This parameter is used to select which object value is sent. The priority
control function is explained in the following table:
Bit 1 Bit 0 Access Description

The priority object has enabled e.g. the switch actuator.
The output switches depending on the value of the switch object.
1 0 OFF The priority object has switched e.g. the switch actuator OFF with
priority control. The switch object has no function.
1 1 ON The priority object has switched e.g. the switch actuator ON with
priority control. The switch object has no function.
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.
