Set up class-based events

You can bind class properties to event variables so that an event can detect a property change in any equipment to which that class has been added.

About this task

Note: This does not allow you to detect property changes in equipment properties where that class has been used as the Type.

Procedure

  1. In the navigator, click Events.
  2. In the Folders list, select the resource type you want to work with.
    Tip: As more lists appear, select the appropriate resource until you find the one you want to work with.
  3. In the Displays panel, select an editor.
    The editor appears in the workspace, displaying the resource information.
  4. On the Trigger Settings tab, select either:
    • Trigger only on Variable Value changes
    • Trigger on Event or Variable Value changes
  5. Click the Variables tab, and then click Add.
  6. Configure the variable as follows:
    1. In the Variable Name field, enter a name.
      Note: The variable name must be alphanumeric and must not contain spaces.
    2. Select Bind variable to external data, and then click Configure Data Item.
      The Configure Variable Data Source dialog box appears.
    3. Select an equipment class, and then click Next.
      Note: A class property is editable and can be deleted even when it is being monitored by an enabled condition event; however, the event is invalid if the class property is changed or deleted from the equipment class.
    4. In the Item specific configuration section, click the ellipsis button. The Data Source Browser appears.
    5. Select an equipment class property, and then click OK.
    6. Click Finish, and then click Save.
