In this example, a large plant has two main areas (AreaA and AreaB), each of which has a set of skilled personnel that operates and monitors only the equipment processes in that area. Because the plant operators are specialized only in their own area and need only respond to the alarms in their area, the plant management has requested that the workstations in each area display only those alarms that are relevant.
In this scenario, we have the following workstations:
• WorkstationAreaA
• WorkstationAreaB
WorkstationAreaA Configuration
The workstation named WorkstationAreaA requires the following configuration:
1. A text file named, WorkstationAreaA.ini must be present in the workstation's application directory.
2. The [Alarm_Manager] section added to the WorkstationAreaA.ini file.
3. The AlarmArea variable should be set to AreaA to indicate that only alarms configured with an Area property of AreaA should be visible on this workstation.
The completed WorkstationAreaA.ini file should appear as follows:
[Alarm_Manager]
; The alarm areas to show
AlarmArea = AreaA
The result of the above configuration is that the workstation named WorkstationAreaA will only display alarms whose Area property has been configured as "AreaA".
WorkstationAreaB Configuration
The workstation named WorkstationAreaB requires the following configuration:
1. A text file named, WorkstationAreaB.ini must be present in the workstation's application directory.
2. The [Alarm_Manager] section must added to the WorkstationAreaA.ini file.
3. The AlarmArea variable should be set to AreaB to indicate that only alarms configured with an Area property of AreaB should be visible on this workstation.
The completed WorkstationAreaB.ini file should appear as follows:
[Alarm_Manager]
; The alarm areas to show
AlarmArea = AreaB
The result of the above configuration is that the workstation named WorkstationAreaB will only display alarms whose Area property has been configured as "AreaB".
Note: Alarm area filtering does not prevent tags from loading; therefore, the alarm tags associated with the hidden alarm areas will continue to appear in the Tag Browser (for those users who have the appropriate security privileges to access the Tag Browser).
