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

The Data Item page contains two parts. The left part is the data item list that shows the address and name of each data item in rows. The right part shows the properties of the selected data item. To select a data item, click the row of that data item in the data item list.

The following table describes each property of the data item.

			Data Type			Available Display Types
Property			Description
Address			You can use the address shown here to refer to the latest sampled value of the data item.
Name			Specifies the name of the data item for the language specified in the Language Of Data Item Name field.
Language of Data Item			Select a language so you can view and edit the name of the data item on the left part 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.
			16-Bit Unsigned Integer			16-Bit Unsigned Decimal, 16-Bit Hexadecimal, 16-Bit Octal, Indexed String, Identified String
			32-Bit Unsigned Integer			32-Bit Unsigned Decimal, 32-Bit Hexadecimal, 32-Bit Octal, Indexed String, Identified String
			16-Bit Signed Integer			16-Bit Signed Decimal, Indexed String, Identified String
			32-Bit Signed Integer			32-Bit Signed Decimal, Indexed String, Identified String
			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,
			Note: For details about the Indexed String and Identified String, please see Section 13.1.6. Difference between Indexed String and Identified String.
	Total Digits / Length		Specifies the number of digits to be displayed for the value of the data item.
	Fractional Digits		Specifies how to display the fractional part of 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		123.45	123.45
			16-bit Signed Decimal	5	2		-5	-0.05
	Text Table		Available when the display type is Indexed String and Identified String. Select a text table where the string is located.
	First String No.		Available when the display type is Indexed String and Identified String. Specifies the first string number of the text table.
	Last String No.		Available when the display type is Indexed String and Identified String. Specifies the last string number of the text table.
	Scaling	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 occur.
		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.
Database	Show Column Names		Available when the target panel is HMI runtime. Check this option to show the column name of the table in the database in the top-left part.
Database	Column Names		Select a language so you can use the Data Item Name of that language as the column name.
