RS.8D.M1.22 AK2-SC 255 Reference Manual 189
Displaying History Just above the icon menu bar at the bottom of the screen are three “buttons”: View,
Auto View, and Clear. Their functions are as follows:
View Displays history for the datapoints shown at the top of the screen.
Auto View Displays history for the first five points in the body of the current
screen regardless of the points selected in the upper portion of the
screen. The points selected in the top of the screen remain unaf-
fected. (Also see the paragraph on Auto View following the next
illustration.)
Clear Clears the column labeled view in all the Configure History Display
screens (for all the points represented by the icons on the menu at the
bottom of the screen). No history is lost by using the Clear button.
Only the setup for display is cleared. The point names at the top of
the screen will change to “Not configured.”
