Object_Name
The name of the parameter with the name of the Analog Output as a prefix.
Object_Type
ANALOG VALUE (2).
Present_Value
The value of the parameter.
Colour_Temp
The colour temperature in Kelvin (K).
Same value as the property Colour_Temp of the associated Analog Output object.

The colour temperature in 1 Mirek.
Same value as the property Colour_TC_TC of the associated Analog Output object.
Description
A description of the object.
Status_Flags
This property indicates the general "reliability" of the object.
Reliability
This property indicates whether the operation of the object is reliable. The values are as follows:
- NO_FAULT_DETECTED (0) - No fault has been detected.
Out_Of_Service
It indicates whether the algorithm that the object represents is in service.
Units, Min_Pres_Value, Max_Pres_Value, Resolution
The Units, Min_Pres_Value, Max_Pres_Value and Resolution for the Present_Value.
