Product Details
The ABB LD 810HSE EX, also cataloged as the LD 810HSE EX Communication Module, operates as a dedicated hardware component for fieldbus network linking and data conversion within ABB S900 IO hardware platforms. Mounted on a standard DIN rail, the module links four H1 field networks with a High Speed Ethernet (HSE) trunk, executing high-speed protocol conversion across Foundation Fieldbus architectures.

Backplane Bus Communication Velocity & I/O Density Scaling
The LD 810HSE EX linking device maintains backplane bus communication velocity across deterministic Ethernet and Foundation Fieldbus segments. By aggregating four separate H1 links into a single High Speed Ethernet port, the module optimizes cabinet I/O density scaling while isolating field communication signals. High-density firmware flash compatibility ensures synchronized parameter exchange across connected controller sub-racks without introducing network transmission bottlenecks.
Frequently Asked Questions
Q: Can the LD 810HSE EX be installed to replace a single LD 800 device in an existing redundant pair?
A: No. Mixing LD 800 and LD 810HSE EX modules in a single redundant pair is not supported; both units in a redundant pair must be replaced with LD 810HSE EX modules simultaneously.
Q: How is primary operating power delivered to the LD 810HSE EX module and its H1 links?
A: The module itself requires an external 24 VDC power supply connection, while all connected H1 fieldbus links must be powered independently via dedicated fieldbus power conditioners.
Q: How is the redundancy link cable provided for paired LD 810HSE EX installations?
A: The redundancy cable can be procured or fabricated directly by the customer according to standard Ethernet link specifications rather than requiring a proprietary factory cable.
Field Installation Guidelines
Follow these technical procedures during panel installation and field cabling:
- DIN-Rail Mounting: Snap the LD 810HSE EX securely onto a top-hat 35 mm DIN rail, verifying that the rear metal DIN clamp fully latches onto the rail edge.
- Earth Ground Bonding: Ensure the DIN rail surface is unpainted and directly bonded to the cabinet protective earth (PE) bus to establish shield termination ground paths for the HSE and H1 ports.
- Power Connection: Wire an isolated external 24 VDC power source to the module power terminals; confirm separate power supplies are configured for the H1 fieldbus segment conditioners.
- Network Cabling: Connect the HSE network cable to the primary Ethernet port and route shielded twisted-pair cables from the four H1 links, ensuring line termination resistors are active at both ends of each H1 segment.

Tech & Buying Guide
Why Programmable Logic Controllers Drop into Stop Mode: An Expert Analysis
Industrial automation systems rely heavily on Programmable Logic Controllers (PLCs) to maintain uninterrupted production. When a PLC unexpectedly shifts from Run to Stop mode, whole manufacturing lines stall.
As control systems evolve across modern factory automation, understanding the root causes of these interruptions helps engineers minimize costly downtime. This technical guide breaks down why PLCs trip into Stop mode and provides practical strategies to mitigate system faults.
Understanding Root Causes of Unplanned PLC Stop Mode in Industrial Automation
Modern Programmable Logic Controllers manage execution through distinct operational states: Run, Stop, Start-Up, and Hold. During power-up, a controller initializes memory registers within Stop mode before briefly transitioning to Start-Up mode. During this phase, internal self-diagnostics evaluate system integrity across hardware and user programs. If the controller detects no critical faults, it enters Run mode to execute the control program continuously. However, any severe system anomaly forces the CPU back into Stop mode immediately to prevent erratic machine behavior across the plant floor.
Human-Machine Interface Design: Essential Guide to HMI Selection, Visualization, and Control System Integration
Human-Machine Interfaces (HMIs) serve as the primary operational window into complex industrial automation systems. Modern HMIs convert raw machine data into clear graphical displays, enabling operators to oversee entire manufacturing processes in real time. Instead of relying on physical control panels full of hardwired switches, engineers program interactive screens using intuitive graphics, dynamic color coding, and responsive touch interfaces. Over my 15 years in control systems engineering, I have observed HMIs transform from basic display screens into sophisticated command centers that drive operational efficiency across DCS and PLC environments.
