Table 8.2-13 Interaction of P722 / P695 and response monitoring (watchdog)
Always set parameter P722 / P695 to the value of 10 for operation with
the CBP. Monitoring of process data is thus activated/deactivated by the
value of the response monitoring time solely by the PROFIBUS-DP
master! The converter monitors the entering of process data in the dual-
port RAM from the instant at which the CBP enters valid process data in
the dual-port RAM for the first time. Fault F082 can only be tripped after
this instant!
Process data whose complete control word (PZD1) has the value zero is
not passed on to the dual-port RAM by the CBP (alarm A083)! From
MASTERDRIVES MC V1.62 with CBP2 V>=2.21 and standard telegram
5 (PROFIdrive Profile V3 with equidistance) onwards, the process data
can be transferred to the dual-port RAM irrespective of the content of the
control word.
