4 Faults and alarms
4.2 List of faults and alarms
A01900 (F) PROFIBUS: Configuration telegram error
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: A PROFIBUS master attempts to establish a connection using an incorrect configuring telegram.
Alarm value (r2124, interpret decimal):
2: Too many PZD data words for input or output. The number of possible PZD is specified by the number of indices in
r2050/p2051.
3: Uneven number of bytes for input or output.
211: Unknown parameterizing block.
501: PROFIsafe parameter error (e.g. F_dest).
502: PROFIsafe telegram does not match.
Additional values:
Only for internal Siemens troubleshooting.
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: 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.
