Scaling |
Gain/Offset |
The value of the monitored variable will be displayed in
a scaled manner. The following is the scaling formula.
DisplayedValue = MonitoredValue * Gain + Offset
If the option is selected, the entered value will be
scaled by the following formula with the same
coefficients (Gain and Offset) before it is output.
OutputValue = (EnteredValue – Offset) / Gain
Select and set this option in the Advanced page.
Note: The Gain and Offset are 32-bit
floating point numbers. They have, at most, 6
significant digits. Rounding and truncation errors may
occur. |
|
Max./Min. |
Set the Display Min/Max corresponding to the Data
Min/Max. If this option is selected, the value of the
monitored variable will be scaled to fit the display
range before displayed. And the entered value will be
scaled to fit the data range before it is output. |
|
Range Check |
Numeric entry will verify an entered value according to
the specified maximum and minimum. If the entered value
is not within the allowable range, the value will not be
output. Select and set this option in the Advanced page.
Note 1: When the scaling option is
selected, the output value is verified instead of the
entered value.
OutputValue = (EnteredValue – Offset) / Gain
Note 2: When the scaling option is
selected, the allowable maximum and minimum shown on the
numeric keypad are the scaled versions of the specified
maximum and minimum.
ScaledMaximum = Maximum * Gain + Offset
ScaledMinimum = Minimum * Gain + Offset |
