Scaling
Related information
Scaling affects only tags connected to a controller.
Checking the
Scaling
box displays the
Offset
and
Gain
columns. These parameters are used to change the scale of the controller value to a value shown in accordance with the following equation:
Panel value = Offset + (Gain * Register 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:
Register value = (Panel value - Offset)/Gain
Scaling does not affect the defined maximum and minimum values, or the number of decimals.
