        Features:

        • Four Independent H1 Link Masters (LAS)
        • Bumpless Serial Hardware Redundancy
        • Industrial G3 Conformal Chemical Coating
        The ABB LD800HSE acts as a Link Master for up to four isolated H1 channels simultaneously, ensuring highly reliable, deterministic scheduling of publisher/subscriber communication cycles directly at the field level.

        By linking a pair of ABB LD800HSE gateways via their dedicated RS-232 serial com ports, the system establishes active redundancy tracking that guarantees instant, bumpless failover without disrupting real-time field data or H1 cycles.

        The specialized ABB LD800HSE EX variant features standard G3-level ruggedized coating tested against ANSI/ISA 71.04 and EN 60068-2-60 protocols, preventing corrosion from moisture, salt air, and aggressive industrial gases.

        Description
        The ABB LD800HSE is engineered to function as a highly compact and reliable link between up to four independent FF H1 field networks running at 31.25 kbit/s and a high-speed 10/100 Mbit/s HSE subnet. By translating low-level instrumentation data into standardized Ethernet packets, the ABB LD800HSE allows supervisory management consoles and plant controllers to interact directly with sophisticated field devices without sacrificing communication bandwidth or data integrity. 

        Acting as a robust Link Active Scheduler (LAS) and SM Time Publisher for every connected H1 channel, the ABB LD800HSE ensures precise deterministic execution of publisher/subscriber communication cycles. It features advanced data republishing mechanisms that route critical process measurements directly from H1 to HSE or even cross-communicate between separate H1 links. This localized control completely offloads cyclic macro-cycle management from the central IEC 61131 controller, guaranteeing continuous process execution even during host disconnects.

        The ABB LD800HSE is fully optimized for the ABB Ability™ System 800xA and Freelance DCS environments, enabling complete transparency via System Management and Network Management Agents. Alarms, events, and asset optimization data generated by sub-tier field instruments are systematically aggregated and reported through the ABB LD800HSE directly to system connectivity servers. This ensures that predictive maintenance packages can instantly tap into advanced device diagnostics, reducing plant downtime and enhancing overall asset lifecycle management.  

        Designed for the uncompromising demands of heavy industrial plants, the ABB LD800HSE natively supports redundant physical topologies to protect critical loops from a single point of failure. Two physical ABB LD800HSE units can be coupled together using a dedicated RS-232 serial null-modem cable to synchronize control states and monitor heartbeat status. In the event of a primary hardware failure, the secondary linking device initiates a bumpless switchover, maintaining uninterrupted control signals across the entire process architecture.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        What are the strict session and VCR network capacity limits when configuring the ABB LD800HSE on an HSE subnet?
        The ABB LD800HSE is built to handle complex multi-device field subnets. On the HSE side, the ABB LD800HSE supports a maximum of 64 configured HSE sessions, up to 400 configured HSE Virtual Communication Relationships (VCRs), 32 automatic HSE sessions, and 256 automatic HSE VCRs, giving engineers plenty of bandwidth for high-density instrument mapping.
        How does the ABB LD800HSE manage data republishing and alarm routing across separate H1 channels without controller intervention?
        The ABB LD800HSE includes built-in gateway routing mechanics compliant with the class 42c profile. It supports up to 64 simultaneous H1-to-H1 data republishings natively, meaning data from an instrument on H1 Link 1 can be directly mapped to a device on H1 Link 2 through the ABB LD800HSE without wasting execution cycles on the primary IEC 61131 control system. Alarms and events are passed transparently straight up to the System 800xA Connectivity Servers.
        Can the firmware of the ABB LD800HSE be upgraded remotely, and how is its baseline IP address initially assigned?
        Yes, the ABB LD800HSE supports remote firmware updates via network downloads, simplifying maintenance over long lifecycles. For commissioning, the ABB LD800HSE features an integrated web server that allows field engineers to configure, modify, and lock the IP address and subnet masks using a basic web browser on a laptop connected to the RJ45 port.
        How should the VCR types be budgeted per individual H1 channel on the ABB LD800HSE?
        Each of the four individual H1 channels on the ABB LD800HSE supports a maximum limit of 128 total VCR connections. This allocation can include up to 20 Source + Sink VCRs, up to 40 Client + Server VCRs, and up to 100 Publisher + Subscriber VCRs. Note that because the ABB LD800HSE hardware module does not generate intrinsic fieldbus alarms itself, there is no practical engineering requirement to allocate Source VCRs to the module.
        What are the hazardous location explosion-proof certifications and environmental compliance standards met by the ABB LD800HSE EX variant?
        The ABB LD800HSE EX is thoroughly certified for decentralized installation in Zone 2 / Division 2 explosive hazardous atmospheres. Its safety compliance ratings include cULus Class I, Division 2 (Groups A, B, C, D), IECEx Ex nA IIC T4 Gc, and ATEX II 3G Ex nA IIC T4 Gc. It also carries standard CE compliance certifications for the EMC Directive 2004/108/EC and Low Voltage Directive 2006/95/EC.
        What are the physical mounting constraints and clearance considerations for installing the ABB LD800HSE inside an outdoor cabinet?
        The ABB LD800HSE is designed for high-density spacing, featuring a 47 mm wide IP20 housing that snaps onto a standard 35 mm DIN rail. It has a rated operating range of 0°C to +55°C, but system integrators must ensure adequate ventilation. Installing the ABB LD800HSE in a non-vertical orientation or within tight, unventilated enclosures will restrict natural air convection, requiring a derating of the upper ambient temperature limit.
