Trend Graphs
Trend graphs display chronological changes in the value in a numeral memory
table, converting the value to a percentage within the range –100% to +100% of
a preset value. The trend graph shifts position with the passage of time.
Past data can also be recorded, and the numeral memory table can be read
(sampled) even while the trend graph is not being displayed.
The user can choose to stop sampling, restart sampling, or display past data, by
pressing touch switches.
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 and NT631/NT631C allow selection of the display order for
the newest record first or 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.
