Use function task panes to define PI DataLink functions.

A task pane is a panel of controls that you can move and dock. You can continue to work on a worksheet while a task pane is open.
To open a function task pane:
-
Select the desired output cell, and then select a function command on the PI DataLink tab to add a function.
-
Select a cell in an existing function array to open the corresponding task pane and edit the function inputs.
Note: You can turn off automatic display of task panes if you prefer. See Manage PI DataLink settings from Excel.
-
Right-click a function-array cell, and then select the function name to manually open the task pane.
In an open function task pane:
-
Enter or change input values, and then:
-
Select OK to save the input values, write the resulting function array, and close the task pane.
-
Select Apply to save the input values and write the resulting function array without closing the task pane.
-
-
Select the arrow button to select the Move, Size, or Close commands.
-
Drag the title bar to undock the task pane.
-
Double-click the title bar to dock the task pane.
-
Place your cursor at the edge and drag to resize the pane.
