Use the Data Item page to define the data items of the data for a recipe block. The following is an example of the Data Item page.

The Data Item page contains two parts. The left side of the data item list shows the address and name of each data item . The right side shows the properties of the selected data item. You need to make a selection before editing the data item. To select a data item, click the row of the data item in the data item list. To select multiple rows for moving up or down, click the row on its header column and use Ctrl + Click to add a row to the selection. The following table describes each property of the data item.

Property

Description

Address

The address of the latest value of the data item.

Name

Click the cell to specify the name of the data item for the language specified in the Language field.

Move Up

Click the button to move the selected data item(s) before the previous data item. The Move Up button will help you to reorder the display sequence of the data items. It will not be available when the first row is selected.

Move Down

Click the button to move the selected data item(s) after the next data item. The Move Down button will help you to reorder the display sequence of the data items. It will not be available when the last row is selected.

Language of Data Item Name

Select a language so you can view and edit the name of the data item for that language.

Data Item

Data Type

The data type of the data item. 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, Byte Array (Character String), and Word Array (Double- Byte Character String).

Display Type

The display type for the value of the data item. 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
32-Bit Unsigned Integer	32-Bit Unsigned Decimal, 32-Bit Hexadecimal, 32-Bit Octal
16-Bit Signed Integer	16-Bit Signed Decimal
32-Bit Signed Integer	32-Bit Signed Decimal
16-Bit BCD	16-Bit Unsigned Decimal
32-Bit BCD	32-Bit Unsigned Decimal
32-Bit Floating Point	32-Bit Floating Point, Exponential Format
Byte Array (Character String)	ASCII String, Western European String, Cyrillic String
Word Array (Double- Byte Character String).	Chinese (PRC) String, Chinese (Taiwan) String, Unicode String

Total Digits

Specifies the number of digits to be displayed for the value of the data item.

Fractional Digits

Specifies how to display the fractional part for the value of the data item. 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 as a fixed point number.
Example:

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

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

Scaling

Check this option if you want the value of the data item to be displayed in a scaled manner. The following is the scaling formula:
DisplayedValue = SampledValue * Gain + Offset
Note: The Gain and Offset are 32-bit floating point numbers. They have, at most, 6 significant digits. Rounding and truncation errors may happen.

Gain

Available when the Scaling option is checked. Specifies the Gain used in the scaling formula.

Offset

Available when the Scaling option is checked. Specifies the Offset used in the scaling formula.

Range Check

Check this option if you want the data item to verify the entered value according to the specified minimum and maximum. If the entered value is not within the allowable range, the entered value will not be output.

Min

Specifies the minimum value.

Max

Specifies the maximum value.
