Faults and alarms
15.2 List of faults and alarms
Cause: The bus is in the data exchange state and clock synchronous operation has been selected using the parameterizing
telegram. It was not possible to synchronize to the clock cycle specified by the master.
- the master does not send a clock synchronous global control telegram although clock synchronous operation was selected
when configuring the bus.
- the master is using an isochronous DP clock cycle that is different than was transferred to the slave in the parameterizing
telegram.
- at least one drive object has a pulse enable (also not controlled from PROFINET).
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.
- check that no drive object has a pulse enable. Only enable the pulses after synchronizing the PROFINET drives.
Note:
PN: PROFINET
A01941 PN: Clock cycle signal missing when the bus is being established
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 not being received.
Remedy: Check the master application and bus configuration.
Note:
PN: PROFINET
A01943 PN: Clock cycle signal error when the bus is being established
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.
Note:
PN: PROFINET
A01944 PN: Sign-of-life synchronism not reached
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).
Note:
PN: PROFINET
F01950 PN: Clock synchronous operation, synchronization unsuccessful
Reaction: OFF1
Acknowledge: IMMEDIATELY
