Additional information for system coupler cards
If a large bus configuration (system coupler card and
number of devices > 225, all with 32 bits of DIO) is
read with the "Create_Configuration" service
(0710 hex ), the default I/O data will be stored in
address area 0000 hex to 03FF hex . This causes a
conflict with system coupler address 0380 hex .
Remedy: Assign the system coupler to an address
located after the address area of the default I/O data.
