Bit assignment: Data byte: toggle bit/NMT status
The monitoring time for the master's requests can be parametrised. Monitoring begins with the first
received remote request of the master. From this time on, the remote requests must arrive before the
set monitoring time has passed.
The toggle bit is reset through the NMT command “Reset communication”. It is therefore not set in the
first response of the EMCA.
Calculate cyclical monitoring time (Life time)
The max. time period between 2 remote queries is defined through the cyclical monitoring time.
The cyclical monitoring time for Node guarding is calculated as follows:
Lifetime
+
Guardtime(100C
h
) * Lifetimefactor(100D
h
)
D.8.8
Object 100Ch: Monitoring time (Guard time)
Through the object “Guard time”, the time value [ms] is specified for the cyclical monitoring time Life
time.
