I plan on replacing a network of three old modicon quantum PLCs with SNAP-PAC-EB1 and Opto IO units. The existing data communications between the old modicon units use RG-11 coax. When I replace the modicon PLCs with the SNAP-PAC-EB1s, I will need to communicate with them via ethernet but the third modicon unit is quite a distance away - close to a mile. I am considering different options to communicate with the EB-1 that will replace the third modicon quantum unit. One option is to utilize the existing RG-11 coax and a converter. Which brings up my first question: Are there any recommended RG-11 to ethernet converters that would work for this situation? Or does anyone have any other ideas that I can use to establish data communications at such a distance?
Otherwise, my other thought is just replace the RG-11 with a Cat 7 cable.
