3.8.3 Alarm History Screen
Fig. 3.8.3.1 The Alarm History Screen
The Alarm History screen, shown in Figure 65, displays alarm number, message, and time the
alarm was signalled. Touching an alarm in the table causes additional information to be displayed
in the Description area below the table. The history starts from when the NC was started or the
last time the Clear button was pressed, whichever is most recent.
It is possible to search the alarm history for a string. The toggle in the upper right corner specifies
whether the Alarm or Message field should be used for the search. The string to search for is
entered below the toggle, and the search commences when the Search button is pressed. “String
not found” is displayed in the warning area if the search produces no matches.
The Save As button pops the dialog shown in Figure 3.8.3.2 on page 101. This dialog is used to
specify a file and directory to which the alarm history data shown will be written. A new alarm
history file can be created by selecting a directory and typing in the Filename field. A file may
also be selected directly, at which point its name will be displayed in the Filename field. The dia-
log behavior is similar to a file browser, discussed in “File Browser” on page 23.
