DPPEVT
The DPPEV (DP process event) provides more detailed information
about the Profibus DP process alarm (OB40 alarm). Contrary to the
DPEVT, only selected information/data is available, but then, in a
conditioned form.
When an alarm event is output, all of the values at the outputs are
updated.
For a communications error, the cause is additionally output at YTS and
the QTS output is set to "0".
