Interrupt types |
Scheduled Interrupts: Interrupts generated at a time scheduled by the CPU Unit’s built-in timer. I/O Interrupts: Interrupts from Interrupt Input Units.
Power OFF Interrupts: Interrupts executed when the CPU Unit’s power is turned OFF. External I/O Interrupts: Interrupts from the Special I/O Units, CS-series CPU Bus Units, or the Inner Board. |

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. |
|

| 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)

|
| 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. |

|
| 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). |
