Select whether delays can be set via objects and specify the
switching delays
. By set-
ting a
blocking time
after switch-off, you prevent sensors from recognising a swit-
ched-off lamp in their detection zone as a temperature change, and sending a motion
message.
The blocking time begins once the master output has transmitted the value for "end of
motion", e.g. the command "light off" or a central off command is received. During this
time period, the master detects no motion, and the motion detection of the slaves is
not recorded. After the end of the time period, the master transmits the slave cycle re-
set telegram.
Application example:
Depending on the installation situation and lamps, it is possible that a detector will de-
tect the thermal change in the lamp when the light is switched off by the master as a
motion. Without a blocking time, the light would be switched on again immediately.
Set the master's output
sending pattern
.
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.
