Is it possible to put the serial port into an "Off" state in a Contrologix PLC? I have a high-faluting "Y" cable so that I can run 2 plcs out the same serial port. It works but has the expected problems.
So it would be great if I could place one of the ports at a time into a high impedance state so that I could use the other one.
Even when the PLC is not using the port for anything, its alive and watching the pins. And its impact is obvious.
