Features :

 

  • Please refer to the overview page for features of this product.
  • 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.

User programs that contain functions supported only by CPU Units with unit version 2.0 or later cannot be used on CS/CJ-series Pre-Ver. 2.0 CPU Units. An error message will be displayed if an attempt is made to download programs containing unit version s.0 functions to a Pre-Ver. 2.0 CPU Unit, and the download will not be possible.
If an object program file (.OBJ) using these functions is transferred to a Pre- Ver. 2.0 CPU Unit, a program error will occur when operation is started or when the unit version 2.0 function is executed, and CPU Unit operation will stop.

 

 

Unit Versions and Programming Devices

The following tables show the relationship between unit versions and CX-Programmer versions.

Note:

  1. As shown above, there is no need to upgrade to CX-Programmer version as long as the functions added for unit versions are not used.
  2. CX-Programmer version 7.1 or higher is required to use the new functionality of CJ1-H-R CPU Units. When using CJ1-H-R CPU unit Ver.4.1, use CX-Programmer Ver.7.2 or later (Check the CX-Programmer version in "Version Information").
  3. CX-Programmer version 7.0 or higher is required to use the functional improvements made for unit version 4.0 of the CS/CJ-series CPU Units. With CX-Programmer version 7.2 or higher, you can use even more expanded functionality.
