Text description (identifier) of the error
Note to the error
The number of already upraised errors with the specified identifier.
If an error occurs in the application, then the error is captured and treated so as the application could run further. The error is written into the INFO system
and the onAppError
event is triggered. In this event it is possible to call, for example, the alarm
or other actions according to the designer requirements.
At script errors only the first rise of the error
is captured (only if pEvent.Counter
equals 1) to prevent endless loop if the error founds itself in the script of the onAppError
