Addressing and Interrupts
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 I/O address is the sum of the base address and the offset address.
The registers and their meanings and the offset addresses are described below.
