CHAPTER 7 DISPLAYING AND INPUTTING DATA
7.1. Numeric Entries
You can enter a value and change the specified variable using a numeric entry.
7.1.1. Operation Options
The following operation options can be added to a numeric entry. Select and set up the options in the Numeric Entry
property sheet.
Options Description
Scaling 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. The rounding and truncation errors may happen.
Range Check The numeric entry will verify the 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 instead of the entered value is
verified.
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 version of the specified maximum and minimum.
ScaledMaximum = Maximum * Gain + Offset
ScaledMinimum = Minimum * Gain + Offset
