Go to the [Numeric Data] tab.
Data Format: Sets the data format corresponding to data contained in specified word address
and 7 types are available.
Max/Min Value Setting: Setting the range of input available value.
Over Max/Under Min: Specifying color of the value displayed when it exceeds the Max or the
Min of the value.
Flash: When the value of the specified word address is greater than the Max or less than the
Min, the value of the component will be flashed to make the transfinite alarm more
visible.
Proportional Conversion: The value of the specified word address will be converted
according to the settings and displayed on number input
component. To select this function, [Min Value] and [Max Value]
must be set.
For example: it is assumed that the original data is represented by “A” and the displayed data
by “B”, then the data B can be obtained by the following conversion formula:
B = [Minimum Proportional Value] + (A - [Minimum Value of Original Data]) × Proportion
Where, Proportion = ([Maximum Proportional Value] - [Minimum Proportional Value]) /
([Maximum Value of Original Data] - [Minimum Value of Original Data])
Take the following graphics as example, when the original data is 20, then the value after
conversion is 15 + (20-0) × (55-15) / (100-0) = 23, so the value displayed in the component will
be 23.
