Main Features and Advantages
Four Independent H1 Links with Full LAS Functionality: The ABB 3BDH000320R02 supports up to four electrically isolated FF-H1 links, each operating as an independent Link Master with full Link Active Scheduler (LAS) functionality. This enables the ABB LD800HSE to schedule publisher/subscriber communication, manage token passing, and maintain deterministic data exchange across each H1 segment. The device supports republishing of process data from one H1 link to another or from H1 to HSE, providing flexible data distribution without requiring IEC 61131 controller configurations.
Seamless Host System Integration and Transparent Configuration: The ABB 3BDH000320R02 enables transparent configuration of connected H1 devices directly from the host system, allowing engineering personnel to configure, monitor, and diagnose field instruments through the 800xA environment without needing separate configuration tools. The ABB LD800HSE supports client/server access to function blocks in H1 devices and distributes reports and alarms from the field level to management consoles. This tight integration significantly reduces engineering effort and commissioning time for new installations.
High Availability through Redundancy: The ABB 3BDH000320R02 is engineered for mission-critical applications through its support for device redundancy. Two ABB LD800HSE units can be connected to the same H1 links, with a dedicated serial redundancy link between primary and secondary devices ensuring reliable failover and continuous monitoring of redundancy status. This capability is essential for applications where uninterrupted fieldbus communication is required to maintain process safety and production continuity, such as burner management systems and emergency shutdown networks.
Robust Industrial Design and Diagnostics: The ABB 3BDH000320R02 features a rugged DIN-rail-mountable enclosure rated IP20, with G3 coating compliant with ISA 71.04 for corrosion protection in harsh industrial environments. Onboard status and error displays provide immediate visual feedback on device health, H1 link status, and redundancy state, enabling rapid field troubleshooting. The ABB LD800HSE supports firmware updates via download, allowing facilities to implement bug fixes and feature enhancements without hardware replacement
