UnitsAdder
Summary Determines how the scaled value of the data point or monitor
point will be unit-converted for display as a formatted value
when your application reads the FormattedValue propery .
When your application reads the FormattedValue property of
a data point or monitor point, the OpenLNS Object Server
converts the scaled value of the data point or monitor point
so that it can be display as a formatted value.
To unit-convert the value, OpenLNS first multiplies it by the
value in the UnitsMultiplier property. It then adds the value
stored in the UnitsAdder property. The resulting value will
be appropriate for the units that apply to this format
specification.
Different data formats for the same data type will be on
different scales. For example, the SNVT_temp_f data type
contains the temperature in degrees Celcius. In order to
display the temperature in Fahrenheit, you would have to
multiply the value by 1.8 (9/5), and then add 32.
Availability Local, full, lightweight, and independent clients. Independent
clients can only access FormatSpec objects through monitor
points in permanent monitor sets.
Syntax units = fsObject.UnitsAdder
Element Description
