The DeltaV OPC Alarms and Events Server exposes all of the alarms and events associated with the plant area assigned to the workstation on which the server is licensed (ProfessionalPLUS workstation or Application Station).
Use the DeltaV Explorer to:
Assign, to the workstation, the plant areas that contain the alarms and events that you want to expose. (For example, to expose every alarm in every plant area, assign every plant area to the workstation on which the DeltaV OPC Alarms and Events Server resides. Or, to expose only alarms and events in Plant Area 1, assign only Plant Area 1 to the workstation on which the DeltaV OPC Alarms and Events Server resides, and so on.)
Download the changes to the workstation.
Refer to the DeltaV Explorer online help for complete instructions on assigning plant areas and downloading changes to the workstation. Note that it is not necessary to click the Enabled check box on the Alarms and Events Properties dialog to make the alarms and events available to the OPC alarms and events server. This check box is only for the Event Chronicle.
The DeltaV OPC Alarms and Events Server is fully compliant with the OPC Alarms and Events Specification version 1.02.
The OPCAreaBrowser object is an optional object in the OPC Alarms and Events Specification version 1.02. This object provides a way for clients to browse the process areas implemented by the server and to filter event subscriptions by process areas.
The DeltaV install automatically installs the server software, DVOPCAE.exe, to the DeltaV\bin directory. The DeltaV OPC Alarms and Events server (DVOPCAE.exe) is launched when a client application connects to it.
