I’m trying to use an Anybus X-gateway to connect a Rockwell PLC with a JUMO HMI, the PLC is Ethernet/IP while the HMI is Modbus. The PLC only needs to read from the HMI so all transactions are set up to read HMI registers.
In Rockwell Studio 5000 the Anybus is set up as a generic module. The transaction registers show up when the PLC is in program mode but as soon as the PLC is set to “RUN” mode the Anybus goes idle and all the registers are set to 0. Everything tests fine until I need to actually run it.
Any ideas on why this happens would be welcome.
