A few weeks ago while walking through the back part of our plant an coworker and I found an old GE Versamax Micro PLC (IC200UDR005-BB) on the bottom of an old fixture that was thrown into a scrap. We decided to pick it up and plug it in. the power, run, and ok LEDs all turn on when you plug the controller in. when you energize all of the inputs they all come on like they're supposed to. Our guess is that this was tossed because this is an antiquated fixture that has been obsolete for quite some time. All of our PLCs now are Allen Bradley. I already have Proficy machine edition 9.7 on my home PC. I bought a PLCCables.com IC200CBL500A to communicate with this processor. The problem Im having is evertime i try to connect Proficy gives me an error and says unable to connect. The Error is 8502: proficy cannont connect because another application is using the Port that proficy needs. The target properties match the PC Port setting. The CPU settings are kind of a guess but im using the default 19200 baud, odd parity, 1 stop bit. Sometimes it will actually try to connect if you try it after a while but it just times out and gives Error 8503 time out. when i turn the run toggle switch off the run LED does turn off, but at this point it doesnt seem to matter if thats on or off.
