Moore Industries Adds EtherNet/IP to Bridge HART Instrumentation and Modern Control Systems

Key Takeaways

• EtherNet/IP added to Moore HES bridges HART to Rockwell PLCs
• Supports up to 64 HART devices via four‑channel HES model
• Enables implicit I/O messaging, reducing network overhead vs MODBUS/TCP
• Retrofit‑friendly DIN‑rail design simplifies integration without rewiring
• Optional EtherNet/IP can be ordered alongside existing MODBUS/TCP

Pulse Analysis

Industrial automation is increasingly driven by the need to extract real‑time intelligence from legacy field devices. Moore Industries’ HART‑Enabled Smart (HES) gateway has long provided MODBUS/TCP and HART‑IP interfaces, but a sizable portion of manufacturers rely on Rockwell Automation’s EtherNet/IP ecosystem. By embedding native EtherNet/IP support, the HES now appears as a standard adapter in a PLC’s I/O tree, allowing process variables and diagnostics from up to 64 HART instruments to flow directly into Rockwell Logix controllers. This eliminates the extra protocol cards or middleware that previously hampered seamless data integration.

The technical shift from a request‑response MODBUS model to EtherNet/IP’s producer‑consumer architecture brings tangible performance gains. Implicit I/O connections publish HART data at configurable cyclic rates, reducing polling traffic and improving determinism for control‑critical loops. Engineers can map assembly objects to PLC tags without manual register translation, streamlining alarm management and predictive‑maintenance algorithms. Configuration remains straightforward thanks to Moore’s IP address utility and familiar FDT containers, meaning teams can leverage existing Studio 5000 or RSLogix tools rather than learning a new gateway interface.

From a market perspective, the addition opens Moore’s HES to the estimated 40 million HART field devices already installed across oil & gas, chemicals, and discrete manufacturing. Plants that have invested heavily in Rockwell PLCs can now retrofit these legacy loops without costly rewiring or instrument replacement, accelerating IIoT adoption and data‑driven optimization. Competitors offering separate protocol converters may see pressure as Moore bundles connectivity into a single, DIN‑rail‑mountable module. The move positions the company as a bridge between traditional analog instrumentation and the digital analytics platforms that dominate today’s smart factory strategies.
