This is all very new to me.i need help as i am trying to communicate 2 omron CJ1M PLC's on an ethernet using cx-programmer. Basically, i just want to run a simple ladder logic on one PLC which then communicates to the next PLC to excute its ladder logic. I dont know how to call the other PLC when i am doing the ladder logic in cx-programmer. Do I need to set up a network in cx-programmer? If so, how do i do that. All help is appreciated very much....
