All about IO-Link

IO-Link Brings Intelligence to Simple Devices IO-Link is not an industrial network, but rather a

simple protocol that adds communication capabilities to devices connected to existing industrial networks. A point-to-point connection

Former named by Siemens: IQ sense IO-Link uses the existing 24 VDC point-to-point

wiring between field devices and I/O channels to transmit additional data via a UART-based pulse modulation over distances of up to 15 meters.

Driven mainly by sensor companies. Own field bus organisation:

Customer benefitsCustomer benefits Reducing the projection and installation costs by

means of a standardised interface Reducing the commissioning and set-up times by

means of transparent parameter storage Reducing machine downtimes by means of

differentiated diagnosis Sound investment due to the compatibility with the

installed base and field bus neutrality

Introduction to Ethernet and Industrial Ethernet

TV-NP/VUK

What is Ethernet?

With the term Ethernet many elements of a typical office network structure are referenced

The official standard of ethernet defined by the IEEE (Institute of Electrical and Electronics Engineers) is IEEE 802.3 CSMA/CD (Carrier Sense Multiple Access with Collision Detection)

Ethernet is a definition of the group physical LAN (Local Area Network) IEEE 802

Ethernet is a group of defined protocols on defined hardware interfaces

Ethernet is an electronic medium for software based transportation, communication and application protocols

Ethernet in the ISO/OSI network model

Ethernet is defined in the levels 1 and 2 of the ISO/OSI network model

The upper level of the OSI model can also work with other network access definitions then ethernet

Ethernet describes cables, communication media and hardware interfaces in level 1. Data access via CSMA/CD and the Ethernet Frame are described in level 2

Ethernet is common in office and home networks. PCs, printers and servers use typically ethernet

Ethernet address

Every ethernet device has a worldwideunique ethernet address (also called MAC address or MAC-ID)

In the levels of the network access of ethernet, devices just communicate with each other via the MAC-IDs

Via ethernet the devices of a network can communicate with each other.To communicate with other networks one device (e.g. network router) has to use other network access medias (Telephone network) and protocols of the upper level

TCP/IP stack

The TCP/IP stack is the core of IT technology The logical communication, between devices in

one or more networks, is handled at level 3 and 4 of the network model witch is referencedby the term TCP/IP

Level 5 and 6 (Session management) are not used in the ethernet environment

Level 7 describes the application protocols, which are used between programs(e.g. Web browser and web server)

The set of protocols of level 3 to 7 is often described as TCP/IP stack or TCP/IP suite

Up to 4.3 million address are so available Various address ranges are defined for

TCP and UDP The transportation protocols

TCP Transfer Control Protocol TCP creates a virtual connection. The data is

divided into packets. This packets are sent to the receiver. If packets get lost the addressor sends them again.Typically used for file transfer.

UDP User Datagram Protocol UDP sends packets without acknowledgments to

the receiver. It is used for fast applications.

TV-NP/VUK

Application protocols

Application protocols are used to transfer data between programs

Examples of application protocols are HTTP (Hyper Text Transfer Protocol)

used for the transfer of web-pages or web-files (PDF) between a web-server and a we-browser

FTP (File Transfer Protocol)used to transfer files between a local and a server-based file system

SMTP (Simple Mail Transfer Protocol)used to send emails between local email-programs and email-server

What is Industrial Ethernet?

Industrial Ethernet describes:

The adaptation of ethernet components into the rough industrial environment

Fieldbus based communication protocols for use with or inside the TCP/IP stack

The possibility of information access and engineering advantages through the local network and IT-technology

TV-NP/VUK

Industrial Ethernet hardware components

Typical components in ethernet networks are hubs and switches with RJ45 connectors

The industrial environment defines higher conditions in the field:- High protection rates, e.g. IP65/67- Temperature- Vibration- Reliability,

Typical office components cannot fulfill such conditions

New definitions for special business orientations define special components

The prices of industrial ethernet components are much more expensive

Example of standard office components

What is new with advanced fieldbus systems

Modular hardware configurationOptimal and easy hardware configurations of complex and modular products may help to map I/O data to the plc projects and to locate easily parameters and diagnostic data

Device and module parameterizationNeed of setting up diagnostics and configuration of decentral field devices

Integrated diagnosticsHelps to identify failures very fast and to visualize them transparently. Reduction of down-time

Bandwidth for process data and devicesControl of mixed signals like analogue and digital signals

Acyclic data accessChange of parameters and validation of advanced diagnostics during the run-time of the PLC program

TV-NP/VUK

What is new with industrial ethernet fieldbus system

Higher bandwidthEnables communication between controllers.Integration of more complex products with large I/O size

Expansion of network technology More devices may be integrated into the fieldbus networks due to IP addressing technology with sub-networks.Network peripheries like WLAN routers, switches, proxy and gateway servers may be included.

Integration of IT-TechnologyMore diagnostic tools which are able to communicate to the field devices via ethernet from any point inside the control architecture.

TV-NP/VUK

Industrial Ethernet vs. fieldbus competition or co-existence?Target situation Current situation

One industrial Ethernet protocol > 5 relevant industrial Ethernet protocols

Use of hardware from PCs and consumer products results in uniform,

standardised products.

Didnt happen: necessity for individualised hardware and designs for

each system, few usable electronic components from PC technology

Reduced hook-up costs per device thanks to large quantities and

inexpensive hardware. Vision: industrial Ethernet in the individual

sensor/actuator

Mission botched: price increase for hook-up costs per node due to

quantity splitting, high performance electronics and individual design

Utilisation of IT functions in the front-end automation device provides a

transparent link to master systems, as well as increased data

communication.

Not previously utilised: IT functions are usually only used as of the

control level; few projects with IT at the field level.

High performance communication with regard to data width, speed and

synchronisation allows for the integration of motion control applications

into an network with other field devices.

Mission accomplished: variants with fast, synchronous data

communication in co-existence with standard communications on a single

bus.
