(Core
I/O)
Area
I/O Area 1,280: CIO 000000 to CIO 007915 (80 words from CIO
0000 to CIO 0079)
The setting of the first word can be changed from the
default (CIO 0000) so that CIO 0000 to CIO 0999 can be
used.
I/O bits are allocated to Basic I/O Units.
The CIO
Area can
be used
as work
bits if the
bits are
not used
as shown
here.

Area
DeviceNet Area 9,600 (600 words): CIO 320000 to CIO 379915 (words CIO
3200 to CIO 3799)
DeviceNet bits are allocated to Slaves for DeviceNet Unit
remote I/O communications when the Master function is
used with fixed allocations.
The following words are allocated to the Master function
even when the DeviceNet Unit is used as a Slave.
