This protocol is used between a master unit and several slaveunits. The master and slaves communicate using RS232 or RS485.1.1.1 - Communication over RS232 networksThis type of communication is used in short-distance field bus networks only. Communications can be made atbaud rates of 300 to 115,200 bauds. RS232 links can only be established between one master and one slave.1.1.2 - Communication over RS485 networksThis type of communication is used in medium-distance field bus networks only. Communications can be madeat baud rates of 300 to 115,200 bauds. RS232 links can be established between one master and up to 31 slaves.Caution: the network must be considered as a chain made up of links:- the master is at the start of the chain,- the slaves represent the intermediate links (RS485i),- the last slave (RS485f) forms the end of the chain.

Therefore,the seven main information categories above are available for both machines.Reminder: a multi-spindle station can include no more than 32 spindles (MULTICVI).4.1 - Date programming zoneThis zone is used to program the data and time across a network so that the time in the PLCs is coherent.When the PLC accesses the date, it must reset the acknowledge flag (least significant byte) and set the most significantbyte.Example:Control word for access to the dateWhen the CVI has finished programming or reading the date, it resets the most significant byte and provides a report inthe least significant byte:4.2 - Input / output zoneA machine has 14 inputs and 16 x 24 Volt outputs which are in read only mode.Description Access Size TypeYear (0 to 59 for 2000 to 2059) R/W 1 IntegerMonth (1 to 12) R/W 1 IntegerDay (1 to 31) R/W 1 IntegerHours (0 to 23) R/W 1 IntegerMinutes (0 to 59) R/W 1 IntegerSeconds (0 to 59) R/W 1 IntegerControl word for access to the dateR/W 2 IntegerAction (PLC)Most significant byte(first byte - Hexa.)Least significant byte(second byte - Hexa.)Description of the actionWrite 40 00 Request to read the dateRead 00 80 Date information availableData processing timeWrite 80 00 Request to write the date and timeRead 00 80 Date and time successfully loadedBit7 Bit6 Bit6 Bit4 Bit3 Bit2 Bit1 Bit0Completed NOK Year errorMonth errorDay error Hours errorMinutes errorSeconds error1 Yes 1 NOK 1 Error 1 Error 1 Error 1 Error 1 Error 1 Error0 No 0 OK 0 OK 0 OK 0 OK 0 OK 0 OK 0 OKMODBUS / MODBUS TCPPart no 6159935751Issue no 01Language EnglishDate 04/2008Page 18 / 224.2.1 - 24 V Inputs/OutputsThis zone represents the 24 Volt inputs/outputs of the tightening controller. They can be accessed in read-onlymode.4.2.2 - Network inputs/outputsThesamefunctionsexecutedbythe24VinputscanbeusedwithMODBUS.However,notalloftheinputfunctions are available over MODBUS type field bus networks. Only the "Cycle start", "Direction", "Report request", "Emergency stop", "Reset", and "Clear fault" functionsare available across field networks.4.2.3 - Input maskMasks are used to enable or disable the functions of maskable inputs.Masks are only of any use with tightening controllers without an IsaGRAF application.Tightening controllers with an IsaGRAF application can redefine their network inputs/outputs.Example:To enable the "Cycle start" over the field bus network and disable this function by the 24V input, theinput mask must be set to 0x0020 (bit n 5 is set).When an input can be accessed by the network and a 24 V input, an "OR" function is executed between thenetwork input and the 24 V input.4.3 - Machine 1 and 2 write zone4.3.1 - Cycle number selectionThis data is only taken into consideration if "Source of cycle number" is set to "PLC" in the tightening controller.4.3.2 - Spindle validationThis data is only taken into consideration when "Spindle validation" is set to "PLC" in the tightening controller.This list is a 32-bit long word. Each bit corresponds to one spindle.A list of spindles is encoded as follows.BitInput Description(See Input mask)Maskable Output Description0 Cycle 1 Cycle 1 acknowledge1 Cycle 2 Cycle 2 acknowledge2 Cycle 4 Cycle 4 acknowledge3 Cycle 8 Cycle 8 acknowledge4 Cycle 16 Cycle 16 acknowledge5 Cycle startReport OK6 DirectionReport NOK7 Report requestN of cycles OK8 Emergency stop (ES)Running9 ResetReady10 Clear fault-11 Spindle validation -12 Synchro In Reverse run detected 13 External stop Reverse run detected 14 Synchro out15 -Byte N Spindles1st byte Spindles 25 to 322nd byte Spindles 17 to 243rd byte Spindles 9 to 