Information About CJ2H-CPU66
The CJ2H-CPU66 is a flagship CPU unit from Omron’s CJ2H series, engineered for fast, large-scale automation control. With a 150K-step program capacity, 352K words of data memory, and 10 banks of 32K-word EM memory, it’s built to manage highly complex applications with large data handling needs. This CPU supports up to 40 expansion units and three expansion racks, offering flexibility for modular growth in both machine and process control. Programming is available in ladder diagram (LD), structured text (ST), and sequential function chart (SFC), making it suitable for advanced industrial automation environments requiring speed, precision, and system-wide diagnostics.
Key Features:
-
150K-Step Program Capacity: Handles large control programs with advanced logic structures for complex systems.
-
352K Words of Data Memory + EM Banks: Includes 10 banks of 32K-word extended memory for efficient data storage and retrieval.
-
Ultra-Fast Instruction Execution: Executes basic instructions at 0.016 µs, enabling high-speed control loops and real-time responsiveness.
-
Massive I/O Scalability: Supports up to 2,560 local I/O points and 40 expansion units for large control system deployments.
-
Dual Communication Ports: Includes RS-232C for serial devices and USB for programming and configuration.
-
Advanced Programming Languages: Supports LD, ST, and SFC for flexible and structured program development.
-
High Task Handling: Manages up to 384 cyclic and interrupt tasks with fast 11 µs task return response.
-
Robust Diagnostics and Error Detection: Monitors power, memory, I/O, and instruction errors for secure and dependable operation.
The CJ2H-CPU66 delivers the reliability and precision required for high-speed, data-intensive PLC control in distributed industrial automation systems.
