At ABB Ability ™  Integration in IT system (800xA system)

（1） System Architecture Role

In a typical 800xA system architecture, FOUNDATION ™  The Fieldbus subsystem is connected to the control system (such as the AC 800M controller) through the HSE subnet, with LD 810HSE Ex serving as the gateway to establish a communication bridge between the field devices on the H1 link and the HSE subnet. The specific architecture is as follows:

Upper level system: including engineering workstation (Control Builder M workstation), operator maintenance workstation, Fieldbus Builder FF client/server network, and connectivity server with OPC server (FF Connectivity Server).

Control layer: The AC 800M controller is connected to the HSE subnet through the communication interface module CI860 (as the HSE host) to achieve control and data exchange of the Fieldbus subsystem.

Fieldbus subsystem: composed of multiple LD 810HSE Ex linked devices and H1 field devices, the linked devices communicate through HSE protocol and manage the H1 links under them, realizing the forwarding of process data and device management.

（2） Key integration capabilities

Data exchange: With the help of HSE data forwarding function, periodic communication between different H1 link on-site devices and HSE subnet devices can be configured to meet real-time control requirements.

Alarm integration: The alarms and events of H1 devices are transmitted to the FF connectivity server through linked devices, seamlessly integrated into the alarm management system of the 800xA system for unified monitoring and processing.

Redundant configuration: Supports LD 810HSE Ex redundant deployment, where the corresponding H1 ports of two physically linked devices in the redundant group are connected to the same H1 link, and redundant control information is exchanged through redundant link wiring to enhance system reliability.
