Monitoring Variables with the Watch List View

The Watch List view displays information about a single variable or multiple variables contained within a system or process. The Watch List view displays the variable location, current value, data type, timestamp, access (read/write) status, and quality. The quality indicates errors or other conditions that apply to the variable.

Note Variables that use the array and cluster data type do not display the values of individual components.

1. Right-click a system tree object, which includes all systems, processes, and variables available in the system tree.
2. Select Watch List from the shortcut menu to open a new Watch List view.
3. To customize the Watch List view, right-click anywhere inside the Watch List view.
4. Select Show Columns from the shortcut menu to show and hide any of the information columns available in the Watch List view. You also can reorder the columns by dragging the column headings.
