This object is always visible so that the status of the Light Controller is always available.
This object is useful particularly if the device does not function as required. It indicates
the possible causes:
Telegram value: Bit 0 = additional functions (Light control, staircase light or slave
Bit 1 = Block function is active 1 or inactive 0
Bit 2 = Forced operation is active 1 or inactive 0
Bits not used can be defined with the value 0.
A detailed assignment of the object value for the status byte is listed in the Annex.
The object value is sent with a change, download and reset.
Bit 0 always has the value 1 (active), if one of the three additional functions, Light control,
Staircase light function of slave mode is activated. The three additional functions can not be
enabled simultaneously for an output of the Light Controller. Bit 0 then has the value 1 if the
slave and control modes are in standby mode after an OFF command.
Note
The state of the additional function (staircase light operates, Light Controller
controls or the slave does not contain a brightness value from the master)
is indicated in the object Status function (No. 3).
