The Alarm/Event Function monitors the status of a bit in the host and displays
a message or warning to the user when that bit goes ON. This function can be
used to record events such as errors or the start of operation.
The main feature of the Alarm/Event Summary Function (current alarm dis-
play) is its ability to receive alarm/event notifications and track related informa-
tion, such as the message set for the alarm/event, the time that the alarm/
event occurred, and the time that the alarm/event was cleared.
The Alarm/Event History Function (alarm history display) lists past or present
alarms/events as well as the message set for the alarm/event, the time that
the alarm/event occurred, and the time that the alarm/event was cleared.
In addition to checking the Alarm/Event History from the NSJ Controller's Sys-
tem Menu, both the Alarm/Event History and Summary can be checked dur-
ing operation from an object set in the screen. Also, the Alarm/Event History
recorded in the NSJ Controller can be converted to a CSV file and saved in
the Memory Card by turning ON System Memory bit $SB33.
NSJ Troubleshooter Screens can be registered in this Alarm/Event History
Function, so the Alarm/Event History Function can also manage errors that
occur in the Controller Section or built-in DeviceNet Unit.
