The alarm history record function is a function that continually monitors, dur-
ing operation, the status of bits at the host designated in advance with a bit
memory table, and records the time when these bits come ON, and the num-
ber of times they come ON.
The record data can be displayed, and printed out at a printer connected to
the NT31/NT31C by operation from the System Menu.
This section explains how to display and print out the alarm history record
data recorded in the NT31/NT31C.
Note that there are two display methods sort by occurrence (ON time order)
and sort by frequency (order of number of times the bits have come ON).
• With the NT31/NT31C, the record data can also be displayed by register-
ing an alarm history display element on the screen.
• For details on the alarm history record function, refer to 2-15-2 Alarm His-
tory Record Function in the Reference Manual.
• The order of display for sort by occurrence display (from oldest record or
from newest record) is set with the Hist. Disp. Method memory switch
(page 180).
• The printing method and other information must be set in advance with
the Printer Controller (page 173) and Print Method (page 175) memory
switches.
If required, press Prt. to print the display
history record data.
Press Quit.
The NT31/NT31C returns to the
DISPLAY HISTORY MENU screen.
