Instruction Manual

The 16 SNVT_switch data points to be translated are defined by a list of <InDataPoint>
elements. Each element must contain two properties: <UCPTpointName> and
<UCPTindex>. The <UCPTpointName> must identify a SNVT_switch data point. The
<UCPTindex> must be in the range 0-15.
The value of the state field of each input data points will be read and stored in bitX of the
output data point, where X represents the <UCPTindex> selected for the input data point.
For example, the state field of the data point assigned index number 0 in the Type Translator
would be stored in Bit0 of the output SNVT_state data point. Or, the state field of the data
point assigned index number 8 would be stored in Bit7 of the output SNVT_state data point.
If any of the index numbers for the input data points are not used (meaning that less than 16
data points were supplied to the Type Translator), then the corresponding field in the output
data point will be assigned a value of 0.
12.2.1.2.1.2 SNVT_lev_disc_TO_SNVT_occupancy
Use this Type Translator Rule to translate an input data point of type SNVT_lev_disc to an
output data point of type SNVT_occupancy. When you use this rule, you must reference the
SNVT_lev_disc data point that is to be translated by its <UCPTpointName> in the
<InDataPoint> element. You must reference the SNVT_occupancy data point to store the
result of the translation by its <UCPTpointName> in the <OutDataPoint> element.
Each time a type translation is made, the Type Translator will assign the SNVT_occupancy
output data point an enumeration value based on the enumeration assigned to the input
data point. The enumeration values assigned to the output data point follow the rules
described in Table 62.
Table 62 SNVT_lev_disc_TO_SNVT_occupancy
If the Input SNVT_lev_disc Data Point Is..... Then the SNVT_occupancy Output Data
Point Will Be Set To...
ST_NUL OC_NUL
ST_OFF OC_UNOCCUPIED
ST_ON OC_OCCUPIED
ST_HIGH OC_BYPASS
ST_LOW OC_STANDY
ST_MED OC_STANDY
12.2.1.2.1.3 SNVT_lev_disc_TO_SNVT_switch
Use this Type Translator Rule to translate an input data point of type SNVT_lev_disc to an
output data point of type SNVT_switch. When you use this rule, you must reference the
SNVT_lev_disc 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.
Each time a translation is made, the Type Translator will assign the SNVT_switch output
data point a value that is based on the enumeration currently assigned to the input data
point. The values assigned to the output data point follow the rules described in Table 63.
