Variable Data type Function
rInput Input signal
rInputLowerLimit Lower limit of the input range
rInputUpperLimit Upper limit of the input range
rOutputLowerLimit Output value assigned to the upper limit of the input range (can
be lower than rOutputLowerLimit)
rOutputUpperLimit Output value assigned to the lower limit of the input range (can
be higher than rOutputUpperLimit)
Output variable
REAL
Scaled output signal
Description
This instruction scales a REAL value between a lower and an upper limit to a REAL output value.
Use WITHIN_LIMITS (see page 111) to check if the input value is within the specified limits.
Data types
Example
In this example the function has been programmed in ladder diagram (LD) and structured text (ST).
