ABB UBC717AE01 (HIEE300927R0101) – System Bus/Communication Controller for Advant OCS Racks

The ABB UBC717AE01, part number HIEE300927R0101, is a rack plug‑in controller module used in ABB Advant OCS installations. From my experience, it’s typically applied as a system bus or communication coordination board inside the controller rack, helping the CPU and I/O stations talk reliably over the internal backplane and plant network segments. If you’re maintaining legacy Advant lines, this module seems to be one of those pieces that quietly keeps the whole system synchronized.

Order Placement Process and Guarantees

Key Features

• Advant OCS rack integration – Designed as a plug‑in board for ABB Advant controller frames, minimizing retrofit effort.
• Reliable system-bus handling – Manages deterministic communication between CPU and I/O, which in many cases prevents sporadic rack faults.
• Backplane-powered – No separate field wiring for power; simplifies cabinet layout and keeps wiring tidy.
• No direct field I/O – The module focuses on internal/system communications, reducing signal noise and front-end complexity.
• Service-friendly replacement – Typically swap-in/align and re-seat; downtime can be kept short with a prepared spare.
• Lifecycle support – Commonly stocked as a high-demand spare for existing Advant plants still running long service cycles.

Technical Specifications

Application Fields

Plants running ABB Advant OCS still rely on these modules for dependable controller-to-I/O communication. You might notice that many operators keep at least one spare on hand to shorten MTTR.

• Power generation (boiler/turbine auxiliaries, balance-of-plant control)
• Oil & gas (compressor stations, utility systems, process units)
• Pulp & paper (stock prep, machine auxiliaries, recovery boiler support)
• Chemicals & petrochem (unit interlocks, utilities, offsites)
• Metals, mining, and cement (material handling, kiln/rolling auxiliaries)

Advantages & Value

• Reliability in legacy fleets – Stable operation reduces nuisance trips and helps maintain predictable scan cycles.
• Compatibility – Matches Advant rack mechanics and electrical specs, so you avoid risky retrofit wiring.
• Cost control – Extends system life without a full DCS migration; typically the fastest way to recover a rack with bus errors.
• Support – Pre‑shipment testing and a 365‑day warranty lower your replacement risk.

Installation & Maintenance

Quality & Certifications

• CE conformity for industrial environments (typical for ABB Advant system components)
• Manufacturer quality system to ISO 9001
• UL/CSA use in many cabinets, dependent on system build
• RoHS applicability varies with production year; many legacy spares are exempt under industrial categories

Supporting Components (commonly paired)

If you’re refreshing an Advant rack, teams typically check companion parts at the same time. A few related items customers often ask for:

• UFC-series controller module – Main CPU board for Advant OCS racks; pairs with UBC717AE01 for stable rack communications.
• UDI-series digital input modules – Field DI termination; the UBC ensures the backplane messaging reaches these I/O cards consistently.
• UAO/UAI-series analog I/O modules – Analog in/out modules used on the same rack; often inspected and cleaned when the bus controller is replaced.
• Advant rack power supply – Verifying backplane 5 V DC stability is a good preventive step when bus faults appear intermittently.

If you need a tested UBC717AE01 (HIEE300927R0101) quickly or want help validating compatibility against your exact Advant rack type, share the controller and rack IDs. One thing I appreciate is how straightforward the swap can be when the cabinet is kept clean and the backplane voltage is solid.
