The ABB LD800HSE 3BDH000320R02 is a communication gateway module in the FOUNDATION Fieldbus system. It complies with the 42c class standard of the FF HSE protocol and is used to connect the FF H1 fieldbus link with the FF HSE high-speed Ethernet subnet. It supports redundant configuration.
Core Functions:
Device Management: Identifies devices on the H1 link and enables system management (SM) and network management (NM) to configure and monitor H1 devices via HSE.
Data Interaction: Bidirectionally forwards process data (e.g., sensor signals, control commands) between H1 links and between H1 and HSE.
Distributes alarm and event information from H1 devices to the HSE network.
Time Synchronization: Acts as the Link Master for H1 links and the SM Time Publisher to ensure network-wide time synchronization.
Protocol Conversion: Supports protocol conversion between HSE and H1, enabling interoperability between devices at different network levels.
Technical Specifications:
Complies with Class 42c of the FF HSE protocol.
Connects FF H1 fieldbus links to FF HSE high-speed Ethernet subnets.
Redundancy configuration supported for high availability.
