I have a machine running with a Siemens 627b box pc connected to IO modules via ET200M interfaces and running a WinCC application. There is also a SIMATIC Flat Panel connected via DPI and USB via a Remote Panel Kit which basically converts the USB to a cat5 cable between the flat touch panel and the PC. My issue is that sporadically the screen variables lock up and the touch screen becomes inactive. The USB keyboard and mouse connected to the Flat Panel also stop working. If I move the keyboard and mouse to the local USB ports on the box PC they still do not work. At first I was thinking the OPC server was locking up and that is why the data on the screen was freezing up, however the loss of the USB functionality has got me thinking otherwise. Any ideas? Any other info that would help troubleshoot? Thanks!
