This section describes how to use the alarm list and the alarm history which
monitor the status of bits in the host and, if a bit status changes to 1 (ON), display
the corresponding message and the image/library data.
The alarm list/history can be checked using the System Menu of the PT. It is also
possible to check them during operation by registering them to the screen as an
element (alarm list can only be used as an element.).
The Support Tool can read out the alarm history record data stored to the PT to
the host as a text file. For the procedure for reading the alarm history record data,
refer to the NT-series Support Tool Ver. 4.1 for Windows Operation Manual .
An alarm list can only be displayed as an element while an alarm history can be
displayed on a confirmation screen which is called from the System Menu as
well as displayed as an element.
The status of the bit to be monitored (alarm list) and the record of bit status transi-
tion (alarm history) can be confirmed while the PT is operating.
