OMRON CS1H-CPU63-H CPU Unit: High-Performance PLC for Complex Automation

The OMRON CS1H-CPU63-H is a powerful CPU unit belonging to the CS1 series of programmable logic controllers. Designed for large-scale and high-speed control applications, this CPU features a 32-bit RISC processor, extensive program memory, and built-in I/O. It supports OMRON’s CX-Programmer software and offers advanced capabilities such as interrupt handling, high-speed counters, and motion control via optional units. The CS1H-CPU63-H is suitable for machine builders, process automation, and factory-wide control systems.

Processor and Memory Specifications

The CS1H-CPU63-H is equipped with a 32-bit RISC CPU (SH-2 core) running at 20 MHz, delivering a typical instruction execution time of 0.1 µs for basic logic and 1.2 µs for advanced instructions. It provides 60K steps (120K bytes) of user program memory (flash ROM) and 60K words of data memory (DM, EM). The built-in real-time clock with a 5-year battery backup supports time-stamped events. Up to 5120 I/O points can be controlled using expansion racks and remote I/O via SYSMAC BUS or DeviceNet.

Built-in I/O and Functions

The CPU unit itself includes 16 discrete inputs (24 VDC, sink/source) and 16 transistor outputs (sink type, 0.5A per point). Two high-speed counter inputs (phase A/B, up to 50 kHz) support encoder feedback for positioning applications. Additionally, two pulse outputs (up to 50 kHz) can control stepper or servo drives. The CS1H-CPU63-H also features four interrupt inputs with response times as low as 0.2 ms, ideal for emergency stop or high-speed event capture.

Communication Ports and Networking

Standard communication includes a built-in RS-232C port (for programming or host link) and a peripheral port (for CX-Programmer connection). The CPU supports optional communication boards (e.g., EtherNet/IP, Controller Link, Profibus-DP) that insert into the front panel. Using the SYSMAC LINK or Controller Link networks, multiple CS1 CPUs can be interconnected for distributed control. The CPU also supports protocol macros for communication with third-party devices (e.g., barcode readers, weigh scales).

Programming and Software

Programming is done via OMRON’s CX-Programmer (version 5.0 or higher) using ladder diagram, structured text, or sequential function chart (IEC 61131-3). The CS1H-CPU63-H supports function blocks, structured programming, and online editing. The CPU includes a real-time OS with multitasking capabilities, allowing up to 128 tasks. Built-in debugging tools include data tracing (2 channels, up to 1000 samples) and force set/reset functions.

Environmental and Power Specifications

The CPU unit requires 24 VDC power (20.4 to 28.8 V), consuming 400 mA typical. Operating temperature: 0°C to 55°C, storage -20°C to 75°C. Humidity: 10% to 90% non-condensing. The unit is designed for DIN rail mounting (35mm) with dimensions: 130mm (H) x 100mm (W) x 95mm (D). It meets UL508, CSA, CE, and NK (Nippon Kaiji Kyokai) standards. The battery (3.6V lithium) has a life of 5 years under normal use.

Typical Applications

The CS1H-CPU63-H is deployed in injection molding machines, packaging lines, material handling systems, and water treatment plants. Its high-speed counters and pulse outputs make it suitable for single-axis positioning without a dedicated motion module. With up to 5120 I/O, it can control large assembly lines with multiple stations. The CPU’s robust design and OMRON’s global support ensure reliable operation in 24/7 industrial environments.

Expansion and Compatibility

The CPU can be expanded with CS1 series I/O units (digital, analog, temperature, communication, motion) and can also control remote I/O via DeviceNet or CompoNet. It is backward compatible with C200H I/O modules using an adapter. The CS1H-CPU63-H is fully compatible with CX-One software suite, including CX-Simulator for offline debugging. For system upgrades, the same program can be used with newer CJ2 or NJ series CPUs with minor modifications.

Maintenance and Ordering

Order number: CS1H-CPU63-H. The unit includes the CPU, built-in I/O terminals, and an RS-232C port. A programming cable (CS1W-CN226) and CX-Programmer software are required separately. Battery replacement is recommended every five years. OMRON provides a comprehensive manual (Cat. No. W339) covering installation, programming, and troubleshooting. The CPU is RoHS compliant and designed for a service life of 10 years under specified conditions.
