The following table shows the diagnostics information of the MFE fieldbus interface set
up for evaluation in the higher-level PLC application. The signals are transferred to the
controller via parameters and via the process data channel.
The logical communication status "0" signals the status "OK" for each signal. There-
fore, the asynchronously running start-up sequences of the PLC and the device do not
output any false diagnostic messages upon start-up of the system (bus start-up with
useful data= 0).
