Hello nagadevan

What do you use WinCC comfort/Advanced or WInCC Professional Runtime?

Which Version?

What happens when you do a doubleclick on the Error Message, which Script or Editor opens?

Post your Script that do not work?

Bye Murof

i get as the error goto function has been deleted or disables.

Hello nagadevan.k,

please check if two alarm classes have the same ID number.
(See "HMI Alarms > Alarm classes > Properties > General > General > ID".)
This shouldn't  happen, but that's what I read in the error message.

There might be a little inconsistency in the project.

• Please close it, open the project folder and delete the "IM" folder". It contains only temporary files and deleting them is a bit stronger than to "rebuild all". Old temporary files can cause problems.
• Open the project an compile it. This builds a new IM folder. Does the error still show up?

Hey

This solution solved so many of my compilation problems with TIA v13 WinCC. Thank you very very much! 

It solved: 

• Compilation error: "Internal error: "recipe without 3 string relations""
• My screen in the runtime suddenly behaved much different then i designed it (buttons flashing that shouldn't flash, colors messed up, ..). My whole project was pretty much unusable. Just by removing the "IM" folder in the project folder it recovered and compiled/works as it should.

You are a lifesaver.
