Communications Processor CP 541
EWA 4NEB 812 6188-02
Diagnostics offers you the facility for monitoring the proper functioning of
the CP 541 and evaluating any errors.
Information on incorrect operational states are stored by the CP 541 in diag-
nostics block DB2. If necessary, the CP 541 generates the DP diagnostics.
The CP 541 issues a diagnosis at different locations:
Locally with the LED indicators
In diagnostics block DB2
In a diagnostics message with a DP connection to the DP master
DP diagnostic report to the connected programmable controller
If an error occurs, the CP 541 always activates the LED indicator according
to the error, and enters the error code in DB2.
