• The SNVT_switch input data point is defined by a element that has a “Dp
Type” attribute of “input”. The input data point referenced by must have a
property of #0000000000000000[0]. SNVT_switch and a
property of Input0.
• The SNVT_lev_disc output data point to be translated is defined by a element that
have a “Dp Type” attribute of “Output”. The output data point referenced by must
have a of #0000000000000000[0]. SNVT_lev_disc and a
of Output0.
Each time a type translation is made, the SNVT_lev_desc output data point is assigned an enumeration
based on the current value and state stored in the SNVT_switch input data point, as described in the
following table:
SNVT_switch (input point) SNVT_lev_desc (output point)
value: any
state: 0 ST_NUL
value: 0.0
state: 1 ST_OFF
value: 0.1–25.0
state: 1 ST_LOW
value: 25.0–50.0
state: 1 ST_MED
value: 50.0–75.0
state: 1 ST_HIGH
value: 75.0–100.0
state: 1 ST_ON
value: >100.0
state: 1 ST_NUL
The following code demonstrates how to use the Set function to create a type translator that uses this
:
xsi:type="UFPTtypeTranslator_Cfg">
Net/LON/iLON App/Type Translator[11]
dpType="Input">
Net/LON/iLON App/VirtFb/nviSwitch
#0000000000000000[0].SNVT_switch
Input0
dpType="Output">
Net/LON/iLON App/VirtFb/nvolevDisc
#0000000000000000[0].SNVT_lev_disc
Output0
SNVT_switch_TO_SNVT_lev_disc
0
12.3.5 Using the Delete Function on a Type Translator
You can use the Delete function to delete a Type Translator. To delete a Type Translator, you provide
an element with a UFPTtypeTranslator_Cfg type that includes the property of
the type translator to be deleted. The following code sample demonstrates how to use the Delete
function to delete a Type Translator:
