No. Function
0 In operation
In order to regularly monitor the presence of the Light Controller on the KNX, a monitoring
telegram can be sent cyclically on the KNX. The communication object is enabled, if the
parameter Send object "in operation" in the parameter window General is set to send.
The send value of the telegram can be parameterised.
In the parameter window General you can parameterise if and at which intervals a telegram
with the value 1 or 0 is sent via the In operation object.
3 Status function
This object is always visible so that the state of the additional functions Light control,
Staircase light and Slave mode can always by queried, see
The status refers to the state of the additional functions, i.e. is the staircase lighting time
running, is the light controller running or does the slave receive a brightness value via
the object Brightness value of slave.
The state does not initially have anything to do with the activation of the additional functions
via the object Activate xy (xy = light control, slave mode for light control or staircase lighting
time).
This state is indicated in the first bit of the status byte object (No. 34, 59, 84, 109). An output
can only change a state (runs, control) when the additional function is activated.
Every bit defines the state of an output. The first bit belongs to output A, the second bit to
output B. For the four-fold Light Controller the third and fourth bits define the states of
outputs C and D:
Telegram value: 0 =
1 = Control controls, staircase light runs, slave mode operates.
For further information see:
Note
If forced operation is activated when an additional function is operational,
e.g. Permanent ON with staircase light, this forced operation is carried out.
The normal operation continues to run in the background so that the output
reassumes its previous function immediately after switch off of the forced
operation. For this reason the respective function of the object Status
function remains 1 (running). Only when the additional function has really
been completed is it possible to set the respective bit in the object Status
function to 0 (not running).
The information regarding if the additional function is actually active can be
queried via the first bit of the status byte of the output, or directly via the
respective object Activate xy (xy = light control, slave mode for light control
or staircase lighting time). If the additional function is deactivated (by sending
of a 0 to the object activate xy), the respective bit of the object Status
function is automatically 0.
