Hello,
We had CPU ET200s (6Es7 151-8AB01-0AB0) and ET200S 1SI Modbus CP MLFB No. 6ES7-138-4DF11-0AB0.
We were modbus master and all worked fine.
Now we have to change PLC, instead of Et200s we gonna put CPU315-2 PN/DP.
Since we have to change PLC, if we add also distributed module for ET200s ->
6Es7 151-3AA23 - 0AB0 and put
ET200S 1SI Modbus CP MLFB No. 6ES7-138-4DF11-0AB0 on it will MODBUS RTU - will it work on this way with the same code that was running on previous configurationWe had CPU ET200s (6Es7 151-8AB01-0AB0) and ET200S 1SI Modbus CP MLFB No. 6ES7-138-4DF11-0AB0.) with FB2 and FB3 functions.
