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:

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

Telegram traffic between DP master and CBP has
A 084 A 092
been interrupted (e.g. cable break, bus connector
disconnected or DP master switched off).
