Use a Flowchart to Build an Expression

If you want to use an expression that comprises a series of Boolean comparisons, you can use the Flowchart Editor to graphically build that expression:

1. Right-click on the required cell in the Data Set Row.
   A context sensitive menu is displayed.

   

2. Select the Flow Chart option.
   The Expression Flowchart window is displayed.

   

   The Expression Flowchart window allows you to create IIF expressions in a diagram format.

3. Build the required expression using the Flowchart window. (For more information on using the Expression Flowchart window, see Expression Flowchart in the ClearSCADA Guide to Expressions.)

   Example:

   

4. Select the OK button on the Expression Flowchart window.
   The window is closed and the expression is displayed in the Data Set Row cell.
