2.7 Alarm
Management
Alarms and events originate from a number of sources: Data received on a serial port, Timer
events, Real-world measurements, as well as other activities internal to the ASG Guard/ASG
Guard Plus.
When the ASG Guard/ASG Guard Plus processes an alarm or event, it checks the Action Table
to determine if it is listed. If the alarm matches one listed in the Action Table, the event is placed
in the Event Table for processing and listed in the system log for reference. To process the event,
the ASG Guard/ASG Guard Plus performs the associated Action Routine, which performs a task
associated with the alarm.
Usually the event is processed right away, and the appropriate action is taken (for example,
delivering the alarm through a dial-up connection). If the event can not be acted upon
immediately, it remains in the Event Table until the required time has elapsed, or the necessary
resources become available (for example, the modem becomes free).
Action Routines are scripted functions that can perform a wide range of tasks associated with
particular or general alarms. Certain Action Routines are included with the system, while others
can be created and loaded into the ASG Guard/ASG Guard Plus in order to customize the alarm
processing mechanisms and interface. Action Routines can be used to deliver alarms, take action
on a host port, provide extra alarm filtering, or collect information on which subsequent alarms will
be based. Action Routines can also create new alarms (called Pseudo Alarms) which allows the
process to feed back on it.
