Process control instructions
SCALE_UINT_INT
This instruction scales an unsigned INTEGER value between a lower and an upper limit to an
Description
INTEGER output value. Use WITHIN_LIMITS (see page 111) to check if the input value is within
the specified limits.

In this example the function has been programmed in ladder diagram (LD) and structured text (ST).
Example
The same POU header is used for all programming languages.
