A Math worksheet is used to implement program logic (using the Built-in Scripting Language) that should be continuously executed during runtime, rather than on specific actions like the user pressing a button on a screen.
- On the Insert tab of the ribbon, in the Task Worksheets group, click Math;
- Right-click the Math folder in the Project Explorer, and then click Insert on the shortcut menu; or
- Click New on the Application menu, click the File tab, and then select Math Worksheet.
To edit an existing Math worksheet, double-click it in the Project Explorer.
- Header area (top section), which contains information for the whole group; and
- Body area (bottom section), where you define each tag, expression, and Programming Lines (logical routines and mathematical calculations through functions and logical operations) in the group.
- Description field: Type a description of the worksheet for documentation purposes.
- Execution field: Type an expression, a single tag, or a constant value to determine when the worksheet should execute.
Note: The project executes the worksheet only when the Execution field result is not zero. If you always want the worksheet to execute, type a 1 (constant value) in the Execution field.
- Tag Name field: Type a tag to receive a return value from the specified calculation in the Expression column.
- Expression field: Type an expression to return a return value to the specified tag in the Tag Name column.
To execute a Math worksheet at a specific time, separate from whatever is configured in the Execution field, use the Math function anywhere an expression is allowed.
