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 NT631/NT631C by operation from the System Menu.
This section explains how to display and print out the alarm history record
data recorded in the NT631/NT631C.
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).
If necessary, select the next or previous
screen by pressing [↓] (next screen) or
[↑] (previous screen).
The example screen to the left shows a
display for the sort by occurrence
method (from oldest record).
If required, press Prt. to print the display
history record data.
Press Quit.
The NT631/NT631C returns to the DISPLAY
HISTORY MENU screen.
