Communication PROFIBUS DP/PROFINET IO 10.2 Communication via PROFIBUS DP

For diagnostic purposes, there are the diagnostic parameters r2075 ("PROFIBUS diagnostics, receive telegram offset PZD") and r2076 ("PROFIBUS diagnostics, transmit telegram offset PZD"). The parameter r2074 ("PROFIBUS diagnostics, receive bus address PZD") displays the DP address of the setpoint source of the respective PZD.

r2074 and r2075 enable the source of a slave-to-slave communication relationship to be verified in the Subscriber.

Note

The Subscribers do not monitor the existence of an isochronous Publisher sign of life.

Alarms and error messages with PROFIBUS slave-to-slave communication

An alarm A1945 signals that a publisher of a device (CU320) is missing or has failed. Any interruption to the Publisher is also reported by an error F1946 at the affected DO. A failure of the Publisher will therefore only affect the respective DOs.
