How to redirect a offline alarm to a certain alarm control object in Vista?

Issue

Is it possible to redirect all offline alarms to a certain alarm control object in Vista?

Environment

Vista 5.1.7

Cause

Using the "Configure alarm" function in the Vista server all offline alarms can be sent to a special alarm control object in Vista.

Resolution

Start with creating a new Change of state object in Vista

To create a Change of State

  1. Right-click the Vista server node/object
  2. Point to New, point to Object, and then click "Change of State - System".
  3. Type the name. In the example, "Offline_Alarms".
  4. Right-click the newly created Change of State object. In the example, Offline_Alarms.
  5. Click Properties.
  6. Type a descriptive text. In the example, "Handles alarms for devices going offline".
  7. Change the priority. In the example, change the priority to 1.
  8. On the Alarm tab, in the Alarm processing control box, type the name of the alarm control object for priority 1 alarms. In the example, Alr_Cntrl1.
  9. Click OK.

Filtering and Linking an Alarm

We can now filter out system alarms ($EE_Mess messages) tripped by devices going offline. The alarm texts contain the word "Offline" and we use this as the filter.

To filter and link an alarm

  1. On the Windows task bar, click TAC Vista Server.
  2. On the File menu, click Log in and log in.
  3. On the Configure menu, click Configure Alarms.
  4. Click Add.
  5. In the Text match box, type the filter mask. In the example, "*Offline*".
  6. In the Event object box, click Browse.
  7. In the Units list, browse to the Change of State – System object.
  8. In the Objects list, click the Change of State – System object. In the example, Offline_Alarms.
  9. Click OK.
  10. Minimize Vista Server. When a Xenta device goes offline, a priority 1 alarm appears. The alarm is handled by the Alr_Cntrl1 object
