Alarm List & History Display Functions
Caution
The NT30/30C can monitor the state of PC bits of the host and display the corre-
sponding message (using the character string memory table entry) or image/li-
brary data (alarm list display) when a specific bit becomes 1 (ON).
The NT30/30C can record that those bits become 1 (ON) and also display them
in the order of frequency or occurrence (alarm history display).
Since the alarm list/history data are backed up by the built-in battery, they are not
lost when the power is turned OFF.
Alarm list display has the following functions.
The NT30/30C monitors multiple bits according to the setting of the bit memory
table entry and displays the character string memory table entry (message) set to
the corresponding bit memory table entry when there is any bit that becomes 1
(ON). Since the display column of a message is also a touch switch, correspond-
ing image/library data can be displayed by pressing the message being dis-
played.
If the description of alarms is provided in the character string memory table entry
and the corrective actions against those alarms are described for the image/li-
brary data, it is possible to take appropriate measures rapidly.
S To Display Multiple Messages
If not backed up by the built-in battery, the memory switch settings will all be ini-
tialized to the values set with the NT-series Support Tool when the power is
turned OFF.
If the message “Battery Lowered” is displayed while the NT30/30C is being
used, replace the built-in battery immediately. For details on how to replace the
battery, see Replacing the Battery (page 253).
When multiple bits become 1 (ON), the bit memory table entry with smaller
table entry number is displayed preferentially.
When multiple messages can be displayed, the messages of higher priority
(smaller bit memory table entry number) will be displayed earlier.
The display column of message and the image/library data displayed corre-
spondingly are referred to as Alarm Group collectively. The NT30/30C can dis-
play up to four individual alarm group on one screen and simultaneously show
up to 12 messages in one alarm group.
