To view alarms and record events from the remote zone in the local zone, assign Remote Zone Areas to the Alarms and Events subsystem of workstations in the local system. Doing so:
Adds the alarms from the Remote Zone Area to the alarm scope of the workstation (defines what alarms are eligible to show in active/suppressed alarm lists, alarm banner, and so on).
Includes all events from the Remote Zone Area in the Event Chronicle (should one be enabled) on that workstation.
The DeltaV OPC Alarms and Events Server does not support Inter-Zone alarms and events. Alarms and events from remote zones appear in the Event Chronicle of a workstation (if the remote zone area is assigned to the workstation's Alarms and Events subsystem), but are not seen by OPC Alarms and Events clients (Plant Event Historian, for example) connected to the workstation.
The alarms and events that are recorded in a workstation's Event Chronicle (if it is enabled) depend on the following:
The workstation's alarm scope — The local plant areas and Remote Zone Areas assigned to the workstation's Alarm and Events subsystem.
The shared areas in the remote zone — Areas in the remote zone must be shared for alarms and events from the remote area to appear in the local zone's Event Chronicle.
The alarms that appear in a workstation's alarm banner and alarm displays depend on the following:
The areas shared in the remote zone — Areas in remote zones must be shared with the local zone for alarms to appear. Alarms from remote zone areas that are shared as read only cannot be acknowledged from the local zone.
The workstation's alarm scope — The local plant areas and Remote Zone Areas assigned to the workstation's Alarm and Events subsystem.
The alarm scope of the currently logged in user — The local plant areas and Remote Zone areas for which the currently logged in user has been granted any security key from the DeltaV User Manager.
Only those alarms and events that meet these criteria appear in the alarm banner and alarm displays.
