For invalid values, termination is performed from FB “LHcs4x00_Diag82” via
RETURN.
For POM errors, the channel number is calculated in the diagnostic buffer.
At an incoming event, the error information in the “diag” buffer of the respective
HCS is written in DB “LHcs4x00_Get” and the error information deleted at the
outgoing event.
