CJ1H-CPU67H-R
CJ1M-CPU12
Features
• Compact 90 × 65 mm (H × D) dimensions are first class in the industry.
• Provides excellent high-speed control performance, with high-speed processing of 16 ns for LD instructions and 0.24 μs for floating-point
calculations.
• A wide range of models is available, from the high-end models (2,560 points and 250K steps of program capacity) to basic models (160 points
and 5K steps).
• Other models are available with special functions such as the CJ1M-CPU2@, which provides positioning functions and built-in I/O, and the
CJ1G-CPU4@P.
• High-capacity Memory Cards up to 128 MB can be installed, and used to backup the program and system settings, or log customer data.
• The large instruction set can support diverse applications. Four types of programming are supported (ladder, structured text, sequential function
charts, and instruction lists), with approximately 400 instructions and 800 instruction variations.
• These CJ-series CPU Units support structured programming using function blocks, which can improve the customer's program development
resources.
• The various protection functions provide improved security to protect valuable software resources and property.
• The CPU Units are compatible with the CX-One Integrated Tool Package. Information for each component can be linked, and the system's data
can be integrated into one database. The software can provide total support from PLC settings to network startup.

Specifications
1 to 32,000 ms (Unit: 1 ms)
When a Parallel Processing Mode is used for a CJ1-H CPU Unit, the cycle time for executing instructions is constant.
Possible (Unit stops operating if the cycle is too long): 10 to 40,000 ms (Unit: 10 ms)
When a Parallel Processing Mode is used for a CJ1-H CPU Unit, the instruction execution cycle is monitored. CPU Unit
operation will stop if the peripheral servicing cycle time exceeds 2 s (fixed).
Cyclic refreshing, immediate refreshing, refreshing by IORF(097).
IORF(097) refreshes I/O bits allocated to Basic I/O Units and Special I/O Units.
With CJ1-H-R CPU Units the SPECIAL I/O UNIT I/O REFRESH instruction (FIORF(225)) can be used to refresh Special I/O
Units whenever required (including allocated DM Area words).
With the CJ1-H and CJ1M CPU Units, the CPU BUS UNIT I/O REFRESH (DLNK(226)) instruction can be used to refresh bits
allocated to CPU Bus Units in the CIO and DM Areas whenever required.
Data links for Controller Link Units and SYSMAC LINK Units, remote I/O for DeviceNet Units, and other special refreshing for
CPU Bus Units is performed at the following times:
• CJ1 CPU Units: I/O refresh period
• CJ1-H and CJ1M CPU Units: I/O refresh period and when the CPU BUS UNIT I/O REFRESH (DLNK(226)) instruction is
executed.
Depends on the ON/OFF status of the IOM Hold Bit in the Auxiliary Area.
All outputs on Output Units can be turned OFF when the CPU Unit is operating in RUN, MONITOR, or PROGRAM mode.
• CJ1-H and CJ1M CPU Units: BCD or binary (CX-Programmer Ver. 3.0 or higher).
• CJ1 CPU Units: BCD only.
Time constants can be set for inputs from Basic I/O Units. The time constant can be increased to reduce the influence of noise
and chattering or it can be decreased to detect shorter pulses on the inputs.
Possible (By default, the CPU Unit will start in RUN mode if a Programming Console is not connected.)
The user program and parameter area data (e.g., PLC Setup) are always backed up automatically in flash memory. (automatic
backup and restore.)
• CPU Units with unit version 3.0 or later only:
When downloading projects from CX-Programmer Ver. 5.0 or higher, symbol table files (including CX-Programmer symbol names,
I/O comments), comment files (CX-Programmer rung comments, other comments), and program index files (CX-Programmer
section names, section comments, or program comments) are stored in comment memory within the flash memory.
Automatically reading programs (autoboot) from the Memory
Card when the power is turned ON.
Possible
Program replacement during PLC operation
Possible
Format in which data is stored in Memory Card
User program: Program file format
PLC Setup and other parameters: Data file format
I/O memory: Data file format (binary format), text format, or
CSV format
Functions for which Memory Card read/write is supported
User program instructions, Programming Devices (including
CX-Programmer and Programming Consoles), Host Link
computers, AR Area control bits, easy backup operation
Memory Card data and the EM (Extended Data Memory) Area can be handled as files.
Control set/reset, differential monitoring, data tracing (scheduled, each cycle, or when instruction is executed), instruction error
tracing, storing location generating error when a program error occurs.
When the CPU Unit is in MONITOR or PROGRAM mode, multiple program sections ("circuits") of the user program can be
edited together. This function is not supported for block programming areas.
(With the CX-Programmer is used, multiple program sections of the user program can be edited together. When a Programming
Console is used, the program can be edited in mnemonics only.)
Overwrite protection: Set using DIP switch.
Copy protection: Password set using CX-Programmer or Programming Consoles.
User-defined errors (i.e., user can define fatal errors and non-fatal errors)
The FPD(269) instruction can be used to check the execution time and logic of each programming block.
FAL and FALS instructions can be used with the CJ1-H and CJ1M CPU Units to simulate errors.
Up to 20 errors are stored in the error log. Information includes the error code, error details, and the time the error occurred.
A CJ1-H or CJ1M CPU Unit can be set so that user-defined FAL errors are not stored in the error log.
Built-in peripheral port: Programming Device (including Programming Console) connections, Host Links, NT Links Built-in RS-
232C port: Programming Device (excluding Programming Console) connections, Host Links, no-protocol communications,
NT Links, Serial Gateway (Compoway/F master)
Serial Communications Unit (sold separately): Protocol macros, Host Links, NT Links, Modbus-RTU slave, No-protocol,
Serial Gateway (Compoway/F master, Modbus master)
Provided on all models.

Note: Used to store the time when power is turned ON and when errors occur.
AC Power Supply Unit: 10 to 25 ms (not fixed)
DC Power Supply Unit PD025: 2 to 5 ms; PD022: 2 to 10 ms
0 to 10 ms (user-defined, default: 0 ms)
Note: Not supported when the CJ1W-PD022 Power Supply Unit is mounted.
Held Areas: Holding bits, contents of Data Memory and Extended Data Memory, and status of the counter Completion Flags
and present values.
Note: If the IOM Hold Bit in the Auxiliary Area is turned ON, and the PLC Setup is set to maintain the IOM Hold Bit status when
power to the PLC is turned ON, the contents of the CIO Area, the Work Area, part of the Auxiliary Area, timer Completion
Flag and PVs, Index Registers, and the Data Registers will be saved for up to 20 days.

User programs that contain functions supported only by CPU Units with unit version 3.0 or later cannot be used on CS/CJ-series CPU Units with
unit version 2.0 or earlier. An error message will be displayed if an attempt is made to download programs containing unit version 3.0 functions to
a CPU Unit with a unit version of 2.0 or earlier, and the download will not be possible.
If an object program file (.OBJ) using these functions is transferred to a CPU Unit with a unit version of 2.0 or earlier, a program error will occur
when operation is started or when the unit version 3.0 function is executed, and CPU Unit operation will stop.
