CPU Overview
CS1 CPU Specifications
Common Specifications (continued)
Item
Internal I/O Area
Specification
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)
Work Area
These bits in CIO Area are used as work bits in programming to control program execution. They cannot
be used for external I/O.
8,192 bits (512 words): W00000 to W51115 (words W000 to W511)
Control programs only. (I/O from external I/O terminals is not possible.)
Note: When using work bits in programming, use bits in Work Area first before using bits from other
areas.
Holding Area
8,192 bits (512 words): H00000 to H51115 (words H000 to H511)
Auxiliary Area
Holding bits are used to control execution of program, and maintain their ON/OFF status when PLC is
turned OFF or 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 specific functions.
Temporary Area
16 bits (TR00 to TR15) Temporary bits are used to store ON/OFF execution conditions at program
branches.
Timer Area
Counter Area
DM Area
4,096: T0000 to T4095 (used for timers only)
4,096: C0000 to C4095 (used for counters only)
32K words: D00000 to D32767
Used as a general-purpose data area for reading and writing data in word units (16 bits). Words in DM
Area maintain their status when PLC is turned OFF or operating mode is changed.
Internal Special I/O Module DM Area: D20000 to D29599 (100 words × 96 Units). Used to set
parameters.
EM Area
CS1 CPU Bus Module DM Area: D30000 to D31599 (100 words × 16 Units). Used to set parameters.
Inner Board DM Area: D32000 to D32099. Used to set parameters for Inner Boards.
32K words per bank, 13 banks max.: E0_00000 to EC_32767 max. (Not available on some CPU.)
Used as a general-purpose data area for reading and writing data in word units (16 bits). Words in EM
Area maintain their status when PLC is turned OFF or operating mode is changed.
The EM Area is divided into banks, and addresses can be set by either of following methods.
Changing current bank using EMBC(281) instruction and setting addresses for current bank.
Setting bank numbers and addresses directly.
Data Registers
EM data can be stored in files by specifying number of first bank. (EM file memory)
DR0 to DR15. Store offset values for indirect addressing. Data registers can be used independently in
each task. One register is 16 bits (1 word).
Index Registers
IR0 to IR15. Store PLC memory addresses for indirect addressing. Index registers can be used
independently in each task. One register is 32 bits (2 words).
Task Flag Area
32 (TK0000 to TK0031). Task Flags are read-only flags that are ON when corresponding cyclic task is
executable and OFF when corresponding task is not executable or in standby status.
Trace Memory
File Memory
4,000 words (500 data trace samples at the maximum sample size of 31 bits and 6 words)
Memory Cards: Compact flash memory cards can be used (MS-DOS format).
EM file memory: Part of EM Area can be converted to file memory (MS-DOS format).
OMRON Memory Cards with 8-MB, 15-MB, 30-MB, or 48-MB capacities can be used.
Note: A maximum of 10 or 16 C200H Special I/O Modules can be used depending on the CPU. Some I/O Modules are Special I/O
Modules.
