SCP - Scale with Parameter

Produces a scaled output value that has a linear relationship between the input and scaled values. The scaled result is returned to the address indicated by the output parameter.

Example

Equation: Scale 4 - 20 ma to 0 - 100 % = F8:101

Ladder Logic Solution:

Convert 4 - 20 ma to 0 - 100 % signal.

Example

Equation: Scale 0 - 100 to 0 - 1000 = F8:101

Ladder Logic Solution

Convert a parameterized min / max to a scaled min / max

Note

If the scaled min = max, then the scaled output is forced to the scaled output min. If the input, input min, and input max are all equal, then the output = scaled output

min value. If the input min > input max, then the scaled output = scaled output min value. If the scaled min > scaled max, then the output = scaled output min value.
