bjarni Posted August 19, 2022 Report Share Posted August 19, 2022 Hello, I was moving my Unlogic project to another computer (two other computers actually) and upgrading it to the newest version (1.32.98). Everything seems normal on one computer(A) , but when I move to the other one (B) I get the "THe project currently in the PLC does not match the current project" when trying to get Online albeit both computers are using the same project file. If I try to download from (B) I get a message "Unilog was unable to read Global Tags information from PLC..." and if I continue from there then it stops with a message about an unknown error - and nothing is downloaded. Anyone who has some input on this ? Thanks, Bjarni Quote Link to comment Share on other sites More sharing options...
Gabriel Franco Posted August 19, 2022 Report Share Posted August 19, 2022 I noticed that using a different version of Unilogic to get online (other than the version used to program and download to PLC) gives not match error. I suggest you to use same versions on both computers. Quote Link to comment Share on other sites More sharing options...
Saragani Posted August 21, 2022 Report Share Posted August 21, 2022 It looks like a communication problem with the PLC. Both errors suggests that UniLogic was unable to fully communicate with the PLC, and I would suggest to check that port 22 isn't blocked somehow.

The problem computer is managed by an IT department. I'll send an inquiry to them. Quote Link to comment Share on other sites More sharing options...
