displayed, and the alarm history record function, which continually monitors bit
statuses at the host and records the time when bits come ON and the number of
times they come ON.
The
Hist. Disp. Method setting determines whether — when these record data
are displayed in sort by occurrence — the records are displayed in a progression
from newest to oldest or from oldest to newest.
• From Old Data:
The records are displayed in sequence from the oldest to newest.
• From New Data:
The records are displayed in sequence from the newest to oldest.
The default (factory) setting is From New Data.
Reference: S Install an optional battery in the NT21 when using the display history record
function or the alarm history record function.
S If
a battery is installed, the contents of the history record will be retained even
when the NT21 is turned OFF , but the data will be lost if the battery fails and the
NT21 is turned OFF.

details on the display history record function and the alarm history record
function, refer to 2-15-1 Display History Record Function and 2-15-2 Alarm
