FactoryTalk Historian DataLink User Guide
18
 Select an item from choices in a list , such as a calculation or a
sampling method.
 Reference spreadsheet cells that contain arguments, such as a
tag name, output cell location, or time stamp.
Be sure to type strings in cells that you may reference with a leading
apostrophe ('). This forces Excel to interpret the contents as a string.
 Select values from a FactoryTalk Historian server or other sources
through a tag or module database search.
For example, you can type a tag name string into the Tagname field, or
click the button next to the field to display the Tag Search dialog box, and
search the FactoryTalk Historian server for tags.
You can also manually supply a reference to a spreadsheet cell that
contains a tag name:
 Click first in the edit field, and then click the cell (or click the cell and
drag to an adjacent cell to select a range) on the spreadsheet.
DataLink automatically enters the cell reference into the edit field.
Some entry fields display a default entry when the dialog box or pane opens.
Fields marked Optional are optional, and a value is not required.
Standard Arguments
Some arguments are common to most FactoryTalk Historian DataLink
functions in dialog boxes or task panes, and are usually required to define
the function:
 Tagname(s) or Expression (page 19)
 Start Time (page 19)
 End Time (page 20)
