The user can set the minimum and maximum of input
setting value to determine the range of input setting
value.
Integral
Digits
Fractional
Digits
Use this option to determine the digit number of integer
and decimal fraction. The digit number is not a real digit
number value. It is only the display format. The digit
number will be a real decimal number only when the
data format is selected as “Floating”.
When Variable Minimum/Maximum Value option is selected, it
indicates that the minimum value is determined by Read Address+1
and the maximum value is determined by Read Address+2.
Gain(a)
Offset(b)
Round off
The user can use y = (a) x (read address value) + (b)
this equation to determine the display numeric value (y).
For example, if Gain value (a) is 2 and Offset value (b) is
3, when the read address value is 3, then the display
numeric value will be equal to (2) x 3 + (3) = 9.
If Gain and Offset value is a decimal, please set the data
format as “Floating”.
If Round off option is selected, after the operation of the
equation above, all numeric values can be rounded off
and display on the screen.
Setting
When the user have input the minimum and maximum value, after
pressing OK button, HMI will examine the value by referring to the
selected data length, data format, integral and fractional digits.
