the introduction of the GuardLogix 5580 controller you can achieve up to SIL 2PLd (Category 3) with one controller and the use of the safety task and safety IO You must use a primary controller and a safety partner to achieve SIL 3PLe (Category 4)
Use Guard IOtrade modules for field device connectivity on Ethernet or DeviceNet networks and for safety interlocking between GuardLogix controllers use Ethernet or ControlNet networks Multiple GuardLogix controllers can share safety data for zone to zone interlocking or one GuardLogix controller can use distributed safety IO between different cellsareas
The GuardLogix controller has the standard features of a ControlLogix controller and these safety-related features
Application Description
Up to SIL 3 The GuardLogix controller system is type-approved and certified for use in safety applications up to and including SIL 3 according to IEC 61508 and applications up to and including PLeCat4 according to ISO 13849-1 For more information see the followingbull GuardLogix 5570 Controllers User Manual publication 1756-UM022 Provides information on how to install configure and operate

ControlLogix IO ModulesThe ControlLogix architecture provides a wide range of input and output modules to span many applications from high-speed digital to process control The ControlLogix architecture uses a ProducerConsumer model so that input information and output status can be shared among multiple controllers
Each ControlLogix IO module mounts in a ControlLogix chassis and requires a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all field-side wiring RTBs and IFMs are not included with the IO modules They must be ordered separately

AccessoriesmdashIO Modules
1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

ControlLogix IO ModulesThe ControlLogix architecture provides a wide range of input and output modules to span many applications from high-speed digital to process control The ControlLogix architecture uses a ProducerConsumer model so that input information and output status can be shared among multiple controllers
Each ControlLogix IO module mounts in a ControlLogix chassis and requires a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all field-side wiring RTBs and IFMs are not included with the IO modules They must be ordered separately

1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

GuardLogix Controllers
A GuardLogix controller is a ControlLogix controller that also provides safety control
During development safety and standard have the same rules multiple programmers online editing and forcing are all allowed Once the safety system is validated and the safety signature applied safety memory is protected the safety logic cannot be modified and all safety functions operate with SIL integrity If the safety partner is present the safety integrity will be SIL3 If no safety partner is present the safety integrity will be SIL2 On the standard side of the GuardLogix controller all functions operate like a regular Logix controller
With the introduction of the GuardLogix 5580 controller you can achieve up to SIL 2PLd (Category 3) with one controller and the use of the safety task and safety IO You must use a primary controller and a safety partner to achieve SIL 3PLe (Category 4)
Use Guard IOtrade modules for field device connectivity on Ethernet or DeviceNet networks and for safety interlocking between GuardLogix controllers use Ethernet or ControlNet networks Multiple GuardLogix controllers can share safety data for zone to zone interlocking or one GuardLogix controller can use distributed safety IO between different cellsareas
The GuardLogix controller has the standard features of a ControlLogix controller and these safety-related features
Application Description

ControlLogix IO ModulesThe ControlLogix architecture provides a wide range of input and output modules to span many applications from high-speed digital to process control The ControlLogix architecture uses a ProducerConsumer model so that input information and output status can be shared among multiple controllers
Each ControlLogix IO module mounts in a ControlLogix chassis and requires a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all field-side wiring RTBs and IFMs are not included with the IO modules They must be ordered separately

AccessoriesmdashIO Modules
1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

ControlLogix IO ModulesThe ControlLogix architecture provides a wide range of input and output modules to span many applications from high-speed digital to process control The ControlLogix architecture uses a ProducerConsumer model so that input information and output status can be shared among multiple controllers
Each ControlLogix IO module mounts in a ControlLogix chassis and requires a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all field-side wiring RTBs and IFMs are not included with the IO modules They must be ordered separately

