Solving the Discontinued Hardware Crisis

The Honeywell WEB-600 served as a central web-based controller in WEBS and EBI building management architectures deployed widely across commercial, industrial, and institutional facilities from the early 2000s through the 2010s. Its role — managing HVAC, access, and energy subsystems through a unified IP-based interface — made it deeply embedded in site infrastructure. Honeywell has since discontinued this product line, and no direct OEM replacement exists that preserves existing programming, network topology, and field device wiring without a full re-engineering effort.

Sourcing a verified WEB-600 from DriveKNMS eliminates that risk. The existing system continues operating. Existing programming is preserved. Engineering resources are not diverted. The asset lifecycle is extended — in most cases by five to ten years — at a fraction of the cost of forced migration.

Condition & Reliability Assurance

Discontinued hardware sourced from secondary markets carries inherent risk. DriveKNMS applies a structured five-step inspection protocol to every WEB-600 unit before it is offered for sale:

• Step 1 – Visual and Physical Inspection: Full examination of housing, connectors, and PCB for physical damage, corrosion, or evidence of prior field failure.
• Step 2 – Electrolytic Capacitor Assessment: Aging electrolytic capacitors are the primary failure mode in controller hardware of this generation. Each unit is inspected for capacitor bulging, leakage, and ESR degradation. Units with compromised capacitors are either recapped or rejected.
• Step 3 – Firmware Version Verification: Firmware is confirmed against known stable release versions compatible with WEBS and EBI environments. Units with corrupted or unknown firmware states are not offered for sale.
• Step 4 – Pin and Connector Integrity Check: All I/O connectors, communication ports, and power terminals are inspected for oxidation, pin deformation, and contact resistance. Corroded contacts are treated or the unit is rejected.
• Step 5 – Functional Bench Test: Where test infrastructure permits, units are powered and verified for basic operational response prior to dispatch.

Key Features for System Maintenance

How do I confirm the unit is genuine and not counterfeit?
All units are sourced through documented supply chain channels. Honeywell part markings, date codes, and board revision identifiers are verified during inspection. Customers may request pre-shipment photographs of the specific unit, including board-level detail, prior to purchase confirmation.

How long can a WEB-600 be stored before use?
Properly stored in a dry, temperature-controlled environment (15–25°C, <60% RH), controller modules of this type retain functional integrity for five or more years. DriveKNMS can advise on appropriate storage conditions upon request.
