In addition, you can refer to a
slave signal
, i.e. a signal from an additional motion de-
tector, for controlling purposes.
The slave device periodically sends a 1 to the bus, as long as a motion is detected. The
master receives this at the input object "master: slave message" and evaluates the sla-
ve message as an own sensor message.
Furthermore, the master has the possibility of triggering a reset of the slave sending
cycle.
Information on setting the slave sending cycle and the cycle reset can
be found in chapter
Align communication between master and slave
Set the
object type and value
for the master's slave cycle reset output in the same
way, as the cycle reset input for the slave.
The master can be
blocked
via the bus.
5.6.2. Align communication between master and slave
Sending cycle slave - switch-off delay master
Set the slave's
sending cycle
shorter than the master's switch-off delay. Thereby it is
ensured that the master does not perform a switch-off action, while the slave is still de-
tecting a motion.
Slave cycle reset
The cycle reset for the slave is required, if a master switch action by the "master: central
off" object was triggered.
When the master performs a switch-off action, it simultaneously sends a message to
the bus via the "master: slave cycle reset". . This message can be received by the slave
