Getting started
3.6 Use the CALCULATE instruction for a complex mathematical equation
Easy Book
46 Manual, 03/2014, A5E02486774-AF
Where:
Out
value
(Out)
Scaled output value
In
value
(in1)
Analog input value
In
high
(in2)
Upper limit for the scaled input value
In
low
(in3)
Lower limit for the scaled input value
Out
high
(in4)
Upper limit for the scaled output value
Out
low
(in5)
Lower limit for the scaled output value
In the "Edit Calculate" box, enter the equation with the parameter names:
OUT = ((in4 - in5) / (in2 - in3)) * (in1 - in3) + in5
When you click "OK", the Calculate
instruction creates the inputs
required for the instruction.
Enter the tag n
ames for the values
that correspond to the parameters.
