Specification
9,600 (600 words): CIO 320000 to CIO 379915 (words
CIO 3200 to CIO 3799)
CS-series DeviceNet Area bits are allocated to Slaves
according to C200HW-CRW21-V1 DeviceNet Unit remote I/O
communications.
Fixed allocation 1 Outputs: CIO 3200 to CIO 3263
Inputs: CIO 3300 to CIO 3363
Fixed allocation 2 Outputs: CIO 3400 to CIO 3463
Inputs: CIO 3500 to CIO 3563
Fixed allocation 3 Outputs: CIO 3600 to CIO 3663
Inputs: CIO 3700 to CIO 3763
The following words are allocated to the CS-Series
DeviceNet Unit functioning as a master when fixed alloca-
tions are used for the CS1W-DRM21 DeviceNet Unit.

4,800 (300 words): CIO 120000 to CIO 149915 (words CIO
1200 to CIO 1499)
37,504 (2,344 words): CIO 380000 to CIO 614315 (words
CIO 3800 to CIO 6143)
These bits in the CIO Area are used as work bits in program-
ming to control program execution. They cannot be used for
external I/O.
8,192 bits (512 words): W00000 to W51115 (W000 to W511)
Controls the programs only. (I/O from external I/O terminals is
not possible.)
Note When using work bits in programming, use the bits in
the Work Area first before using bits from other areas.
8,192 bits (512 words): H00000 to H51115 (H000 to H511)
Holding bits are used to control the execution of the program,
and maintain their ON/OFF status when the PLC is turned
OFF or the operating mode is changed.
Note The Function Block Holding Area words are allocated
from H512 to H1535. These words can be used only
for the function block instance area (internally allocated
variable area).
Read only: 7,168 bits (448 words): A00000 to A44715 (words
A000 to A447)
Read/write: 8,192 bits (512 words): A44800 to A95915
(words A448 to A959)
Auxiliary bits are allocated specific functions.
16 bits (TR0 to TR15)
Temporary bits are used to temporarily store the ON/OFF
execution conditions at program branches.
4,096: T0000 to T4095 (used for timers only)
4,096: C0000 to C4095 (used for counters only)
