NOTE!
Internal and external errors of the PROFIBUS-DP interface are classified as fault and are
used to generate the "system fault" signal (collective fault). In addition, the errors are entered
in the event list of the central processing unit.
CAUTION!
In case of an external fault (e. g. interface cable disconnected), the last received value is re-
tained.
Thus, there is a risk that the used value is out of date.
Therefore, it is necessary to evaluate the status of the "fieldbus error" signal. Therefore, it is
necessary to evaluate the status of the "fieldbus error" signal. This allows to set outputs to a
safe state by the PLC if applicable.
