I want to communicate in the following manner PC ethernet port to ENIW ethernet port using ethernet cross over cable and RS 232 port to SLC channel0(configured as DH485) via a 1761-CBL-PM02 series C cable. But please tell me if there will b any issue with channel 0 of slc is configured as DH485 and ENIW has rs 232 port.

no....the slc 9-pin port is rs232 levels.....its not rs485....dh485 is a protocol not a hardware specification......so the Ethenet module uses dh485 through its rs232 port....same as the plc. bob

The 1761-NET-ENIW supports DF1 Full Duplex protocol not DH485. See pictures below, exerts from the manual. You may want to consider this product, see link. http://www.multi-gateways.com/ Edited 3 Sep 2013 by Mickey
