3-7 Using Alarm/Event Summary History Functions
This section describes how to use alarm/event summary/history functional objects.
Alarms/events monitor host bits and display messages for the user when the bits turn ON.
Alarms/events can be used to record errors, operation start, and other events.
The main features of the alarm/event summary function (current alarm display) are to receive notification
of alarms/events and display messages set to the alarms/events and a list of when the alarm/event oc-
curred and when it was cleared. The alarm/event history function (alarm history display) displays mes-
sages set to past or current alarms/events and a list of when the alarms/events occurred and when they
were cleared.
Alarm/event summary histories can be checked under the PT System Menu (histories only) and sum-
maries and histories can be checked during an operation if an alarm/event summary/history functional
object is placed on the screen.
Alarm/event histories recorded on PTs can be saved to a CSV-format file and saved on Memory Cards
by turning ON system memory bit $SB33.
