All control functions required for the faultlessoperation of the I/O functions are carried out by the Coupler/Controller. Theconnection to different fieldbus systems is established by each of the corre-sponding Coupler/Controller, e.g. for PROFIBUS, INTERBUS, CAN,MODBUS etc. In this way a change of the fieldbus system is possible.The programmable fieldbus controller 750-842 combines the ETHERNETTCP/IP functionality of the fieldbus coupler 750-342 with the functionality ofa Programmable Logic Control (PLC). Programming of the application is donewith WAGO-I/O-PRO in accordance with IEC 61131-3, covering all 5 pro-gramming languages. The programmer can access all fieldbus and I/O data.
