Background Tasks
• Transaction Completed field: Type a tag that changes value when the transaction is executed.
• Select, Next, Insert, Delete, or Update Trigger fields: Type a tag to work as a trigger, where each value change
causes the system to execute the corresponding command. At least one trigger field is required.
Use the Body parameters on this worksheet as follows:
• Tag Name field: Type the names of tags to update with file contents or tags whose values should be written to
a file.
• Column: Type the location in which to find data in the file (for example, R3CH corresponds to Row 3, Column

You must use the Windows Control Panel to set up the ODBC interface for Excel files. The procedure is as
follows:
1. Click the Start > Settings > Control Panel.
2. When the Control Panel window displays, double-click on the ODBC icon to open the ODBC Data Source
Administrator dialog.
3. In the ODBC Data Source Administrator dialog, click Excel Files in the User Data Sources list, and then
click the Configure button.
4. When the ODBC Microsoft Excel Setup dialog displays, type the Windows configuration name to be used in
the DSN field on ODBC worksheet into the Data Source Name field.
5. Click the Select Workbook button to configure the Excel file you want to use.
6. Return to the ODBC Data Source Administrator dialog and verify that your User DSN displays in the list.
Click OK to close the dialog.
7. After configuring the ODBC Windows interface, you must configure the project's ODBC worksheets.
8. From the Tasks tab, insert a new ODBC worksheet.
9. Be sure you set the ODBC Runtime to start automatically using the Execution Tasks dialog (Tasks on the
Home tab of the ribbon).
To start this configuration, you simply need to run the project. Your project will handle the Select, Next, Insert,
Delete, and Update triggers to allow data to exchange throughout rows in Excel and tags configured in the
worksheet.
