Question regarding 3150 MCM

1 post in this topic


Iam using an SLC 500 PLC with 1747 KE (DH485/RS232C interface module) for modbus communication. this module is now faulty and replacement required.

My question is 1747 KE (DH485/RS232C interface module) and the prosoft 3150-MCM are the same or not.

 The old module have two boards on it while the new one have only one board. this confuses me.
