Inputs
|
Input |
Data type |
Description |
|
IN |
REAL |
Real value. |
|
IMIN |
REAL |
Minimum input value. |
|
IMAX |
REAL |
Minimum input value. |
|
OMIN |
REAL |

Result: OMIN + IN * (OMAX - OMIN) / (IMAX - IMIN). |
Truth table
|
Inputs |
OUT |
|
IMIN >= IMAX |
= IN |
|
IN < IMIN |
= OMIN |
|
IN > IMAX |
= OMAX |
|
other |
= OMIN + IN * (OMAX - OMIN) / (IMAX - IMIN) |
Remarks
In LD language, the operation is executed only if the input rung (EN) is TRUE. The output rung (ENO) keeps the same value as the input rung.
ST Language
OUT := ScaleLin (IN, IMIN, IMAX, OMIN, OMAX);
FBD Language
LD Language
The function is executed only if EN is TRUE.
ENO keeps the same value as EN.
