Product Details And Specifications

HIPROM 1788HP-EN2PA Linking Device – Obsolete ControlNet/PROFIBUS Spare Part

DriveKNMS holds RFQ-reviewed sourcing status of the 1788HP-EN2PA. For plant managers and maintenance engineers operating legacy Rockwell or HIPROM-integrated systems, this is not a commodity purchase. It is an asset protection decision.

RFQ support for obsolete parts: Send the model number, required quantity and destination so DriveKNMS can confirm sourcing options before quotation.

Technical Specifications

Note: Electrical parameters not independently verified. Specifications above are based on product family documentation. Do not rely on unconfirmed values for safety-critical applications.

Solving the Discontinued Hardware Crisis

The 1788HP-EN2PA was designed to bridge two fieldbus worlds that rarely coexist in modern installations: ControlNet, a deterministic, time-division-multiplexed network favored in Rockwell-heavy process plants, and PROFIBUS DP, the dominant fieldbus in European and Asian manufacturing automation. Facilities that built their control architecture around this combination in the late 1990s and 2000s now face a structural problem: neither HIPROM nor Rockwell offers a direct, drop-in successor for this specific gateway function.

Facilities running Rockwell ControlLogix or PLC-5 systems with PROFIBUS DP field devices — drives, valve positioners, remote I/O — are the primary users of this module. If your plant falls into this category and you have not yet secured a spare, the risk exposure is real and quantifiable.

Condition & Reliability Assurance

Sourcing obsolete industrial hardware carries inherent risk. DriveKNMS applies a structured 5-step inspection protocol to every 1788HP-EN2PA unit before it leaves our facility:

• Step 1 – Visual and Physical Inspection: Full examination of housing integrity, connector pins, and PCB surface. Units with physical damage, corrosion, or pin deformation are rejected at intake.
• Step 2 – Electrolytic Capacitor Assessment: Aging electrolytic capacitors are the primary failure mode in hardware of this vintage. Each unit is inspected for capacitor bulging, leakage, or ESR deviation. Units with suspect capacitors are flagged and not sold as-is.
• Step 3 – Firmware Version Verification: Where accessible, firmware revision is documented and cross-referenced against known compatibility requirements for the target ControlNet and PROFIBUS DP environments.
• Step 4 – Pin and Connector Integrity Check: BNC and PROFIBUS DB9 connectors are inspected for oxidation, bent pins, and mechanical wear. Contact surfaces are cleaned where required.
• Step 5 – Functional Power-On Test: Units are powered and observed for normal initialization behavior. Communication handshake testing is performed where test infrastructure permits.

Units are shipped in anti-static packaging with desiccant. Condition grade (New, Refurbished-Grade A, or Tested-Used) is disclosed on the invoice.

Key Features for System Maintenance

Q: How do I know the unit is genuine and not counterfeit?
A: All units are sourced through documented industrial surplus and decommissioning channels. We do not source from unverified secondary markets. Traceability documentation is available on request.
