Scale UINT data to INT data
This instruction scales an unsigned INTEGER value between a lower and an upper limit to an INTEGER output value. Use WITHIN_LIMITS to check if the input value is within the specified limits.
Input
Input signal
Lower limit of the input range
Upper limit of the input range
Output value assigned to the lower limit of the input range (can be higher than iOutputUpperLimit)
Output value assigned to the upper limit of the input range (can be lower than iOutputLowerLimit)
Output
Scaled output signal
All input and output variables used for programming this function have been declared in the POU header. The same POU header is used for all programming languages.
