I’m trying to connect to a S7-200 plc with a pc running STEP7-MICRO/WIN v4.0.0.81 and a PPI to USB cable. This connection worked fine before. But now after the last download (and a few days) the connection will not work. I tried connecting to different ports on either side (pc and PLC). I Even tried a different computer and fresh software. If anyone has any idea what could have change or if there is a way to reset the plc back to factory settings. It would be greatly appreciated
