SIMOTRAS HD Operating Instructions
Alarm A082 (1
st
CB) or alarm A090 (2nd CB)
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 (1
st
CB) or alarm A091 (2
nd
CB)
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 (U722 set to value other than 0), this disturbance generates fault
message F082 with fault value 10.
Alarm A084 (1
st
CB) or alarm A092 (2
nd
CB)
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 (U722 set to value other than
0), this disturbance generates fault message F082 with fault value 10.
Alarm A085 (1
st
CB) or alarm A093 (2
nd
CB)
Error in the DPS software of the communication board.
Effect: Fault message F081 is generated.
Alarm A086 (1st CB) or alarm A094 (2
nd
CB)
Failure of heartbeat counter detected by SIMOTRAS HD master.
Effect: Interruption in communication with PROFIBUS.
Alarm A087 (1
st
CB) or alarm A095 (2
nd
CB)
DP slave software has detected serious fault, fault number in diagnostic parameter n732.08.
Effect: Total communication failure (secondary fault F082).
Alarm A088 (1
st
CB) or alarm A096 (2
nd

At least 1 configurable internode transmitter is not yet active or has failed again (for details,
see diagnostic parameter n732).
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
SIMOTRAS HD may be interrupted depending on the setting of U715 (with secondary fault
F082).
