if this happens I go to --> Build --> Generate code then there exists a IDE Code and a PLC/API code and comparison before download is possible. Give it a try?

Thanks alot for your time and help! I quickly tested the suggestion, as it makes a lot of sense. Unfortunately the erros still appear as before. The settings was already set before, and i tried turning it off.. no effect..

Post by julianramirez on Codesys Trend - setting Y axis minimum and maximum as variables - error ^{CODESYS Forge talk (Post)}
Hello Hannibal, I am using real vars and it works, however, if I update those vars in real time it doesnt quite change it on y axis, do you think it is because it is not an integer?

Post by ewi04 on Git - User identification data is lost when codesys is closed ^{CODESYS Forge talk (Post)}
Hallo, it's not a big problem, but it is a bit annoying. The git user identification data is lost when codesys is closed. So I have to enter the information again and again. Is there a way to save the data? Environment: Codesys V3.5 SP19 Patch 4 (64Bit), Git 1.3.0.0 Thanks
