Alarm List, Alarm History
Reference: The number of characters in the specified date/time display are added to the
max. message length (1 to 40 characters) set in the general properties. For ex-
ample, if the max. message length is set to 40 characters and the Info Type is set
to Y/M/D h:m (15 digits), a total of 55 characters will be displayed in the alarm
history.
Display Result
The history is displayed as follows depending on the settings made for General
and Settings.
For details on the method of display according to the General settings, refer to
Common Attributes (page 177).
Alarm histories allow the screen to be switched in accordance with bit memory
table settings. For details, refer to 2-3-3 Bit Memory Tables (page 75).
Timing of Message Reading
For alarm lists and alarm histories in frequency order, when a message is dis-
played, scrolling, or screen switching, the character string memory table set for
the bit memory table is read, and the latest message is displayed.
In contrast, in the case of alarm histories in occurrence order, only when the sta-
tus of the allocated bit of the bit memory table changes to 1 (ON), the character
string memory table set for the bit memory table is read and its contents are re-
corded. Accordingly, even if the contents of the character string memory table
change later, the displayed message will be kept the recorded contents. Howev-
er, if the status of another monitored host bit changes to 1 (ON) while an alarm
history in occurrence order is being displayed, the latest message at that point is
displayed.
Display at Message Update
When the status of a monitored host bit changes during display of an alarm list/
alarm history, the display changes as follows.
With an Alarm List
With an alarm list, when the status of a monitored host bit changes to 1 (ON), the
corresponding message is displayed, and when it changes back to 0 (OFF), the
message is cleared (the messages are displayed in ascending order of bit
memory table numbers).
