How to debugging a Visu Exception if there is an Visu exception shown in the Visualization:

Step-by-step guide

Use the following Option:

  1.  Execute Tools -> Customize - 'Add command..' -  Category „Online“  - Stop execution on handled exception

When the error occurs from one of the CODESYS visualization elements, this then must be investigated.