1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

GuardLogix Controllers
A GuardLogix controller is a ControlLogix controller that also provides safety control
During development safety and standard have the same rules multiple programmers online editing and forcing are all allowed Once the safety system is validated and the safety signature applied safety memory is protected the safety logic cannot be modified and all safety functions operate with SIL integrity If the safety partner is present the safety integrity will be SIL3 If no safety partner is present the safety integrity will be SIL2 On the standard side of the GuardLogix controller all functions operate like a regular Logix controller
With the introduction of the GuardLogix 5580 controller you can achieve up to SIL 2PLd (Category 3) with one controller and the use of the safety task and safety IO You must use a primary controller and a safety partner to achieve SIL 3PLe (Category 4)
Use Guard IOtrade modules for field device connectivity on Ethernet or DeviceNet networks and for safety interlocking between GuardLogix controllers use Ethernet or ControlNet networks Multiple GuardLogix controllers can share safety data for zone to zone interlocking or one GuardLogix controller can use distributed safety IO between different cellsareas
The GuardLogix controller has the standard features of a ControlLogix controller and these safety-related features
Application Description
Up to SIL 3 The GuardLogix controller system is type-approved and certified for use in safety applications up to and including SIL 3 according to IEC 61508 and applications up to and including PLeCat4 according to ISO 13849-1 For more information see the followingbull GuardLogix 5570 Controllers User Manual publication 1756-UM022 Provides information on how to install configure and operate

ControlLogix IO ModulesThe ControlLogix architecture provides a wide range of input and output modules to span many applications from high-speed digital to process control The ControlLogix architecture uses a ProducerConsumer model so that input information and output status can be shared among multiple controllers
Each ControlLogix IO module mounts in a ControlLogix chassis and requires a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all field-side wiring RTBs and IFMs are not included with the IO modules They must be ordered separately

AccessoriesmdashIO Modules
1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

Example ConfigurationmdashRedundant IO System
The 1715 redundant IO system lets a ControlLogix 5570 controller communicate to a remote redundant IO chassis over an EtherNetIP network The 1715 redundant IO system provides fault tolerance and redundancy for critical processes by using a redundant adapter pair and redundant IO module pairs
The redundant IO system must be connected to a ControlLogix 5570 system via an EtherNetIP network All connections are established via the Ethernet network by using the topologies that the 1756-EN2TR communication bridge supports
For detailed specifications see the 1715 Redundant IO System Specifications Technical Data publication 1715-TD001

ControlLogix IO ModulesThe ControlLogix architecture provides a wide range of input and output modules to span many applications from high-speed digital to process control The ControlLogix architecture uses a ProducerConsumer model so that input information and output status can be shared among multiple controllers
Each ControlLogix IO module mounts in a ControlLogix chassis and requires a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all field-side wiring RTBs and IFMs are not included with the IO modules They must be ordered separately

1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

ControlLogix IO ModulesThe ControlLogix architecture provides a wide range of input and output modules to span many applications from high-speed digital to process control The ControlLogix architecture uses a ProducerConsumer model so that input information and output status can be shared among multiple controllers
Each ControlLogix IO module mounts in a ControlLogix chassis and requires a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all field-side wiring RTBs and IFMs are not included with the IO modules They must be ordered separately

1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

GuardLogix Controllers
A GuardLogix controller is a ControlLogix controller that also provides safety control
During development safety and standard have the same rules multiple programmers online editing and forcing are all allowed Once the safety system is validated and the safety signature applied safety memory is protected the safety logic cannot be modified and all safety functions operate with SIL integrity If the safety partner is present the safety integrity will be SIL3 If no safety partner is present the safety integrity will be SIL2 On the standard side of the GuardLogix controller all functions operate like a regular Logix controller
With the introduction of the GuardLogix 5580 controller you can achieve up to SIL 2PLd (Category 3) with one controller and the use of the safety task and safety IO You must use a primary controller and a safety partner to achieve SIL 3PLe (Category 4)
Use Guard IOtrade modules for field device connectivity on Ethernet or DeviceNet networks and for safety interlocking between GuardLogix controllers use Ethernet or ControlNet networks Multiple GuardLogix controllers can share safety data for zone to zone interlocking or one GuardLogix controller can use distributed safety IO between different cellsareas
The GuardLogix controller has the standard features of a ControlLogix controller and these safety-related features
Application Description
Up to SIL 3 The GuardLogix controller system is type-approved and certified for use in safety applications up to and including SIL 3 according to IEC 61508 and applications up to and including PLeCat4 according to ISO 13849-1 For more information see the followingbull GuardLogix 5570 Controllers User Manual publication 1756-UM022 Provides information on how to install configure and operate

ControlLogix IO ModulesThe ControlLogix architecture provides a wide range of input and output modules to span many applications from high-speed digital to process control The ControlLogix architecture uses a ProducerConsumer model so that input information and output status can be shared among multiple controllers
Each ControlLogix IO module mounts in a ControlLogix chassis and requires a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all field-side wiring RTBs and IFMs are not included with the IO modules They must be ordered separately

