Configure limits

Before you add a new limit, you must first add a limit name and a context. For more information, see Configure limit names and Configure context definitions.

To add a limit or view properties for a limit

1. On the Limit tab of the analog tag Properties dialog box, click Add or Properties. The Limit Properties dialog box appears.

   

2. In the Context list, select the description of the context.

3. In the Limit Name list, select the name for the limit.

4. In the Value box, type the value that is used as a specific limit for a tag. In theory, a tag can have an infinite number of limits defined.

5. In the Type list, select the type of limit; that is, whether it is a rising (up) or falling (down) limit.

6. In the Priority box, type the priority for the limit. Priorities can range from 1 to over 2 billion, with 1 being the highest priority.

7. Select the Checked check box to enable automatic limit checking.

8. In the Description box, type the description of the limit.

9. Click OK.
