PI AlarmView
Summarizes PI Alarm server information and displays those data in a hierarchical tree structure to any number of clients on- or off-site.
Component Summary
When PI Alarm discovers an event outside normal parameters, PI AlarmView lets you know. It is a Windows application that creates a hierarchical information tree, displaying both the overall alarm structure, as well as specific points. AlarmView is a user-friendly way to keep the right people in touch with production operations.
Because the PI System makes its real-time data instantly available, PI AlarmView is a constant source of reliable information. When an alarm is triggered, you can review not just the current event, but historical patterns as well. Even when windows are minimized or hidden, PI AlarmView is on the job. A flashing icon lets you know if your attention is required.
Technical Overview
PI AlarmView is the client application that displays alarm data collected by the PI Alarm subsystem. It gives you a picture of the overall alarm structure, detailed information on specific points, and a tool for acknowledging alarms. Data are presented in a hierarchical tree structure to any number of Windows clients that can take advantage of ActiveX controls, on- or off-site.
- PI AlarmView is constructed as a set of ActiveX controls:
- PI AlarmHierarchy: A tree control displaying the hierarchical alarm structure of your environment
- PI AlarmPoints: A table displaying sets of alarms for a particular unit
- PI AlarmHistory: A table displaying alarm history for specific alarm points
- PI UpdateManager: An update manager control that informs the first two controls of the current status of the alarms monitored
These controls can also be used individually within applications that are ActiveX containers, such as PI ProcessBook, Microsoft Excel, Internet Explorer, and applications built with Microsoft Visual Basic for Applications (VBA).
- AlarmGroups: The Alarm subsystem in PI uses a structure built from AlarmGroups. Groups can also contain subgroups affording a hierarchical structure of alarms. The groups are defined using a set of tags. One tag, the Group ID, establishes its position in the alarm structure. Then, up to seven additional tags indicate which points in the group are in an alarm state and unacknowledged.
- AlarmPoints: An AlarmPoint is a special kind of digital tag. Its value is a digital state that gives information about the alarm status of its source tag. The digital states a point can assume as values are defined as its digital set. (PI DataStorage comes with four digital sets that contain analog and digital alarms.)
The alarm states -- Hihi, High, Low, Lolo -- are associated with the value of the source tag and depend on the nature of the information recorded at the source tag. The alarm priority -- 1 to 3 -- rates the importance of the alarm, indicating how urgently action is required. An alarm acknowledgement confirms that a situation has been recognized.
