Engineering units scaling
The parameters Offset and Gain are used to change the scale of the controller value to
a value shown in accordance with the following equation.
Panel value = Offset+Gain*Controller value
When the value for an object is changed from the operator panel, the scale is changed
to the value shown in accordance with the following equation:
Controller value = (Panel value-Offset)/Gain
Scaling does not affect the defined maximum and minimum values, or the number
of decimal places.
Offset Gain Calculation
The function Offset Gain calculation is a tool to calculate the offset and gain parame-
ters. Specify the value of Offset and Gain under the General tab for the object and click
on Calculate to display the following dialog.
Enter the range for the controller value and panel value. The correct values for the
parameters Offset and Gain are calculated.
