I have a comm problem that I thought I would shoot over here before I start reinstalling stuff. I administer a SCADA system using AB PLC5s, CompactLogix, AB vfds, and AB power monitors. All AB stuff. SCADA is Proficy iFix. Here is the issue - I have one PLC 5/80E that has stopped responding to the RSLINX OEM app on my development computer. It will talk to other SCADA boxes on the network and is servicing the iFix HMIs just fine. All other devices are responding. I can ping it from my development box. I can bring up the web page for it with my development box. It just stopped talking to RSLinx. This has been communication for years. I am thinking i need to re-install RSLinx on my development box. I have not done any updates at all. Anyone have this happen to them?