1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

ControlLogix ControllersThe ControlLogix controller provides a scalable controller solution capable of addressing many IO points
The controller can be placed into any slot of a ControlLogix chassis and multiple controllers can be installed in the same chassis Multiple controllers in the same chassis communicate with each other over the backplane (just as controllers can communicate over networks) but operate independently
ControlLogix controllers can monitor and control IO across the ControlLogix backplane and over IO links ControlLogix controllers can communicate over EtherNetIP ControlNet DeviceNet DH+ Remote IO and RS-232-C (DF1DH-485 protocol) networks and many third-party process and device networks To provide communication for a ControlLogix controller install the appropriate communication interface module into the chassis

GuardLogix Controllers
A GuardLogix controller is a ControlLogix controller that also provides safety control
During development safety and standard have the same rules multiple programmers online editing and forcing are all allowed Once the safety system is validated and the safety signature applied safety memory is protected the safety logic cannot be modified and all safety functions operate with SIL integrity If the safety partner is present the safety integrity will be SIL3 If no safety partner is present the safety integrity will be SIL2 On the standard side of the GuardLogix controller all functions operate like a regular Logix controller
With the introduction of the GuardLogix 5580 controller you can achieve up to SIL 2PLd (Category 3) with one controller and the use of the safety task and safety IO You must use a primary controller and a safety partner to achieve SIL 3PLe (Category 4)
Use Guard IOtrade modules for field device connectivity on Ethernet or DeviceNet networks and for safety interlocking between GuardLogix controllers use Ethernet or ControlNet networks Multiple GuardLogix controllers can share safety data for zone to zone interlocking or one GuardLogix controller can use distributed safety IO between different cellsareas
The GuardLogix controller has the standard features of a ControlLogix controller and these safety-related features

ControlLogix IO ModulesThe ControlLogix architecture provides a wide range of input and output modules to span many applications from high-speed digital to process control The ControlLogix architecture uses a ProducerConsumer model so that input information and output status can be shared among multiple controllers
Each ControlLogix IO module mounts in a ControlLogix chassis and requires a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all field-side wiring RTBs and IFMs are not included with the IO modules They must be ordered separately

1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

GuardLogix Controllers
A GuardLogix controller is a ControlLogix controller that also provides safety control
During development safety and standard have the same rules multiple programmers online editing and forcing are all allowed Once the safety system is validated and the safety signature applied safety memory is protected the safety logic cannot be modified and all safety functions operate with SIL integrity If the safety partner is present the safety integrity will be SIL3 If no safety partner is present the safety integrity will be SIL2 On the standard side of the GuardLogix controller all functions operate like a regular Logix controller
With the introduction of the GuardLogix 5580 controller you can achieve up to SIL 2PLd (Category 3) with one controller and the use of the safety task and safety IO You must use a primary controller and a safety partner to achieve SIL 3PLe (Category 4)
Use Guard IOtrade modules for field device connectivity on Ethernet or DeviceNet networks and for safety interlocking between GuardLogix controllers use Ethernet or ControlNet networks Multiple GuardLogix controllers can share safety data for zone to zone interlocking or one GuardLogix controller can use distributed safety IO between different cellsareas
The GuardLogix controller has the standard features of a ControlLogix controller and these safety-related features

1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

GuardLogix Controllers
A GuardLogix controller is a ControlLogix controller that also provides safety control
During development safety and standard have the same rules multiple programmers online editing and forcing are all allowed Once the safety system is validated and the safety signature applied safety memory is protected the safety logic cannot be modified and all safety functions operate with SIL integrity If the safety partner is present the safety integrity will be SIL3 If no safety partner is present the safety integrity will be SIL2 On the standard side of the GuardLogix controller all functions operate like a regular Logix controller
With the introduction of the GuardLogix 5580 controller you can achieve up to SIL 2PLd (Category 3) with one controller and the use of the safety task and safety IO You must use a primary controller and a safety partner to achieve SIL 3PLe (Category 4)
Use Guard IOtrade modules for field device connectivity on Ethernet or DeviceNet networks and for safety interlocking between GuardLogix controllers use Ethernet or ControlNet networks Multiple GuardLogix controllers can share safety data for zone to zone interlocking or one GuardLogix controller can use distributed safety IO between different cellsareas
The GuardLogix controller has the standard features of a ControlLogix controller and these safety-related features

