Addressing
The IF 961-CT1 interface submodule is addressed with the M7-300/400-reserved
I/O address area (starting from C000
H
).
Addressing in the M7-300/400-Reserved I/O Address Area
The base address depends on the interface submodule slot in the expansion
module or the programmable module. See the descriptions “M7-300 Expansions”,
“M7-400 Expansions” or the description of the M7-400 programmable modules for
the slot-dependent base address of the interface submodule.

The interface submodule supplies an interrupt request (IRQa).
You can define the assignment of the IRQa interrupt request to the relevant
processor interrupt request in the BIOS setup.
