10 Monitoring
10.1 Permanent interruption of PROFIBUS communication
If the PROFIBUS communication is interrupted permanently, e.g. by cable breakage or
failure of the PROFIBUS master, no process data are transmitted to the slave being in the
"Data_Exchange" state.
After the watchdog monitoring time determined by the PROFIBUS master has expired, the
response parameterised in C13880/1
is executed.
The process data handling depends on the setting in C13885
. (The last data sent by the
master can either be used or set to zero.)
Preconditions for a controller (slave) response
 A monitoring time of 1 ... 65534 ms is set for the "Data_Exchange" state (C13881
).
A value of "65535 ms" (Lenze setting) deactivates the monitoring.
 A response is set for the slave in C13880/1
(Lenze setting: "No response").
 The slave is in the "Data_Exchange" state.
 The watchdog monitoring time is configured correctly in the master.
If one of these preconditions is not met, the response to the absence of cyclic process data
telegrams from the master is not executed.
