6-11-5 Displaying and Printing the Alarm History Record

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).

Reference: S With the NT31/NT31C, the record data can also be displayed by registering an alarm history display element on the screen.

SFor details on the alarm history record function, refer to 2-15-2 Alarm History Record Function in the Reference Manual.

SThe 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).

SThe printing method and other information must be set in advance with the Printer Controller (page 172) and Print Method (page 174) memory switches.
