Posted 26 Apr 2018 Old obsolete platform phased out decades ago... There is no other controller you can use that I/O with. Need to start over with a new controller. Software was called SyMate and was DOS based. Needed a special programming cable if I remember right. I last touched one in 2002, replacing it with a newer PLC.
