Description

The ABB CP800 is a high-performance compact PLC controller designed for cost-effective automation in mid-range applications. As the core of ABB’s Compact Product Suite, this versatile controller delivers robust processing power in a space-optimized DIN-rail mountable package. The ABB CP800 executes complex control strategies with its 32-bit ARM Cortex processor running CODESYS V3.5 runtime, supporting IEC 61131-3 programming languages including ladder logic, structured text, and function block diagrams. Engineered for seamless integration, it features embedded Ethernet TCP/IP (Modbus TCP) and serial ports (RS-232/485) for SCADA connectivity and device networking.

With SIL 2 safety certification (IEC 61508), the ABB CP800 enables safety functions like emergency stops without additional hardware. Its modular design supports local I/O expansion via SD800 series modules and integrates with ABB drives via built-in Modbus RTU. The controller operates reliably in -25°C to +60°C environments with 95% humidity tolerance, making it ideal for HVAC, water treatment, and packaging machinery. Real-time clock, SD card backup, and 16 MB user memory ensure data integrity during power cycles.

Technical Specifications

Main Features and Advantages

Integrated safety and connectivity:
The ABB CP800 eliminates need for safety relays with certified SIL 2 functions (STO, SS1). Dual serial ports enable simultaneous HMI communication and drive control via Modbus RTU. Built-in webserver allows remote diagnostics without engineering software.

Scalable I/O architecture:
Support for 8 local expansion modules (SD800 series) enables flexible configuration. Hot-swappable I/O cards reduce downtime during maintenance. MicroSD slot stores program backups and data logs for quick recovery.

Engineering efficiency:
Programmable via CODESYS IDE with ABB-specific libraries for motion control and energy management. Automatic device replacement (ADR) feature clones configurations to replacement units in minutes.

Application Field

The ABB CP800 excels in distributed control applications requiring compact footprints. In water treatment plants, it manages pump sequencing and chemical dosing via Modbus-connected instruments. For HVAC systems, it coordinates chillers and air handlers with PID loop control.

Manufacturing lines deploy it for conveyor synchronization and robotic cell interfacing. Renewable energy applications include solar tracker positioning and wind turbine pitch control. The ABB CP800 also serves building automation (lighting/access control) and material handling systems where SIL 2 safety interlocks are mandated.
