I would like to be able to connect my PLC's underground together. I would like to use a 1 or 2 pair wire.
My PLC's are about 2000' apart with the farthest one being about 4 miles from my computer outside. We currently have CO monitoring systems that can transmit these distances with 2 wires at about 36K. All of the manufacturers of the CO systems have developed their own communication based on RS422 or RS485 or something similar. Does anyone make a "box" that can allow AB's Micrologix to do this?
Thanks for your help,
Heath
