Omron NT31 NT31C manual Alarm List/History, Alarm History, Recipe

	Section
Alarm List/History	The alarm list/history function displays messages in list form, or graphics
	(image/library data), in accordance with changes in bit memory table statuses.
	For the alarm list, a series of bit memory tables are monitored, and messages
	(contents of character string memory tables) set for bit memory tables that come
	ON are displayed.
	For the alarm history, bit memory tables for which the history property is set are
	continually monitored, and the time when they come ON and number of times
	they come ON are recorded and displayed together with the message (charac-
	ter string) set for the bit memory table.
	The NT31/NT31C allows selection of the display order as the newest record first
	or the oldest record first by memory switch setting.
	The alarm list function is used to determine which bits are ON at the present
	time. The alarm history function is used to determine the times at which alarms
	occurred in the past and how many times alarms have occurred.
