Siemens SIMATIC HMI series System Manual

The information on the currently processed action is also output again as OnErrorExecute.
Note
If no action is blocking the processing, no text file will be created and no OnErrorExecute will
be output.
Example
A "blocking" action can be simulated using the MessageBox(NULL, "Welt", "Hallo", MB_OK);
function.
The action which calls the error box is not resumed until the box has been closed. This is
comparable to a Message Box with a loop or a Sleep().
To check whether an action is blocking processing:
1. Start ...Siemens\WinCC\uTools\Apdiag.exe.
2.
Select "Info > FirstAction".
3. Enter the name of a text file in dialog "Save as".
The following information is then put in the text file:
WinCC diagnosis
6.3 ApDiag Menu Commands
