Hi all, calling on the help of all the Moeller wizards out there! I can't get my laptop to communicate properly with a PS306 using a UM1.5-1 cable, and S30 software. It will compare and start/stop the plc but not transfer any source code (fault given: "the connection between PRG and PS is interrupted"). I've repeated the excercise using my desktop and it all works fine, so i've ruled out the cable and Plc and software as the problem, so that leaves just the laptop. Using the same laptop, communication with a PS4 range is fine. Any ideas of what could be done to resolve my problem?????
