Thanks a lot.

RCOM is basically Modbus RTU. But unfortunately it is not completely compatible.
If you're not able to upgrade the RCOM devices, then you can build a custom serial interface with standard functions in the AC800M SerialLib and connect to the RCOM slaves using a CI853. It's quite possible that someone has already done this.

You could use ABB AC500 as protocol converter. AC500 supports RCOM and you can convert from RCOM to MODBUS RTU or TCP with it.
