Allocate the DeviceNet read and write areas to specify what part of the PC's
data area will be used to read and write data from the DeviceNet Master Unit.
Specify the PC data area, starting word address, and number of bytes. Up to
64 bytes can be allocated for DeviceNet remote I/O.

such as a Programming Console or Support Software, to make the following
settings in DM 6605 to DM 6609 of the PC Setup. The settings in these words
are read only when the CPM2C-S is turned ON, so the PC's power must be
