Product Introduction & Supply Chain Strategy
The ABB CI631 is a communication interface module for Advant Fieldbus 100 networks in ABB Advant Controller 160 (AC 160) systems. It connects processors to remote I/O via twisted pair cabling, supervising cyclic Data Set updates to prevent stale process data in power plants and industrial DCS.library.
New Surplus stocking counters EOL stock-outs for discontinued AF100 infrastructure, cutting TCO versus OEM by avoiding refurbished comms failures like dropped Data Sets causing control loops to freeze. Buffer min/max 1/2 units with 1-year warranty at 40-50% below list.
Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
Lock out/tag out controller rack. ESD strap required. Photo existing twisted pair wiring (A/B/GND), terminator positions, node addresses. Verify 24 V DC supply buffer.
Stage 2: Removal
Disconnect fieldbus cables from terminals—no pulling on wires. Release module latch from AC 160 backplane. Extract straight to protect pins.
Stage 3: Installation (Clone & Seat)
Match wiring per photos to screw terminals (A+, B-, GND shield). Seat into backplane slot; secure latch. Confirm terminator at segment ends.
Stage 4: Power-On & Testing
Power up controller; check module LEDs (Power/Comm OK). Ping AF100 network via diagnostic tool; verify Data Set refresh—no supervision faults.
Firmware/Software Versions & Upgrade Notes
No module firmware; configuration via AC 160 engineering tool (Advant Fieldbus 100 Configurator V2.x). Compatible with processor modules PM860/863.
Version mismatches drop Data Sets; document network config pre-swap. Test cyclic updates at 500 ms intervals post-install

Frequently Asked Questions (FAQ)
Is this verified New Surplus?
Yes—factory sealed with original backplane pins intact, full comms QC test. Avoids used modules with oxidized bus contacts dropping packets.
Pricing between OEM and refurb?
Global last-time-buy at 40-50% off list price; ensures Data Set integrity vs. refurbished timeouts costing hours of troubleshooting.
EOL for CI631 AF100 module?
Discontinued for legacy AC 160; stock 1-2 via vendor consolidation as slow-mover insurance.
Hot-swap possible?
No—controller power-off required to prevent bus collisions. Live swap corrupts fieldbus traffic.
Config retained after replacement?
Network params in processor module; CI631 is hardware interface only. Backup fieldbus database first.
