CIO (Core I/O)

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 Units, such as CS-series Basic I/O Units, C200H Basic I/O Units, and C200H Group-2

High-density I/O Units.

The CIO

Area can be

used as work

bits if the bits

are not used

as shown

here.

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 Units in Controller Link Systems and PLC Link Systems.

CPU Bus Unit Area

6.400 (400 words): CIO 150000 to CIO 189915 (words CIO 1500 to CIO 1899)

CS-series CPU Bus Unit bits store the operating status of CS-series CPU Bus Units.

(25 words per Unit, 16 Units max.)

Special I/O Unit Area

15.360 (960 words): CIO 200000 to CIO 295915 (words CIO 2000 to CIO 2959)

Special I/O Unit bits are allocated to CS-series Special I/O Units and C200H Special I/O Units. (See Note.)

(10 words per Unit, 96 Units max. The maximum total number of slots, however, is limited to 80 including expansion slots, so

the maximum number of Units is actually 80.

Note: A maximum of 16 C200H Special I/O Units can be mounted. Also, depending on the Units, the maximum may be 10.

Some I/O Units are classified as Special I/O Units.

Inner Board Area 1.600 (100 words): CIO 190000 to CIO 199915 (words CIO 1900 to CIO 1999)

Inner Board bits are allocated to Inner Boards. (100 I/O words max.)

SYSMAC BUS Area

800 (50 words): CIO 300000 to CIO 304915 (words CIO 3000 to CIO 3049)

SYSMAC BUS bits are allocated to Slave Racks connected to SYSMAC BUS Remote I/O Master Units. (10 words per Rack,

5 Racks max.)

I/O Terminal Area

512 (32 words): CIO 310000 to CIO 313115 (words CIO 3100 to CIO 3131)

I/O Terminal bits are allocated to I/O Terminal Units (but not to Slave Racks) connected to SYSMAC BUS Remote I/O

Master Units. (1 word per Terminal, 32 Terminals max.)

C200H Special I/O Unit

Area

8.192 bits (512 words): W00000 to W51115 (W000 to W511)

C200H Special I/O Unit bits are allocated to C200H Special I/O Units, and accessed separately from I/O refreshing.

DeviceNet Area

1.600 (100 words): Outputs: CIO 005000 to CIO 009915 (words CIO 0050 to CIO 0099)

Inputs: CIO 035000 to CIO 039915 (words CIO 0350 to CIO 0399)

DeviceNet bits are allocated to Slaves according to DeviceNet remote I/O communications.

PLC Link Area

64 bits (4 words): CIO 024700 to CIO 025015 (words CIO 0247 to CIO 0250)

When a PLC Link Unit is used in a PLC Link, use these bits to monitor PLC Link errors and the operating status of other

CPU Units in the PLC Link.

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): H00000 to H51115 (H000 to H511)

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.)

When using work bits in programming, use the bits in the Work Area first before using bits from other areas.

Holding Area

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).

Auxiliary Area
