4 Faults and alarms
4.2 List of faults and alarms
F01910 (N, A) Fieldbus: setpoint timeout
Message value: -
Message class: Communication error to the higher-level control system (9)
Drive object: All objects
Reaction: Vector: OFF3 (IASC/DCBRK, NONE, OFF1, OFF2, STOP2)
Infeed: OFF2 (NONE, OFF1)
Acknowledge: IMMEDIATELY
Cause: The reception of setpoints from the fieldbus interface (onboard, PROFIBUS/PROFINET/USS) has been interrupted.
- bus connection interrupted.
- controller switched off.
- controller set into the STOP state.
See also: p2040 (Fieldbus interface monitoring time), p2047 (PROFIBUS additional monitoring time)
Remedy: Restore the bus connection and set the controller to RUN.
Note regarding PROFIBUS slave redundancy:
For operation on a Y link, it must be ensured that "DP alarm mode = DPV1" is set in the slave parameterization.
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
F01911 (N, A) PB/PN clock cycle synchronous operation clock cycle failure
Message value: -
Message class: Communication error to the higher-level control system (9)
Drive object: All objects
Reaction: Vector: OFF1 (OFF3)
Infeed: OFF1
Acknowledge: IMMEDIATELY
Cause: The global control telegram to synchronize the clock cycles has failed - in cyclic operation - for several DP clock
cycles or has violated the time grid specified in the parameterizing telegram over several consecutive DP clock
cycles (refer to the bus cycle time, Tdp and Tpllw).
Remedy: - check the physical bus configuration (cable, connector, terminating resistor, shielding, etc.).
- check whether communication was briefly or permanently interrupted.
- check the bus and controller for utilization level (e.g. bus cycle time Tdp was set too short).
PB: PROFIBUS
PN: PROFINET
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
F01912 (N, A) PB/PN clock cycle synchronous operation sign-of-life failure
Message value: -
Message class: Communication error to the higher-level control system (9)
Drive object: B_INF, ENC, VECTOR_G
Reaction: Vector: OFF1 (OFF3)
Infeed: OFF1
Acknowledge: IMMEDIATELY
Cause: The maximum permissible number of errors in the controller sign-of-life (clock synchronous operation) has been
exceeded in cyclic operation.
Remedy: - physically check the bus (cables, connectors, terminating resistor, shielding, etc.).
- correct the interconnection of the controller sign-of-life (p2045).
- check whether the controller correctly sends the sign-of-life (e.g. create a trace with STW2.12 ... STW2.15 and
trigger signal ZSW1.3).
- check the permissible telegram failure rate (p0925).
- check the bus and controller for utilization level (e.g. bus cycle time Tdp was set too short).
