Section 4-13
4-13 Creating Alarm Lists/Histories
This section describes how to create “alarm lists” − which automatically display a
character-string memory table in accordance with the status of the allocated bit in
a bit memory table
− and “alarm histories”, which record and display the status of
allocated bits.
The alarm list/history function is only available when using an NT30, NT30C,
NT612G, or NT610C and Ver.3 or a later version of the direct connection function.
S
Alarm list: The contents (messages) of character-string memory tables,
or images/library data, that correspond to the allocated bit in a
bit memory table are displayed.
If a screen number is set in advance, screen switching is also
possible.
S
Alarm history: The day and hour on which the allocated bits in a bit table are
set to “1” (come ON) is recorded and the order of occurrence
or order of frequencies is displayed. It is also possible to dis-
play corresponding images or library data.
