Monitoring: Telegram failure
Description
In monitoring for telegram failure, two cases are possible:
● Telegram failure with a bus fault
After a telegram failure and the additional monitoring time has elapsed (p2047), bit
r2043.0 is set to "1" and alarm A01920 is output. Binector output r2043.0 can be used for
an emergency stop, for example.
Once the delay time (p2044) has elapsed, fault F01910 is output.
Fault F01910 triggers fault response OFF2 (pulse inhibit) for the infeed and OFF3 (quick
stop) in the drive.
If no OFF response is to be triggered, the fault response can be reparameterized
accordingly.
Fault F01910 can be acknowledged immediately. The drive can then be operated even
without PROFIBUS.

● Telegram failure with a CPU stop
After telegram failure, bit r2043.0 is set to "1." Binector output r2043.0 can be used for an
emergency stop, for example.
Once the delay time (p2044) has elapsed, fault F01910 is output.
Fault F01910 triggers fault response OFF2 (pulse inhibit) for the infeed and OFF3 (quick
stop) in the drive.
If no OFF response is to be triggered, the fault response can be reparameterized
accordingly.
Fault F01910 can be acknowledged immediately. The drive can then be operated even
without PROFIBUS.
