Definitions Parameters
The structure of a device parameter in the Manufacturer Tool is as follows:
ParameterRefRef → ParameterRef → Parameter
| Parameter | is the actual parameter as it is stored in memory. It can have more than one associated ParameterRef, regardless of the target version |
| ParameterRef |
refers directly to Parameter, it offers the possibility to override values and properties. E.g. A parameter linked to a particular rocker might need different default values when set up for switching or dimming |
| ParameterRefRef | refers directly to ParameterRef and is the resource that will be used to visualize ‘Parameter’ in the ETS parameter dialog. ParameterRefRef is automatically created when its associated ParameterRef is added to the dynamic structure of the application program. |
Definitions ComObject
The structure of a group object in the Manufacturer Tool is as follows:
ComObjectRefRef → ComObjectRef → ComObject
Note: In the Manufacturer Tool, the term Communication object is used for Group objects.
| ComObject | is the actual communication object as it 'resides' inside the device. It can have more than one associated ComObjectRef, regardless of the target version. |
| ComObjectRef |
refers directly to ComObject, it offers the possibility to override properties E.g. a particular communication object could need, depending on the situation, different Datapoint Types |
| ComObjectRefRef | refers directly to ComObjectRef and is the resource that will be used to visualize the ComObject in the ETS device detail dialog. It is automatically created when its associated ComObjectRef is added to the dynamic structure of the application program. |
Example parameter structure and group object
The following example shows you how to create one parameter and one group object in ETS. It should be possible to increment the value of this parameter by using the arrows within the text field, or by simply changing the value in the text field. The default value of this parameter shall be set to 50d.
