DeviceNet Area
The DeviceNet Area consists of 600 words from CIO 3200 to CIO 3799.
Words in the DeviceNet Area are allocated to Slaves for DeviceNet remote I/O
communications. The DeviceNet Area is not used for the CPM1A-DRT21
Expansion Unit.
Words are allocated to Slaves using fixed allocations according to fixed allo-
cation settings 1, 2, and 3. One of these fixed areas must be selected.
The following words are allocated to the DeviceNet Unit when the remote I/O
slave function is used with fixed allocations.
The DeviceNet Area can be used in programming if a CJ-series DeviceNet
Unit is not used.
Forcing Bit Status
Bits in the DeviceNet Area can be force-set and force-reset.
Note There are two ways to allocated I/O in DeviceNet networks: Fixed allocations
according to node addresses and user-set allocations.
• With fixed allocations, words are automatically allocated to the slaves in
the specified fixed allocation area according to node addresses.
• With user-set allocations, the user can allocate words to Slaves from the
following words.
CIO 0 to CIO 235, CIO 300 to CIO 0511, CIO 1000 to CIO 1063
W0 to W511
H0 to H511
D0 to D32767
For details on word allocations, refer to the DeviceNet Operation Manual
(W267).

With fixed allocation, words are assigned according to node
numbers. (If a Slave requires two or more words, it will be
allocated as many node numbers as words required.)
