These registers are used as interfaces between pro-
grams.
They do not have a battery backup.

IW00000 to
IW07FFF,
IW10000 to
IW17FFF
These registers are used for input data.
IW08000 to
IW0FFFF
These registers store the motion monitor parame-
ters.
These registers are used for Motion Modules.
IW20000 to
IW21FFF
These registers are used as interfaces between
CPU Units when Expansion Racks are used (CPU
interface registers).

These registers can be read in programs but they
cannot be written.
The values are set from the MPE720.
