If faults occur during communication between the PROFIBUS and the
CBP, corresponding fault or alarm messages are displayed on the PMU
or on the OP of the basic unit.

A 081
A 089
The ID byte combinations sent by the DP master in the
configuration telegram do not correspond with the
permitted ID byte combinations (see table 8.2-12)
Consequence:
No connection established with the PROFIBUS-DP
master; new configuration is necessary.
A 082
A 090
No valid PPO type can be established from the
configuration telegram from the DP master.
Consequence:
No connection established with the PROFIBUS-DP
master, new configuration is necessary.
A 083
A 091
No net data or invalid net data (e.g. complete control
word STW1=0) are being received by the DP master.
Consequence:
The process data are not being transferred to the DPR.
If parameter P722 (P695) is not equal to zero, this will
result in fault message F 082 being tripped (see
chapter "Process data monitoring".
A 084
A 092
Telegram traffic between DP master and CBP has
been interrupted (e.g. cable break, bus connector
disconnected or DP master switched off).
Consequence:
If parameter P722 (P695) is not equal to zero, this will
result in fault message F 082 being tripped (see
chapter "Process data monitoring").
A 086
A 094
Failure of heartbeat counter recognized by basic unit.
Consequence:
Interruption of communication to the automation system
A 087
A 095
DP slave software detects serious fault. Fault number
in diagnostic parameter r732.8
Consequence:
Communication no longer possible. Secondary fault
