It enables operators, engineers, and maintenance teams to access real-time process data, alarms, trends, diagnostics, and documentation through one centralized interface. The system is built on object-oriented technology, where every plant asset—such as motors, valves, pumps, and controllers—is represented as an object containing all related information, including graphics, control logic, maintenance data, and historical records. This structure enhances engineering efficiency, simplifies lifecycle management, and improves decision-making. ABB 800xA supports scalable architectures ranging from small facilities to large, multi-site industrial complexes, offering redundancy, high availability, and secure networking. It is widely used in industries such as oil and gas, power generation, chemicals, pharmaceuticals, and water treatment.
