DIAGNOSTICS
The diagnostic page displays analog and digital I/O status of
the control. The digital I/O data is displayed as LEDs that are
either on (green) or off (red) (see Fig. 91–93). Not all digital I/O
can be displayed at the same time on the page, so a horizontal
scroll bar is used to move the view left and right to show all
digital I/O data.