1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

ControlLogix ControllersThe ControlLogix controller provides a scalable controller solution capable of addressing many IO points
The controller can be placed into any slot of a ControlLogix chassis and multiple controllers can be installed in the same chassis Multiple controllers in the same chassis communicate with each other over the backplane (just as controllers can communicate over networks) but operate independently
ControlLogix controllers can monitor and control IO across the ControlLogix backplane and over IO links ControlLogix controllers can communicate over EtherNetIP ControlNet DeviceNet DH+ Remote IO and RS-232-C (DF1DH-485 protocol) networks and many third-party process and device networks To provide communication for a ControlLogix controller install the appropriate communication interface module into the chassis

GuardLogix Controllers
A GuardLogix controller is a ControlLogix controller that also provides safety control
During development safety and standard have the same rules multiple programmers online editing and forcing are all allowed Once the safety system is validated and the safety signature applied safety memory is protected the safety logic cannot be modified and all safety functions operate with SIL integrity If the safety partner is present the safety integrity will be SIL3 If no safety partner is present the safety integrity will be SIL2 On the standard side of the GuardLogix controller all functions operate like a regular Logix controller
With the introduction of the GuardLogix 5580 controller you can achieve up to SIL 2PLd (Category 3) with one controller and the use of the safety task and safety IO You must use a primary controller and a safety partner to achieve SIL 3PLe (Category 4)
Use Guard IOtrade modules for field device connectivity on Ethernet or DeviceNet networks and for safety interlocking between GuardLogix controllers use Ethernet or ControlNet networks Multiple GuardLogix controllers can share safety data for zone to zone interlocking or one GuardLogix controller can use distributed safety IO between different cellsareas
The GuardLogix controller has the standard features of a ControlLogix controller and these safety-related features

1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

GuardLogix Controllers
A GuardLogix controller is a ControlLogix controller that also provides safety control
During development safety and standard have the same rules multiple programmers online editing and forcing are all allowed Once the safety system is validated and the safety signature applied safety memory is protected the safety logic cannot be modified and all safety functions operate with SIL integrity If the safety partner is present the safety integrity will be SIL3 If no safety partner is present the safety integrity will be SIL2 On the standard side of the GuardLogix controller all functions operate like a regular Logix controller
With the introduction of the GuardLogix 5580 controller you can achieve up to SIL 2PLd (Category 3) with one controller and the use of the safety task and safety IO You must use a primary controller and a safety partner to achieve SIL 3PLe (Category 4)
Use Guard IOtrade modules for field device connectivity on Ethernet or DeviceNet networks and for safety interlocking between GuardLogix controllers use Ethernet or ControlNet networks Multiple GuardLogix controllers can share safety data for zone to zone interlocking or one GuardLogix controller can use distributed safety IO between different cellsareas
The GuardLogix controller has the standard features of a ControlLogix controller and these safety-related features
Application Description
Up to SIL 3 The GuardLogix controller system is type-approved and certified for use in safety applications up to and including SIL 3 according to IEC 61508 and applications up to and including PLeCat4 according to ISO 13849-1 For more information see the followingbull GuardLogix 5570 Controllers User Manual publication 1756-UM022 Provides information on how to install configure and operate

1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

GuardLogix Controllers
A GuardLogix controller is a ControlLogix controller that also provides safety control
During development safety and standard have the same rules multiple programmers online editing and forcing are all allowed Once the safety system is validated and the safety signature applied safety memory is protected the safety logic cannot be modified and all safety functions operate with SIL integrity If the safety partner is present the safety integrity will be SIL3 If no safety partner is present the safety integrity will be SIL2 On the standard side of the GuardLogix controller all functions operate like a regular Logix controller
With the introduction of the GuardLogix 5580 controller you can achieve up to SIL 2PLd (Category 3) with one controller and the use of the safety task and safety IO You must use a primary controller and a safety partner to achieve SIL 3PLe (Category 4)
Use Guard IOtrade modules for field device connectivity on Ethernet or DeviceNet networks and for safety interlocking between GuardLogix controllers use Ethernet or ControlNet networks Multiple GuardLogix controllers can share safety data for zone to zone interlocking or one GuardLogix controller can use distributed safety IO between different cellsareas
The GuardLogix controller has the standard features of a ControlLogix controller and these safety-related features
Application Description

