PN: PROFINET
A01945 PROFIBUS: Connection to the Publisher faulted
Drive object: A_INF, B_INF, CU_LINK, CU_S, DMC20, SERVO, S_INF, TB30, TM15, TM15DI_DO, TM17, TM31, TM41,
TM54F_MA, TM54F_SL, VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: For PROFIBUS peer-to-peer data transfer, the connection to at least one Publisher is faulted.
Alarm value (r2124, interpret binary):
Bit 0 = 1: Publisher with address in r2077[0], connection faulted.
...
Bit 15 = 1: Publisher with address in r2077[15], connection faulted.
Remedy: - check the PROFIBUS cables.
- carry out a first commissioning of the Publisher that has the faulted connection.

F01946 (A) PROFIBUS: Connection to the Publisher interrupted
Drive object: A_INF, B_INF, CU_LINK, CU_S, DMC20, SERVO, S_INF, TB30, TM15, TM15DI_DO, TM17, TM31, TM41,
TM54F_MA, TM54F_SL, VECTOR
Reaction: A_INFEED: OFF1 (NONE, OFF2)
SERVO: OFF1 (NONE, OFF2, OFF3)
VECTOR: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: At this drive object, the connection to at least one Publisher for PROFIBUS peer-to-peer data transfer in cyclic oper-
ation was interrupted.
Alarm value (r2124, interpret binary):
Bit 0 = 1: Publisher with address in r2077[0], connection interrupted.
...
Bit 15 = 1: Publisher with address in r2077[15], connection interrupted.
Remedy: - check the PROFIBUS cables.
- check the state of the Publisher that has the interrupted connection.

Reaction upon A: NONE
Acknowl. upon A: NONE
F01950 (N, A) IF1: PB/PN clock cycle synchronous operation synchronization unsuccessful
Drive object: All objects
Reaction: OFF1 (NONE)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: Synchronization of the internal clock cycle to the global control telegram has failed. The internal clock cycle exhibits
an unexpected shift.
Remedy: Siemens internal
