ABB LD800HSE

The ABB LD800HSE is a FOUNDATION™ Fieldbus Linking Device designed to connect up to four FF H1 fieldbus segments to a High-Speed Ethernet (HSE) backbone network. It serves as a communication gateway between intelligent field instruments and higher-level control systems such as ABB's ABB Ability System 800xA.

Key Features

• Connects up to four independent FOUNDATION Fieldbus H1 links to a single HSE subnet.
• Functions as the Link Active Scheduler (LAS) and System Management Time Publisher for each H1 segment.
• Supports transparent configuration and diagnostics of connected field devices from the host system.
• Enables cyclic and acyclic data exchange between H1 devices and HSE hosts.
• Supports redundant operation using paired LD800HSE units for high availability applications.
• Allows republishing of process data between H1 segments and between H1 and HSE networks.
• Firmware can be updated remotely via download.

Technical Specifications

Applications

The LD800HSE is widely used in:

• Oil & Gas production and refining
• Chemical and petrochemical plants
• Power generation facilities
• Water and wastewater treatment
• Pulp & paper industries
• Pharmaceutical manufacturing
• Food & beverage processing
• Large-scale process automation systems utilizing FOUNDATION Fieldbus technology

Advantages

• Simplifies integration of FOUNDATION Fieldbus devices into DCS and SCADA systems.
• Improves network reliability through redundancy support.
• Reduces engineering and maintenance effort with centralized device management.
• Supports distributed control architectures and advanced diagnostics.
• Provides seamless communication between field instruments and enterprise-level automation systems.

Conclusion

The ABB LD800HSE is a robust industrial communication gateway that bridges FOUNDATION Fieldbus H1 networks with HSE Ethernet infrastructure. Its support for four H1 segments, redundant configurations, advanced diagnostics, and seamless integration with ABB automation platforms makes it an ideal solution for demanding process control environments requiring high reliability and efficient field device management.
