Shelve alarms at runtime

Use a runtime client to shelve and unshelve alarms. From Application Server, you can use Object Viewer to monitor and control shelved alarm attributes. Shelved alarms can also be monitored and controlled from an embedded Alarm Control and at least one animation to write to the AlarmShelveCmd attribute. For information about using the Alarm Control to shelve alarms, see Shelve and Unshelve Alarms at Run Time in the AVEVA OMI help.

To shelve or unshelve an alarm in Object Viewer

1. In Object Viewer, select the object in the Console Tree (left pane) which contains the alarm you want to shelve. The object attributes display in the Details Pane (right pane).

2. In the Attributes list, find the attribute configured with the alarm you want to shelve.

   For example, "Inlet_001.Discrete_001".

3. In the Attributes list, below the attribute in step 2, find the AlarmShelveCmd attribute.

   For example, "Inlet_001.Discrete.001.AlarmShelveCmd".

4. Double-click the .AlarmShelveCmd attribute. The Modify String Value dialog opens.

   

   1. To shelve an alarm, enter a duration in hours or in decimal fractions if the duration is to be less than one hour. The duration cannot be blank.

   2. Enter a reason between the quotation marks for shelving or unshelving. The reason cannot be blank. Select OK.

   3. To unshelve a shelved alarm, enter a value of "0".

The six read-only alarm shelving attributes will display the current shelving status information.
