What is ABB System 800xA?
The complete guide to ABB's enterprise-level distributed control system for large-scale industrial automation.
Quick Answer
ABB System 800xA is an enterprise-level distributed control system (DCS) that integrates process control, electrical control, safety systems, and asset management into a unified platform. It uses AC800M controllers (M-line) and is designed for large, complex facilities in industries like oil & gas, power generation, and chemicals. System 800xA supports thousands of I/O points, multi-site operations, and comprehensive third-party integration.
System 800xA Overview
System 800xA represents ABB's flagship automation platform, introduced in 2004 as the evolution of the Advant OCS and Industrial IT platforms. The "xA" stands for "Extended Automation," reflecting its philosophy of integrating all aspects of plant automation—process control, electrical systems, safety, and telecommunications—into one cohesive system.
Unlike traditional DCS platforms that focus solely on process control, System 800xA provides a single engineering environment for all automation disciplines. This integration reduces complexity, lowers lifecycle costs, and improves operational efficiency for large industrial facilities.
Key Capabilities
Integrated Engineering
Single engineering environment for process control, electrical systems, drives, instrumentation, and safety—eliminating integration gaps between disciplines.
Enterprise Scalability
Supports facilities from hundreds to hundreds of thousands of I/O points, with multi-site coordination for enterprise-wide visibility and control.
Integrated Safety
SIL 2/3 certified safety system integrated with process control, providing unified operator interface for both normal operations and emergency response.
Asset Management
Built-in asset optimization with predictive maintenance, device diagnostics, and performance monitoring across all connected equipment.
Open Connectivity
Extensive protocol support: OPC, Modbus, PROFIBUS, PROFINET, FOUNDATION Fieldbus, HART, IEC 61850 for electrical integration.
Global Operations
Multi-site architecture enables centralized monitoring and management of geographically distributed facilities from a single control room.
The AC800M Controller
System 800xA is built around the AC800M controller, ABB's M-line (Master line) processor that superseded the AC450 from the Advant Master system. The "M" designates this as the enterprise/master controller family, distinct from the F-line (Freelance) controllers.
