Hello DPC, [snip] ...
If it's Modbus RTU then you will have to get a CP341 with Modbus RTU driver (Master or Slave). This CPU will have a position in one of your ET200M racks. You can find more info in the links that can be found in the following FAQ. How do you download a loadable driver such as "Modbus Master (RTU)" into a CP341 that is connected to an S7-400 H system by means of an ET 200M? If it's Modbus TCP/IP then you will need S7 OpenMODBUS/TCP RED V2 . Best regards. H-H |

Hello DPC,
I'm not a communication expert but I think you can create your own driver and your own blocks for redundant communication. This package will save you lot of effort and it's trusted and supported. If I were you I would have boughtthis package. Best regards. H-H |
