The device number of the selected High Density I/O device appears under
the “HIGH DENSITY I/O” heading. This will be a decimal number from
00 to 63.
This screen displays the inputs and outputs that correspond to the pin
numbers listed for the various connectors on the High Density I/O module.
These are IN CN1 (01 through 37), IN CN2 (01 through 37) and OUT
CN3 (01 through 37).
If an input or output is “ON”, its pin number appears in inverse video.
This is a real time display, and its response is limited only by delays in
screen updates. The following abbreviated symbols may appear:
NC = no connection
PW = power connection
If more than one High Density I/O device is on the I/O Ring, a diagnostics
screen for each of these devices can be displayed. To display a diagnostics
screen for the next high density I/O on the ring, press and hold the
[SHIFT] key and press the [DOWN-ARROW] key.
Pressing the exit softkey (up arrow) at any time displays the Ring I/O
Menu screen.
