Define an alarm for an embedded block

  1. View the diagram for the module that contains the embedded composite block to which you want to assign an alarm.
  2. Show an Internal parameter block on the diagram by selecting or , and then dragging and dropping it onto the diagram. The Properties dialog is displayed.
  3. In the parameter Name field, type the name of the parameter.
  4. In the Parameter Type field, select the Internal parameter type, and then define the properties. Click OK.
  5. If the Alarm View is not currently displayed, on the View tab, in the Windows group, click Alarm View. A listing of the current alarms for the module is displayed. Select an alarm or simply select the Alarm View pane by clicking anywhere in it.
  6. Right-click, and then click Add to define an alarm.
  7. Select the type of alarm. (If you have not previously defined the alarm types for the system, you may need to define them before they appear in the Alarm type list.)
  8. Click the Browse button to select the internal parameter that you defined.
  9. Set the Priority and, if possible, the Limit.
  10. If you want to perform more advanced functions, click the Advanced tab. Indicate if the alarm is enabled or inverted. (If the alarm is inverted, it will activate when the condition is not True.)
  11. Enter the parameter values that you want to appear in the alarm message. (These are the parameter with which the alarm is associated, and the parameter value that is the alarm limit.).
  12. Click OK.
    Note

    You can define you own custom alarm types for the system using the DeltaV Explorer application. Also, some function blocks come with alarm capabilities, so there are alarms at the module level and at the function-block level.
