Omron NT631C manual System Configuration, Alarm List/History, Alarm History, Recipe

System Configuration Section 1-3

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 sta-
	tuses.
	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
	(character string) set for the bit memory table.
	The NT631/NT631C 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
