Rectifier/Regenerating Unit Operating Instructions
Alarm A081
The identifier byte combinations transmitted by the DP master in the configuration telegram do not match
the permitted identifier byte combinations (configuring error on DP master)
Effect: No link can be established with the DP master, reconfiguration necessary.
Alarm A082
No valid PPO type can be determined from the configuration telegram from the DP master.
Effect: No link can be established with the DP master, reconfiguration necessary.
Alarm A083
No user data, or only invalid data, are being received from the DP master.
Effect: The process data are not transferred to the basic unit. When the telegram failure monitoring
function is active (P695 set to value other than 0), this disturbance generates fault message F082 with
fault value 10.
Alarm A084
The exchange of data between the communication board and DP master has been interrupted (e.g. cable
break, bus connector removed or DP master switched off).
Effect: When the telegram failure monitoring function is active (P695 set to value other than 0), this
disturbance generates fault message F082 with fault value 10
Alarm A085
Error in the DPS software of the communication board.
Effect: Fault message F081 is generated.
Alarm A086
Failure of heartbeat counter detected by SIMOVERT 6SE70.
Effect: Interruption in communication with PROFIBUS.
Alarm A087
DP slave software has detected serious fault, fault number in diagnostic parameter n731.08.
Effect: Total communication failure (secondary fault F082).
Alarm A088
At least 1 configurable internode transmitter is not yet active or has failed again (for details, see
diagnostic parameter n731).
Effect:If a transmitter is not yet active, the associated setpoints are set to "0" as an alternative. If an
internode transmitter fails again, transmission of the setpoints to the SIMOVERT 6SE70 may be
interrupted depending on the setting of P700 (with secondary fault F082).
