Operating the DX LCD Display 4-31
The entries in the Alarm Log are listed chronologically from most
recent to oldest. The data shown for each point in the Alarm Log
is the same as in the Point Data screens, with the addition of the
time of occurrence at the end of the line. The status fields of
return-to-normal entries show the text NOR, instead of being
blank, to make them easier to recognize. Dates on which there
were no occurrences are not shown in the log.
Figure 4-20 also shows the three special entries:
Power Restored,
Power Failure, and New DX Controller
, which has a second line
showing the display configuration number and the N2 Address of
the DX controller.
2. Use the
and keys to page through the Alarm Log screens.
You can page through all 24 screens, although only the first few
screens may contain alarm log data.
3. Press the
esc
key from any screen to return to the Main menu.
Note: The Alarm Log feature records alarms as they occur in the
DX controller that is currently connected to the DX LCD
Display. If the DX LCD Display is configured to monitor
one of several DX controllers (N2 Bus operation) or is used
as a portable device, the Alarm Log will contain alarm
records from more than one controller. In an N2 Bus
operation, alarms are not collected from all DX controllers
simultaneously, but only from the DX controller currently
connected to the DX LCD display. The Alarm Log feature is
primarily intended for use in a DX Display permanently
connected to one DX controller.
