Ladder diagram
1 to 7 steps per instruction
Approx. 400 (3-digit function codes)
Basic instructions: 0.02 µs min., Special instructions: 0.04 µs min.
288 (256 of which are also used as interrupt tasks)
Cyclic tasks are executed each cycle and are controlled with TKON(820) and TKOF(821) instructions.
The following 4 types of interrupt tasks are supported: Power OFF tasks:1 max., Scheduled interrupt
tasks: 2 max., I/O interrupt tasks: 32 max., External interrupt tasks: 256 max.
Scheduled Interrupts: Interrupts generated at a time s’cheduled by CPU’s built-in timer.
I/O Interrupts: Interrupts from Interrupt Input Modules.
Power OFF Interrupts: Interrupts executed when the CPU’s power is turned OFF.
External I/O Interrupts: Interrupts from Special I/O Modules, CS1 Special Modules, or Inner Board.
5,120 : CIO 000000 to CIO 031915 (320 words from CIO 0000 to CIO 0319 )
Setting of first rack words can be changed from default (CIO 0000) so that CIO 0000 to CIO 0999 can be
used.
I/O bits are allocated to Basic I/O Modules, such as CS1 Basic I/O Modules, C200H Basic I/O Modules,
and C200H Group-2 High-density I/O Modules.
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 and PC Link
Systems.
6,400 (400 words): CIO 150000 to CIO 189915 (words CIO 1500 to CIO 1899 )
CS1 CPU Bus Module bits store operating status of CS1 CPU Bus Modules. (25 words per Module, 16
Modules max.)
15,360 (960 words): CIO 200000 to CIO 295915 (words CIO 2000 to CIO 2959 )
Special I/O Module bits are allocated to CS1 Special I/O Modules and C200H Special I/O Modules. (See
Note.)
(10 words per Module, 96 Modules max.) The maximum number of slots, however, is limited to 80
including expansion slots, so maximum number of Modules is actually 80.)

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.)
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
Modules. (10 words per Rack, 5 Racks max.)
512 (32 words): CIO 310000 to CIO 313115 (words CIO 3100 to CIO 3131 )
I/O Terminal bits are allocated to I/O Terminal Modules (but not to Slave Racks) connected to SYSMAC
BUS Remote I/O Master Modules. (1 word per Terminal, 32 Terminals max.)
8,196 (512 words): CIO 000000 to CIO 051115 (words CIO 0000 to CIO 0511)
C200H Special I/O Module bits are allocated to C200H Special I/O Modules and allow access separate
from I/O refreshing.
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.
64 bits (4 words): CIO 027400 to CIO 025015 (words CIO 0247 to CIO 0250)
When a PC Link Module is used in a PC Link, use these bits to monitor PC Link errors and operating
status of other CPUs in PC Link.
