6.5. PLC Communication Environment SettingThe PLC communication environmental settings must be made to perform PLCcommunication. The system data settings are made by the loader communication.1. Turn on the power of the Z-TIO-C or Z-TIO-D module.(PLC power is off.)2. On the personal computer, set the communication data of the PLC communicationenvironment indicated below.3. When the settings for the communication data of the PLC communication environmentare completed, turn the power of the Z-TIO-C/D module off, and then turn it on again.When the power is turned ON, the changed system data values are enabled.Set the communication data for each module. After completing the communicationsettings of the first module, connect the loader communication cable to the nextmodule and set the PLC communication environment.Connect to loader communicationcable of next module.Loader communication cable(W-BV-01) [Option]Z-TIO-C orZ-TIO-D module• Communication data list (PLC communication environment)RO: Read only data R/W: Read and Write dataNameRKC ModbusAttri-FactoryIden- register address DigitsData rangebuteset valuetifier HEX DECStation number QV 0164 356 7 R/W 0 to 310Set the PLC station number.
