Remedy: Restore the bus connection and set the controller to RUN.
PROFIBUS slave redundancy:
For operation on a Y link, it must be ensured that "DP alarm mode = DPV1" is set in the slave parameterization.

F01911 (N, A) PB/PN clock cycle synchronous operation clock cycle failure
Message value: -
Drive object: All objects
Reaction: OFF1 (OFF3)
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).

F01912 (N, A) PB/PN clock cycle synchronous operation sign-of-life failure
Message value: -
Drive object: All objects
Reaction: OFF1 (OFF3)
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 trig-
ger 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).

F01915 (N, A) PB/PN clock cycle synchronous operation sign-of-life failure drive object 1
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: Group display for problems with the sign-of-life of the master (clock-cycle synchronous operation) on the drive object
1 (Control Unit).
For central measurements, synchronism with the central master is lost.
