Engineering Units Conversions...

Creates conversion functions for converting between hardware raw values and physical engineering unit values. These functions can be selected in the Analog Points dialog to specify how to do these conversions when values are read from or written to hardware.

Conversions Table

List of all the conversion functions in the Current RTDB. Click on a function to select it for editing, deletion, or copying.

Delete

Deletes the conversion function selected in the conversions table. This button is enabled only if a conversion function is selected in the conversions table.

Copy

Creates a copy of the conversion function selected in the conversions table. A unique name based on the original conversion function name will be created for the new conversion function. This button is enabled only if a conversion function is selected in the conversions table.

New

Creates a new conversion function. A unique name will be created for the new conversion function.

Current RTDB

Name of the real-time database currently loaded for editing. See New/Select RTDB....

Apply

Commits all pending edits to the real-time host. See Apply .

Cancel

Discards all pending edits.

Settings

Name

Name of the selected conversion function in the conversions table. Rename the conversion function by simply typing in a new name.

Unit

Name of the engineering unit; for example, kilograms, volts, furlongs, or amps.

Direction

Direction of the conversion between raw and engineering units.

Raw to Physical

Converts raw hardware units to physical engineering units.

Physical to Raw

Converts physical engineering units to raw hardware units.

Conversion

Type of the selected conversion function. The frame to the far right will change to present the value to fill in for the selected conversion function type.

Table w/Interpola­tion

Conversion is specified by a lookup table. Results for input values that come between values in the first column are calculated via linear interpolation of values in the second column.  Up to twenty pairs of values may be specified.

Table w/o Interpola­tion

Conversion is specified by a lookup table. Results for input values that come between values in the first column are calculated by selecting the value in the second column corresponding to the next lower value in the first column. That is, lookup is done without doing interpolation. Up to twenty pairs of values may be specified.

Quadratic Function

Conversion is specified by a quadratic equation: .

Rational Function

Conversion is specified by the ratio of two quadratic equations:
