Hi everyone I am trying to communicate two Premium PLCs by using messaging function. I have two premium PLCs ( ETY port built in) with IP address : PLC1: 135.124.15.1 (Server) PLC2: 135.124.15.2 (client) I want to exchange data between two PLCs by using modbus TCP protocol ( client/Server), But I don't know how to configure which is client and which is server. I configured and programed for PLC2: in IP configuration : IP address : 135.124.15.2 I ran two PLCs but I have not had result. please give me suggestion thank a lot Edited 20 Oct 2009 by ballvietnam

Much better, You could configure I/O Scanning service only in one PLC. You don't need to program any read_var or whatever. See the H elp

I agree I\O scanning is the best way of doing this, once setup it just looks after itself, no READ_VAR's to initiate or status words to check, its almost too simple
