often you will want to scale the analog input va

lues to a more

convenient engineering unit number range.

Scaling Analog Inputs

The scaling function block is used to convert the raw 0 to 4095

units of the analog input to an engineering unit number. The

result of this scaling conversion is usually stored in a shared

variable register that you define in the shared variable editor.

After scaling the analog input to a register, you can use the

process variable in engineering units.

An example of an analog scaling entry is shown in Figure

For more details about configuring analog scaling function

blocks refer to Using the Analog Scaling Editor in Section 5

Working with Programs and Function Blocks in the Regent

User’s Guide.
