The following code demonstrates how to use the Set function to create a type translator that uses this

12.3.4.6 SNVT_scene_TO_SNVT_switch
You can use this Type Translator Rule to translate an input data point of type SNVT_scene to an
output data point of type SNVT_switch.
• The SNVT_scene input data point is defined by a <DataPointFormat> element that has a “Dp
Type” attribute of “Input”. The input data point referenced by <UCPTname> must have a
<UCPTformatDescription> property of #0000000000000000[0]. SNVT_scene and a
<UCPTnickName> property of Input0.
• The SNVT_switch output data point to be translated is defined by a <DataPoint> element that
have a “Dp Type” attribute of “Output”. The output data point referenced by <UCPTname> must
have a <UCPTformatDescription> of #0000000000000000[0]. SNVT_switch and a
<UCPTnickName> of Output0.
You can use this Type Translator Rule to translate an input data point of type SNVT_scene to an
output data point of type SNVT_switch. When you use this rule, you must reference the SNVT_scene
data point that is to be translated by its <UCPTpointName> in the <InDataPoint> element. You must
reference the SNVT_switch data point to store the result of the translation by its <UCPTpointName>
in the <OutDataPoint> element.
