Remote I/O Communications 8–12
Publication 2706-6.1
The table below lists the number of separate chassis or devices the
scanner can support and how much I/O it can address.
Note: For any application, the total of all the I/O used by each device
(I/O rack, drive system, or DL40 Plus) connected to the cable gives
the number of full racks of I/O being supported by the scanner or
sub-scanner for that application.
