Haris Posted August 15, 2019 Report Share Posted August 15, 2019 Hi everyone, I am trying to download my project to my Jazz JZ20-R31 PLC from U90Ladder. When I go to Controller -> M90 OPLC Settings, I click "Get Version" and I do get the correct data. "Get Time & Date" works as well, and so do the other PLC -> PC functions it seems. But when I click "Set Time & Date" or "Reset" or other PC -> PLC functions including "Download", I get an error message saying: Quote Run-time error '5': Invalid procedure call or argument When I click "OK" the program closes. A colleague of mine has also installed U90Ladder following the same procedure I have, and everything went smoothly for him (we used the same PLC). This leads me to think that the problem is system-wide for me. I am using Windows 10. Thank you. Haris Quote Link to comment Share on other sites More sharing options...
