I search through the program but could not found any errors. Someone have already a problem like this? Or know how to solve it? ------------------------------------------------------------------------------------------ Split from Compilation Error. Attachment Compile error.PNG (409 Downloads)

This should take you to the event where the function list has an error. Perhaps a required parameter for a function is missing. Kind regards Stefan

I will share some images as examples. Sorry about the Paint graphics :) Attachment Inconsistency1.png (26 Downloads)

To bypass this error, I made a copy of the screen which was linked by the compiler. I then erased the “faulty” screen and renamed the copied screen to its original name. This worked for me every time. Looks like a bug from TIA Portal for me.
	If it works, do not modify it!
