I'm an electrician in an industrial plant and have always had a laptop available to hook up to plc's. Recently I Ebay'd a SLC 5/03, 1747-PIC & used desktop(stand-alone, no network) for a home project. I installed the old RSLogix/RSLinx (ver2.0)I had and can't establish a link on ethernet or serial (com1). There are several things on the web about RSLinx compatibility with Windows XP SP3. The ver2.53 web release from Rockwell won't install on XP. Can someone tell how to make the old work or point me somewhere to get something that will?
