5A-25
The remote I/O circuitry and connector are integral parts of the wiring
board in the 9/440 resolver--based system module. Figure 5A.11 shows the
remote I/O connector mounted on the 9/440 resolver--based control wiring
board.
Wire connections for the remote I/O communications are made through the
TB4 NODE ADAPT connector. Connect the wires for remote I/O as
shown in the following figure. Refer to your 1771 I/O documentation for
details on making remote I/O connections.

Assuming you have:
made all necessary remote I/O communication connections on your
1771 I/O network
configured your remote I/O port for the remote I/O network in AMP
written PAL to set $RMON true during the first PAL foreground
execution, and to handle input and output words ($RMI1 -- $RMI8
inputs to PAL and $RMO1 -- $RMO8 outputs from PAL.)
