Pb/Pn Clock Cycle Signal Error When Establishing Bus Communication; If1: Pb/Pn Sign-Of-Life Synchronism Not Reached; Pb/Pn Clock Cycle Synchronous Operation Synchronization Unsuccessful - Siemens Sinamics S120 Diagnostic Manual

201943 <location>IF1: PB/PN clock cycle signal error when establishing bus communication
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The bus is in the data exchange state and clock synchronous operation has been selected using the parameterizing
telegram. The global control telegram for synchronization is being irregularly received.
-.the master is sending an irregular global control telegram.
- the master is using another clock synchronous DP clock cycle than was transferred to the slave in the parameterizing
telegram.
Remedy: - check the master application and bus configuration.
- check the consistency between the clock cycle input when configuring the slave and clock cycle setting at the master.

201944 <location>IF1: PB/PN sign-of-life synchronism not reached
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The bus is in the data exchange state and clock synchronous operation has been selected using the parameterizing
telegram. Synchronization with the master sign-of-life (STW2.12 ... STW2.15) could not be completed because the
sign-of-life is changing differently to how it was configured in the Tmapc time grid.
Remedy: - ensure that the master correctly increments the sign-of-life in the master application clock cycle Tmapc.
- correct the interconnection of the master sign-of-life (p2045).

201950 <location>IF1: PB/PN clock cycle synchronous operation synchronization
unsuccessful
Message value: -
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: Only for internal Siemens troubleshooting.
