Temperature sensors or pressure sensors also display the
current sensor state, (i.e., whether there is a fault condition or
the sensor is in a normal monitoring state). The user can toggle
between displaying the control digital and analog I/O (the initial
display is the digital I/O). The Digital or Analog button on the
bottom of the diagnostic page changes the I/O displayed to the
type indicated by the button.
The following data is displayed on the control diagnostics page
(see Fig. 91–93).
“On” status is indicated by a green LED and “Off” status is
indicated by a red LED.
Analog I/O data is displayed as bar charts depicting the I/O
level (see Fig. 94). Analog I/O that is not enabled for the
installation displays a blank I/O level. To see all analog I/O, use
the horizontal scroll bar to move the view left and right.
