Display

Monitor Address

Select this option so the advanced numeric display will monitor the variable specified in the Monitor Address field and display its value. When this option is selected, you need to specify the monitored variable.
Click

to enter an address for this field. Click

to select a tag for this field.

Expression

Select this option so the advanced numeric display will display the result of the arithmetic expression specified in the Expression field. ?When this option is selected, you need to specify the arithmetic expression that calculates the value to be displayed.
Click

to enter an address for this field. Click

to select a tag for this field.

Macro

Select this option so the advanced numeric display will run the macro defined in the Display Macro page before displaying the value of the internal variable $D. The macro can decide the value displayed by saving the desired value in the internal variable $D.

Operator Input

Select this option so the advanced numeric display will allow the operator to enter values for it.

Write Address

Specifies the destination variable where the entered value will be written to when the Operator Input is selected. Click

to enter an address for this field. Click

to select a tag for this field.

Output

Direct

Select this option so the advanced numeric display will write the entered value to the destination variable specified in the Write Address field directly.

Expression

Select this option so the advanced numeric display will write the result of the arithmetic expression specified in the Expression field. When this option is selected, you need to specify the arithmetic expression that calculates the value to be output. To use the entered value as an operand in the expression, specify the internal variable $K for the entered value.
Click

to enter an address for this field. Click

to select a tag for this field.

Macro

Select this option so the advanced numeric display will run the macro defined in the Output Macro page before writing the value of the internal variable $W to the destination variable. The macro can decide the value to be output by saving the desired value in the internal variable $W. To use the entered value in macro commands as a parameter, specify the internal variable $K for the entered value.

Font

The font of the displayed value. You can use the drop-down list to select a font, or click

to bring up the Font Templates dialog box and select a font for the current displayed value. You can change the font templates before selecting a font in that dialog box.

Text Color

The color of the displayed value.

Total Digits

The number of digits to be displayed.
Note: This property applies to the display of the initial value, the allowable minimum, and the allowable maximum on the numeric keypad.

Fractional Digits

When the Display Type is 32-bit Floating Point, this property specifies the number of fractional digits to be displayed.
When the Display Type is not 32-bit Floating Point, this property specifies not only the number of fractional digits to be displayed, but also the number of least significant digits to be displayed as the fractional part. With this feature, an integer can be shown and entered as a fixed point number. When the Fractional Digits is nonzero, say N, the entered value will be converted to an integer according to the following formula before being output.
OutputValue = EnteredValue * (Nth power of 10)
Example 1:

Display Type	Total Digits	Fractional Digits	Justification	Monitored Value	Displayed Value
32-bit Floating Point	4	2	Zero Suppress	12.34	12.34
32-bit Floating Point	4	2	Zero Suppress	123.4	23.40
16-bit Signed Decimal	5	2	Zero Suppress	12345	123.45
16-bit Signed Decimal	5	2	Zero Suppress	-5	-0.05

Example2:

Display Type	Total Digits	Fractional Digits	Entered Value	Output Value
32-bit Floating Point	4	2	12.34	12.34
32-bit Floating Point	4	2	123.4	Error!
16-bit Signed Decimal	5	2	123.45	12345
16-bit Signed Decimal	5	2	-0.05	-5
16-bit Signed Decimal	5	2	3	300

Note: This property applies to the display of the initial value, the allowable minimum, and the allowable maximum on the numeric keypad.
