This section describes how to define the general settings for a numeric entry. The following is an example of the General page of the Numeric Entry property sheet.

The following table describes each property in the General page.

Property

Description

The object’s identifier. It is generated when the object is created. The identifier is unique within the screen where the object is located. The format of the IDs for the numeric entries is NEnnnn.

Note

You can type a note for the object.

Transparent Background

Select this option if you want the object to have a transparent background.

Shape settings

For details about the following properties, see Section 4.3.4 Setting up the Shape of an Object.

, Border Color, BG Color.

External Label

Check this option if you want the object to have an external label. Set up the external label in the External Label page.

Data Type

The data type of the destination variable and the monitored variable. The supported data types include: 16-Bit Unsigned Integer, 32-Bit Unsigned Integer, 16-Bit Signed Integer, 32-Bit Signed Integer, 16-Bit BCD, 32-Bit BCD, 32-Bit Floating Point, 16-Bit Signed BCD (LMB), 32-Bit Signed BCD (LMB), 16-Bit Signed BCD (LMD), 32-Bit Signed BCD (LMD), 8-Bit Unsigned Integer and 8-bit Signed Integer.

Display Type

The display type of the value of the monitored variable. The following table shows the available display types for each data type.

Data Type

Available Display Types

16-Bit Unsigned Integer

16-Bit Unsigned Decimal, 16-Bit Hexadecimal, 16-Bit Octal,16-Bit Binary

32-Bit Unsigned Integer

Note:

LMB: Stands for "Left Most Bit". If the left most bit of a value is "1", the value represents a negative value.

LMD: Stands for "Left Most Digit". If the left most byte of a value is "F", the value represents a negative value.

Separator

Check this option if you want the binary number to display with dot separator positioned in every four numbers. Available only when the display type is 8-Bit Binary,16-Bit Binary and 32-Bit Binary. eg.: 1111.1011.1000.0101

Write Address

Specifies the destination variable where the entered value will be written.
Click

to enter an address for this field. Click

to select a tag for this field.

Monitor Address identical to Write Address

Specifies that the monitored variable is the same as the destination variable. With this item checked, you don’t need to specify the monitored variable in the Monitor Address field.

Monitor Address

Specifies the monitored variable.
Click

to enter an address for this field. Click

to select a tag for this field.

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 text. 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 displayed.
When the Display Type is not 32-bit Floating Point, this property specifies not only the number of fractional digits displayed, but also the number of least significant digits 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

Example 2:

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	123.45
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.

Alignment

The alignment of the displayed value. There are three types of alignment: Left, Center, and Right.

Justification

The justification of the displayed value. There are three types of justification:

Option

Description

Zero Suppress

The leading digits will not be displayed when they are 0.

Leading Zeros

All digits will be displayed.

Leading Spaces

The leading digits will be displayed as a blank character when they are 0.

Data Entry

Specifies how to enter a value for the numeric entry at runtime. There are two options:

Option

Description

Pop-up Keypad

You can bring up the keypad by pressing numeric entry and then enter a value with the keypad.

On-screen Keypad and/or Function Keys

You can move the cursor by using the function buttons with the operation of “Select Next Data Entry Object” or “Select Previous Data Entry Object” to select numeric entry. If there is an on-screen keypad, you can enter a value for the numeric entry immediately. You can also use the function buttons with the operation of “Increase Value By One” or “Decrease Value By One” to change the value of the destination variable.

Note: When On-screen Keypad and/or Function Keys option is selected, you can only enter a value for the numeric entry with the input focus. To set the input focus on the corresponding object, you need to click the object first.

Macro

Use

Check this option if you want the numeric entry to have a macro. Specify and edit the macro in the Macro page.

When to Run
