I went to a site that has 2 micrologics 1100 on a network. ip addresses ending 100 and 101. RS links detects both nodes. I was able to go online with 101 through ethernet IP. i had no sucess with 100. i could get acess with serial port. all com settings for ch1 are identical for both plc,s except ip address of course. The plc,s are communicating to each other using the msg instruction and this is working properply. I was able to do all required tasks over the serial port was wondering if the msg instruction takes over the port, but i could get coms to plc2 any ideas.
