Omron C200HS-CPU01-E SYSMAC Programmable Controller

The Omron C200HS-CPU01-E is a CPU unit for the C200HS SYSMAC programmable logic controller series. This compact controller provides program execution, I/O control, and communication functions for small to medium automation systems. It is widely used in legacy industrial machines, conveyor systems, and packaging equipment.

Program Memory and Execution

The CPU has a user program capacity of 7.2K steps (RAM, battery-backed). Basic instruction execution time is 0.5 µs; special instructions average 10 µs. The instruction set includes 132 types (basic, arithmetic, compare, shift, data transfer). The CPU supports up to 4 program files and 40 interrupt tasks.

I/O Capacity and Expansion

Maximum I/O points: 880 (using local expansion racks). The base CPU can directly mount up to 10 I/O modules on the main rack (up to 10 slots). Two expansion racks can be added via a cable, each holding up to 10 modules. The CPU supports digital, analog, temperature, and high-speed counter modules.

Built-in Communication

The C200HS-CPU01-E includes one RS-232C port (9-pin D-sub) for connection to a programming console, PC (CX-Programmer software), or HMI. It supports Omron’s Host Link protocol (SYSMAC WAY) at baud rates up to 19.2 kbps. An optional RS-422 adapter allows longer distance wiring.

Memory and Battery Backup

User program and data memory are retained by a lithium battery (type C200H-BAT01). Battery life is approximately 5 years under normal conditions. The CPU has a battery low LED and a built-in capacitor that retains memory for up to 10 minutes during battery change. A memory cassette slot allows expansion using EEPROM or UVEPROM cassettes.

Diagnostic and Status LEDs

Front panel indicators: POWER (green), RUN (green), ERR/ALM (red), COMM (yellow flash for RS-232 activity). The CPU includes a self-diagnosis function that checks for CPU error, I/O verification error, and battery low. A watchdog timer (30 ms to 13 ms selectable) monitors execution time.

Physical and Environmental

Dimensions: 130 x 110 x 65 mm (W x H x D). Weight 0.5 kg. Power supply is provided via the C200H-PS-series power supply module (sold separately). Operating temperature: 0°C to 55°C; storage: -20°C to 75°C. Humidity: 30% to 90% non-condensing.

Applications

Commonly found in legacy packaging lines, labeling machines, small conveyors, and sorting systems. The C200HS-CPU01-E is also used as a replacement part for existing installations.

Conclusion

The Omron C200HS-CPU01-E provides reliable program execution, expandable I/O, and basic serial communication for the C200HS series. Its compact design and legacy support make it valuable for maintaining older automation systems.
