Table 12:
Priority object
Note:
4 different values can be sent with the telegram. So-called
priority objects can thus be addressed in the EIB devices. If a
channel e.g. in a switch actuator should switch on or off, the
value 1 or 0 is sent to the assigned switch object. If a priority
object is also assigned to this channel, the value that was sent
to the priority object defines the behaviour of the channel.
