CIO (Core I/O) Area
(Core I/O) Area, Work
Areas
Holding Area
Auxiliary Area
Temporary Relay (TR) Area
Timer Area
Counter Area
I/O Area
5,120: CIO 000000 to CIO 031915 (320 words from CIO 0000 to CIO 0319)
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 Modules (CS1--Series Basic I/O Modules).
Data Link Area
3,200 (200 words): CIO 10000 to CIO 119915 (words CIO 1000 to CIO 1199)
Link bits are used for data links and are allocated to Modules in Controller Link
Systems
CPU Bus Unit Area 6,400 (400 words): CIO 150000 to CIO 189915 (words CIO 1500 to CIO 1899)
CPU Bus Unit bits can be used to store the operating status of CPU Bus Units.
(25 words per Unit, 16 Units max.)
Special I/O Module
Area
15,360 (960 words): CIO 200000 to CIO 295915 (words CIO 2000 to CIO 2959)
Special I/O Module bits can be allocated to CS1-Series Special I/O Modules.
(10 words per Unit, 96 Units max.)
CS1-Series
DeviceNet Area
9,600 (600 words): CIO 320000 to CIO 379915 (words CIO 3200 to CIO 3799)
CS1-Series DeviceNet Area bits are allocated to Slaves according to
CS1W-DRM21
DeviceNet Module remote I/O communications.
Fixed Allocations 1: Output 3200 to 3263
Input: 3300 to 3363
Fixed Allocations 2: Output 3400 to 3463
Input: 3500 to 3563
Fixed Allocations 3:Output 3600 to 3663
Input: 3700 to 3763
The following words are allocated in the Master even when fixed allocations are
used for the remote I/O communications Slave functions of a CS1-Series
DeviceNet Module (CS1W-DRM21).
Fixed Allocations 1: To Slave: Output 3370
To Master: Input: 3270
Fixed Allocations 2: To Slave:Output 3570
To Master: input: 3400
Fixed Allocations 3: To Slave:Output 3770
To Master: input: 3670
Internal I/O Area
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 programming to control
program execution. They cannot be used for external I/O.
Work Area
8,192 bits (512 words): W00000 to W51115 (W000 to W511)
These bits are used to control the programs only. (I/O from external I/O is not
possible.)
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.
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 for specific functions.
6 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)
