4 Faults and alarms
4.2 List of faults and alarms
SINAMICS G120 Control Units CU240B-2/CU240E-2
814 List Manual (LH11), 01/2016, A5E33839529
Remedy: Check the bus configuration on the master and slave sides.
For alarm value = 2:
Check the number of data words for input and output.
For alarm value = 211:
Ensure offline version <= online version.
For alarm value = 501:
Check the set PROFIsafe address (p9610).
For alarm value = 502:
Check the enable of F-DI (p9501.30).
F01910 (N, A) Fieldbus interface setpoint timeout
Message class: Communication error to the higher-level control system (9)
Reaction: OFF3 (IASC/DCBRK, NONE, OFF1, OFF2, STOP2)
Acknowledge: IMMEDIATELY
Cause: The reception of setpoints from the fieldbus interface has been interrupted.
- bus connection interrupted.
- communication partner switched off.
For PROFIBUS:
- PROFIBUS master set into the STOP state.
See also: p2040 (Fieldbus interface monitoring time), p2047 (PROFIBUS additional monitoring time)
Remedy: Ensure bus connection has been established and switch on communication partner.
- if required, adapt p2040.
For PROFIBUS:
- set the PROFIBUS master to the RUN state.
- if the error is repeated, check the set response monitoring in the bus configuration (HW Config).
- slave redundancy: For operation on a Y link, it must be ensured that "DP alarm mode = DPV1" is set in the slave
parameterization.
A01920 (F) PROFIBUS: Interruption cyclic connection
Message class: Communication error to the higher-level control system (9)
Reaction: NONE
Acknowledge: NONE
Cause: The cyclic connection to the PROFIBUS master is interrupted.
Remedy: Establish the PROFIBUS connection and activate the PROFIBUS master in the cyclic mode.
Note:
If there is no communication to a higher-level control system, then p2030 should be set = 0 to suppress this
message.

A01945 PROFIBUS: Connection to the Publisher failed
Message class: Communication error to the higher-level control system (9)
Reaction: NONE
Acknowledge: NONE
Cause: For PROFIBUS peer-to-peer data transfer, the connection to at least one Publisher has failed.
Alarm value (r2124, interpret binary):
Bit 0 = 1: Publisher with address in r2077[0], connection failed.
...
Bit 15 = 1: Publisher with address in r2077[15], connection failed.
Remedy: Check the PROFIBUS cables.
