The ABB LD800HSE, part number 3BDH000320R0101, is a high-performance communication gateway designed for the integration of field-level data into high-level control networks. It serves as a bridge between FOUNDATION Fieldbus H1 segments and the High Speed Ethernet (HSE) backbone, enabling seamless data flow within the ABB Ability™ System 800xA and other compatible DCS environments.
Product Datasheet & Parameters
The following specifications define the technical framework and networking capabilities of the LD800HSE.
Product Technical Description
The LD800HSE is a critical infrastructure component for plants utilizing fieldbus technology. It handles the mapping of real-time process variables, alarms, and diagnostic data from complex field instruments to the central control system.
Key Technical Attributes:
-
Multi-Segment Management: A single device can manage up to four independent H1 segments, significantly reducing the hardware footprint in the control cabinet.
-
Redundancy Support: Fully supports redundant configurations to ensure that communication remains active even if one linking device or network path fails.
-
Deterministic Communication: Implements the scheduling and time-synchronization required by the FOUNDATION Fieldbus standard, ensuring that control loops are executed with precise timing.
-
High Bandwidth Backbone: By converting H1 data (31.25 kbps) to HSE (100 Mbps), it ensures that the high-level network is never bottlenecked by field-level data transmission.
-
Diagnostic Transparency: Provides detailed status information for each connected H1 segment, allowing for rapid troubleshooting of field wiring or device health.
Country of Origin
-
Origin: Germany (DE)
Note: The LD800HSE series is primarily engineered and manufactured at ABB’s industrial automation and communication centers in Germany, ensuring compliance with global networking standards.
Common Questions & Answers (Q&A)
Q: Does the LD800HSE provide power to the H1 segments? A: No. The LD800HSE is a communication device. Power for the H1 segments must be provided by separate, external Fieldbus Power Supplies and Power Conditioners.
Q: Can this linking device be used with non-ABB DCS systems? A: Yes. Since it follows the open FOUNDATION Fieldbus HSE standard, it can be integrated into any control system that supports the HSE protocol and Linking Device standard.
Q: How is the LD800HSE configured? A: Configuration is typically performed via the system’s engineering station (such as the 800xA Fieldbus Builder). It involves setting the IP address for the HSE side and configuring the schedule for the H1 segments.
