ABB CP800

1. Overview

The ABB CP800 is a DIN rail-mounted compact auxiliary processor module dedicated to communication data processing within ABB industrial automation systems, mainly deployed between core DCS CPU, HMI touch panels, third-party PLCs and fieldbus instruments to undertake massive data transmission, protocol conversion and signal buffer scheduling work, reducing computing load of main control CPU and improving whole system operation efficiency. Built-in multiple independent 10/100Mbps Ethernet channels and isolated RS232/RS485 serial interfaces, supports Modbus RTU, TCP/IP, Profibus and other mainstream industrial communication protocols, realizing seamless data exchange between heterogeneous automation equipment. Compact small-size DIN rail design occupies minimal cabinet rack space, IP20 indoor cabinet protection grade, wide temperature working range -20℃ ~ +70℃, conformal coated circuit board for anti-corrosion workshop environment adaptation. Widely matched with AC800M DCS, Symphony and ABB PLC systems for power, water treatment, building automation and light industry process control projects.

3. Key Features

Specialized Communication Load Offloading: Undertakes mass data transmission and protocol conversion tasks, effectively reduces main DCS CPU operation load to avoid control logic delay. Multi-Channel Isolated Communication Interfaces: Independent isolated serial and Ethernet ports prevent ground loop interference between different automation subsystems, improving data transmission stability. Multi Industrial Protocol Native Support: Built-in mainstream Modbus, Profibus protocol stack, no extra gateway equipment required for cross-brand equipment interconnection. Ultra-Compact DIN Rail Structure: Small body saves valuable control cabinet rack space, suitable for compact integrated automation cabinet design. Wide Industrial Temperature Adaptation: -20℃ ~ +70℃ wide operating temperature range, applicable to unheated northern factory control rooms and high-temperature light industry workshops. Complete ABB Automation Ecosystem Matching: Seamless plug-and-play connection with AC800M CPU, S800 I/O and ABB HMI touch screens without driver adaptation.

4. Structure and Composition

The ABB CP800 adopts integrated compact PCB modular structure, integrating embedded communication processing core, multi-channel Ethernet switching circuit, isolated serial signal conditioning unit and 24VDC power filtering module. Front panel equipped with independent LED indicator lights for each communication channel, convenient for on-site engineers to quickly judge data transmission status and communication fault points. Standard 35mm DIN rail buckle design for fast cabinet mounting and disassembly; conformal coating treatment on all circuit boards to resist trace corrosive gas and damp air in industrial control rooms. Independent terminal wiring area for power and signal separation, avoiding mutual electromagnetic interference between power circuit and communication signal circuit.

5. Application Fields

• Power Plant Auxiliary Control Cabinets: Data forwarding between DCS main control unit, water supply and ash removal local PLC subsystems
• Water & Wastewater Treatment Automation: Communication gateway for flow meter, liquid level sensor and central HMI monitoring system
• Light Industry & Packaging Production Lines: Cross-data exchange between main PLC and multiple winding machine local controllers
• Building HVAC & Intelligent Energy Control: Fieldbus data scheduling for air-conditioning, water supply and power distribution monitoring systems
• Small-Scale Chemical Process Workshop: Compact cabinet communication buffer module for mini AC800M DCS control racks
