My customer has redundant GE CPE330s connected to redundant Prosoft modules via connection to the ETM001 cards. They were successful in setting up the COMM REQ function blocks to communicate with the Prosoft Modbus modules.They wish to make another connection to a DeltaV EIOC (Modbus TCP) module, and they are wondering if there is anything else they need to consider in their programming/config of the COMM REQ function blocks. Other than MB addressing and IP address, is there potentially anything in the DCS programming or config they should be aware of, or will their programming essentially follow the same process as for connection to the Prosoft modules?
