Is it possible to redirect all offline alarms to a certain alarm control object in Vista?
Using the "Configure alarm" function in the Vista server all offline alarms can be sent to a special alarm control object in Vista.
Start with creating a new Change of state object in Vista
To create a Change of State
- Right-click the Vista server node/object
- Point to New, point to Object, and then click "Change of State - System".
- Type the name. In the example, "Offline_Alarms".
- Right-click the newly created Change of State object. In the example, Offline_Alarms.
- Click Properties.
- Type a descriptive text. In the example, "Handles alarms for devices going offline".
- Change the priority. In the example, change the priority to 1.
- 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.
- 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
- On the Windows task bar, click TAC Vista Server.
- On the File menu, click Log in and log in.
On the Configure menu, click Configure Alarms.
- Click Add.
- In the Text match box, type the filter mask. In the example, "*Offline*".
- In the Event object box, click Browse.
- In the Units list, browse to the Change of State – System object.
In the Objects list, click the Change of State – System object. In the example, Offline_Alarms.
- Click OK.
- Minimize Vista Server. When a Xenta device goes offline, a priority 1 alarm appears. The alarm is handled by the Alr_Cntrl1 object
