12.3.4.7 SNVT_setting_TO_SNVT_switch
You can use this Type Translator Rule to translate an input data point of type SNVT_setting to an
output data point of type SNVT_switch.
• The SNVT_setting 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_setting 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.
Each time a type translation is made, the value and state fields of the SNVT_switch ouput data point
are assigned values based on the current values stored in the function and setting fields of the
SNVT_setting input data point, as described in the following table:
SNVT_setting (input point) SNVT_switch (ouput point)
function: SET_STATE
setting: <=100.0 value: 0.0
state: 0 (OFF)
function: SET_STATE
setting: >100.0 value: <=setting>
state: 0 (OFF)
function: SET_NUL
setting: any value: 0.0
state: 0 (OFF)
The following code demonstrates how to use the Set function to create a type translator that uses this
<UCPTtranslatorRule>:
