When the {REMOTE I/O} softkey is pressed (only available on systems
with remote I/O) on the Main Diagnostics Menu screen, the Remote I/O
monitor screen appears. This first screen displays only single transfer
remote I/O words. “REMOTE I/O” appears at the top to identify the
screen, along with the “SETUP MODE” message indicating that the
control is in setup diagnostics mode.
Figure 15A.13 shows an example of the Remote I/O screen.

The screen displays the eight input and eight output ports available.
Following each port number are numbers 15 to 00 which correspond to the
bit numbers for each I/O point on the port. If an input or output bit number
is “ON”, it appears in inverse video. This is a real time display, response is
limited only by delays in screen updates. The screen only shows the
remote I/O words available on this system based on your rack size and
starting address (as configured in AMP).
Pressing the exit softkey (up arrow) at any time displays the Main
Diagnostics Menu screen.
