SIMOVERT MASTERDRIVES
Please note the different parameter numbers for the types of unit with the
older function classes FC (CU1), VC (CU2) and SC (CU3).
In order to make these differences clear, these parameter numbers are
either printed in dark gray or have a dark-gray background.
P722.x (CB/TB TlgOFF)
With parameter P722. / P695, you can determine whether entering of process
data into the dual-port RAM by the CBP is to be monitored by the converter.
For parameter P722
Index 1 is applicable for the first CBP and
Index 2 is applicable for the second CBP.
To determine which CBP is the first one and which is the second one, see
section 8.2.5 "Mounting methods / CBP slots".
If process data monitoring has been activated, a fault in the DP master is
followed by a reaction of the converter, irrespective of the reply-
monitoring time in the CBP.

monitor t
WD
When the DP master is being configured, it is specified whether telegram
traffic with the master is to be monitored by the slave (CBP). If response-
monitoring is active, the PROFIBUS-DP master passes on a time value
t
(watchdog time) to the Slave when a connection is made.
WD
If the response-monitoring time expires, the CBP ceases to write process
data into the dual-port RAM. When this is combined with P722.x / P695,
it is therefore possible to plan your process data monitoring.