164th byte Spindles 1 to 8MODBUS / MODBUS TCPPart no 6159935751Issue no 01Language EnglishDate 04/2008Page 19 / 224.3.3 - Specific codeWriting the specific code in the memory serves two purposes:- to memorise a code in the tightening results of the tightening controller,- to select a cycle using a code. In order to use the code as the source of the cycle number, the followingoptions must be selected:Note: the PLC must program the specific code and its length in a single record. When the controller takes thespecific code into account, it resets the length.4.4 - Machine 1 and 2 read zoneNote: the size of the machine read zone depends on the number of spindles in the machine. 4.4.1 - Bar codeThis code is the result of reading a standard bar code connected to the station, or copying of the specific code inthe write zone.If the code is less than 30 characters in length, the unused memory is filled with zeros (0x00).4.4.2 - Spindle listThis list is a 32-bit long word. Each bit corresponds to one spindle. A list of spindles is encoded as follows.4.4.3 - Number of spindlesFor a TWINCVI or a MODCVI, the maximum number of spindles per machine is 2.For a MULTICVI, the maximum number of spindles per machine is 32.4.4.4 - Selected cycleThis zone is the equivalent to the cycle acknowledge. 4.4.5 - Number of programmed OK cyclesThis zone contains the number of OK cycles programmed in the selected cycle.4.4.6 - Number of executed OK cyclesThis zone contains the number of executed OK cycles in the selected cycle since the last reset.4.4.7 - General reportThis zone contains the general report of the last executed cycle.4.4.8 - Result numberThis value indicates the number of the result (0 to 65535). This value is reset when it reaches the maximum.4.4.9 - ReportThe reports per spindle are encoded as follows:Byte n Spindles1st byte Spindles 25 to 322nd byte Spindles 17 to 243rd byte Spindles 9 to 164th byte Spindles 1 to 80No general report1General report OK2General report NOKTension Torque rate Torque AngleX X x X X X x x"cycle source n" to "bar code","read by PLC" in the bar code settings.MODBUS / MODBUS TCPPart no 6159935751Issue no 01Language EnglishDate 04/2008Page 20 / 22Each setting may take the following values:4.5 - Machine 1 and 2 results zoneThe size used for this zone depends on the number of spindles and format.4.5.1 - Result format optionsThe results zone is made up of the following:- a general report,- a results zone, the size of which is the size of a spindle result multiplied by the number of spindles in themachine.The description of a result per spindle depends on three options programmed in the tightening controller:- The type of data saved is used to select whether the following data are saved: torque, angle, torque rateand tension.The type of data is programmed in word N 10 as follows:Example:word no. 10 = 0x0007Torque + Angle + Torque rate- The data format is used to select the type of data encoding: ASCII or floating IEEE 754.The data format is programmed in word N 11 as follows:- The type of saved values is used to select the following data for each type of data saved: tolerance, finalvalue and report. The type of values is programmed in word N 12 as follows:These three options are used to adapt the size and presentation of a result per spindle to the user's requirements.Remark: these options can be accessed through an option configuration utility.01 (binary) : Min.11 (binary) : OK10 (binary) : Max.00 (binary) : The spindle did not rotate or was stopped during the cycle.Bit 0 : TorqueBit 1 : AngleBit 2 : Torque rate0 : ASCII1 : floating MOTOROLA2 : floating INTEL0 : Tolerance + Final value + Report1 : Final Value + Report2 : ReportMODBUS / MODBUS TCPPart no 6159935751Issue no 01Language EnglishDate 04/2008Page 21 / 224.5.2 - Result per spindle read zoneThesizeofthiszonedependsonthenumberofspindlesandthesizeofeachresultdependsonthetyperequested.4.5.3 - Size of result per spindleDepending on the three options programmed in the tightening controller, the size of a spindle result takes thefollowing values:4.6 - Specific data zoneThis zone is used for specific applications. It can only be used with IsaGRAF applications. This memory zone can beaccessed by both the PLC and the IsaGRAF application of the tightening controller.The data stored in this memory zone is saved even when the controller power supply is cut.4.7 - Option zoneThis memory zone is read-only.
