The alarm history record function is a function that continually monitors, during
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 number 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).
S With the NT31/NT31C, the record data can also be displayed by registering an
alarm history display element on the screen.
S For details on the alarm history record function, refer to 2-15-2 Alarm History
Record Function in the Reference Manual.
S 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 179).
S The printing method and other information must be set in advance with the
Printer Controller (page 172) and Print Method (page 174) memory switches.
If required, press Prt. to print the display his-
tory record data.
