Start

Description
Use menu command "Start" to open a dialog, in which a diagnostics level can be selected.
Select the "OK" button to start the diagnosis and write the trace point in the defined level.
The higher the level, the more frequent and less serious the trace points are.
In level 1, only faults are output, as of level 3, printf (OnErrorExecute) are output as well. Levels
9 and 10 are mainly for testing for whether the script.exe application reacts.
In chapter "Trace points and their diagnostics level), a selection of trace points is described.
The diagnosis is different from the "printf information" in that the entries are collected with the
window closed as well and mainly system messages (trace points) are shown.
Other trace entries can also be created using internal functions TraceTime() and TraceText().
The functions are described in the WinCC Help.
The trace entries are output in the diagnostics window as standard.
Note
End ApDiag
The diagnosis is switched off when changing projects and when ending ApDiag.
The option "Start automatically at WinCC start" offers the ability to start the diagnosis in the
defined level automatically, each time a project is opened.