1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

GuardLogix Controllers
A GuardLogix controller is a ControlLogix controller that also provides safety control
During development safety and standard have the same rules multiple programmers online editing and forcing are all allowed Once the safety system is validated and the safety signature applied safety memory is protected the safety logic cannot be modified and all safety functions operate with SIL integrity If the safety partner is present the safety integrity will be SIL3 If no safety partner is present the safety integrity will be SIL2 On the standard side of the GuardLogix controller all functions operate like a regular Logix controller
With the introduction of the GuardLogix 5580 controller you can achieve up to SIL 2PLd (Category 3) with one controller and the use of the safety task and safety IO You must use a primary controller and a safety partner to achieve SIL 3PLe (Category 4)
Use Guard IOtrade modules for field device connectivity on Ethernet or DeviceNet networks and for safety interlocking between GuardLogix controllers use Ethernet or ControlNet networks Multiple GuardLogix controllers can share safety data for zone to zone interlocking or one GuardLogix controller can use distributed safety IO between different cellsareas
The GuardLogix controller has the standard features of a ControlLogix controller and these safety-related features
Application Description

AccessoriesmdashIO Modules
1756 Removable Terminal Blocks
Removable terminal blocks (RTBs) provide a flexible interconnection between your plant wiring and 1756 IO modules The RTB plugs into the front of the IO module The type of module determines the RTB you need You can choose screw-clamp or spring-clamp RTBs
RTBs are not shipped with IO modules You must order them separately The standard housing on the front of the wiring arm is not necessarily deep enough for 25 mm2 (14 AWG) wiring If you plan to use 25 mm2 (14 AWG) wiring also order the extended housing For more information on Extended-Depth Housing see Rockwell Automationreg Knowledgebase article 41488 Use of the 1756-TBE Extended Terminal Housing You can access the article at httpsrockwellautomationcusthelpcom (login is required)
Wiring Systems
As an alternative to buying RTBs and connecting the wires yourself you can buy a wiring system of the following
bull Interface modules (IFMs) that provide the IO terminal blocks for Digital IO modules Use the prewired cables that match the IO module to the IFM
bull Analog interface modules (AIFMs) that provide the IO terminal blocks for analog IO modules Use the prewired cables that match the IO module to the AIFM
bull IO module-ready cables One end of the cable assembly is an RTB that plugs into the front of the IO module The other end has individually color-coded conductors that connect to a standard terminal block

GuardLogix Controllers
A GuardLogix controller is a ControlLogix controller that also provides safety control
During development safety and standard have the same rules multiple programmers online editing and forcing are all allowed Once the safety system is validated and the safety signature applied safety memory is protected the safety logic cannot be modified and all safety functions operate with SIL integrity If the safety partner is present the safety integrity will be SIL3 If no safety partner is present the safety integrity will be SIL2 On the standard side of the GuardLogix controller all functions operate like a regular Logix controller
With the introduction of the GuardLogix 5580 controller you can achieve up to SIL 2PLd (Category 3) with one controller and the use of the safety task and safety IO You must use a primary controller and a safety partner to achieve SIL 3PLe (Category 4)
Use Guard IOtrade modules for field device connectivity on Ethernet or DeviceNet networks and for safety interlocking between GuardLogix controllers use Ethernet or ControlNet networks Multiple GuardLogix controllers can share safety data for zone to zone interlocking or one GuardLogix controller can use distributed safety IO between different cellsareas
The GuardLogix controller has the standard features of a ControlLogix controller and these safety-related features
Application Description

GuardLogix Controllers
A GuardLogix controller is a ControlLogix controller that also provides safety control
During development safety and standard have the same rules multiple programmers online editing and forcing are all allowed Once the safety system is validated and the safety signature applied safety memory is protected the safety logic cannot be modified and all safety functions operate with SIL integrity If the safety partner is present the safety integrity will be SIL3 If no safety partner is present the safety integrity will be SIL2 On the standard side of the GuardLogix controller all functions operate like a regular Logix controller
With the introduction of the GuardLogix 5580 controller you can achieve up to SIL 2PLd (Category 3) with one controller and the use of the safety task and safety IO You must use a primary controller and a safety partner to achieve SIL 3PLe (Category 4)
Use Guard IOtrade modules for field device connectivity on Ethernet or DeviceNet networks and for safety interlocking between GuardLogix controllers use Ethernet or ControlNet networks Multiple GuardLogix controllers can share safety data for zone to zone interlocking or one GuardLogix controller can use distributed safety IO between different cellsareas
The GuardLogix controller has the standard features of a ControlLogix controller and these safety-related features
Application Description
