4.2 List of faults and alarms
F01946 (A) PROFIBUS: Connection to the Publisher aborted
Message class: Communication error to the higher-level control system (9)
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The connection to at least one Publisher for PROFIBUS peer-to-peer data transfer in cyclic operation has been
aborted.
Fault value (r0949, interpret binary):
Bit 0 = 1: Publisher with address in r2077[0], connection aborted.
...
Bit 15 = 1: Publisher with address in r2077[15], connection aborted.
Remedy: - check the PROFIBUS cables.
- check the state of the Publisher that has the aborted connection.

A02050 Trace: Start not possible
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: The trace has already been started.
Remedy: Stop the trace and, if necessary, start again.
A02051 Trace: recording not possible as a result of know-how protection
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: TRACE recording is not possible as at least one signal or trigger signal being used is under know-how protection.
Alarm value (r2124, interpret decimal):
1: Recorder 0
2: Recorder 1
3: Recorders 0 and 1
Remedy: - Temporarily activate or deactivate know-how protection (p7766).
- include the signal in the OEM exception list (p7763, p7764).
- Where relevant do not record the signal.

A02055 Trace: Recording time too short
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: The trace duration is too short.
The minimum is twice the value of the trace clock cycle.
Remedy: Check the selected recording time and, if necessary, adjust.
A02056 Trace: Recording cycle too short
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: The selected recording clock cycle is lower than the basic clock cycle 500µs.
Remedy: Increase the value for the trace cycle.
