9.5.1 DATA DISPLAY
The Alarm History view shows the date and time of the events, pen No. and its tag name, and the alarm message
(comment) pre-described for the particular status.
Sixteen (16) events are listed on the view, and the maximum of 1000 events can be searched and displayed with
the 512 MB and 1GB CF card. The capacity depends upon the CF card capacity (See Section “10. DATA & FILES”).
To the right top of the screen, the position of the presently selected alarm event among the total number of events is
indicated.
Blinking message line means that the event is not acknowledged yet. Touch it twice to acknowledge (once to move
the cursor to the line, twice to acknowledge), and it stops blinking. In order to acknowledge all events on the screen,
use ACK All button.
While Auto Update is enabled, other control buttons are unavailable.
Input pens are identified as Ixx (xx = pen number), and Function pens are identified as Fxx (xx = function pen number).
9.5.2 DATA SEARCH BY ALARM EVENT
Touching Jump key when a specific alarm event is selected switches the screen to the Retrieve view where the data
at the moment of alarm event is indicated.
Alarm events are stored according to the sampling rate (100 msec. or 500 msec.), while pen data are recorded ac-
cording to the storing rate. When the storing rate is 1 second or longer, the time index of an alarm event does not
match the storing rate. However, the 73VR21x searches data at the time index by the storing rate. For example, with
1-minute storing rate, searching the event at 16:03:40 means searching data at 16:04:00.
