Identification Overview

Alstom part number: M0009483
Original OEM part number: IC697CPX928
Platform: GE Fanuc Series 90‑70 PLC, deployed under Alstom power‑generation control systems

M0009483 is the Alstom drawing reference for the IC697CPX928 high‑performance CPU, widely integrated within Alstom turbine and boiler control solutions. This single‑slot VME‑form‑factor CPU executes real‑time process control logic, floating‑point arithmetic, and manages local and remote Genius I/O networks. Since the Series 90‑70 platform is end‑of‑life, M0009483 / IC697CPX928 serves as a mission‑critical spare for power‑plant brown‑field sites to avoid large‑scale control‑system migration projects.

 

Core Hardware Specifications

• Processor: 96 MHz 80486DX4 32‑bit microprocessor, floating‑point math support
• Memory: 6 MB battery‑backed CMOS RAM; 256 KB non‑volatile flash memory for firmware and user program storage
• Max I/O capacity: up to 12 000 mixed discrete / 8 000 analog I/O points
• Serial interfaces: 1 × RS‑232, 2 × RS‑485 (one optically‑isolated); supports SNP and Modbus RTU protocols
• Execution speed: 0.4 μs per boolean instruction
• Power draw: approx 3.1 A, powered from Series 90‑70 rack backplane
• Operating temperature: 0 °C ~ +50 °C, indoor rack‑mount non‑condensing environment
• Front‑panel multi‑LED array for run, fault, diagnostic status indication

Functional Capabilities & System Integration

The Alstom‑referenced M0009483 (IC697CPX928) functions as the central control engine for large‑scale PLC installations. It runs complex control algorithms including PID loops, turbine sequencing, interlock logic and mathematical calculations via native floating‑point processing. The module communicates with local I/O modules over the 90‑70 backplane bus and connects to distributed Genius remote I/O stations. Optional Ethernet coprocessor modules can be added to link the CPU to SCADA and plant supervisory networks. Hot‑standby redundant CPU configurations are supported to enhance availability for critical power‑generation applications. Programming is performed using Logic Developer or VersaPro software over its serial communication ports.

 

Typical Field Deployment Scenarios

This CPU is most frequently found within Alstom and GE power‑plant control cabinets, used for steam‑turbine auxiliary control, boiler sequence control, balance‑of‑plant equipment interlock and process regulation. Sites maintain spare M0009483 / IC697CPX928 units to replace failed CPUs caused by battery exhaustion, flash‑media degradation, backplane‑connector wear or component ageing. It is also selected for brown‑field upgrade projects to boost processing capacity within existing Series 90‑70 rack infrastructure without full rack replacement.

Important Procurement & Installation Notes

• When sourcing, cross‑check both Alstom M0009483 and original IC697CPX928 part markings; M0009483 is Alstom’s internal reference number for this GE‑manufactured CPU, not a separate hardware redesign.
• Only compatible with GE Fanuc Series 90‑70 chassis; cannot be interchanged with Series 90‑30 or RX3i CPU families.
• Inspect and replace the CPU backup battery on replacement units to prevent loss of retentive memory during power‑cycle events.
• Follow ESD anti‑static handling procedures for the plug‑in CPU board; perform lockout‑tagout and de‑energize rack power before card insertion or removal.
• After installation, download validated user project, execute full CPU self‑diagnostic check, verify backplane and Genius I/O communication, and validate interlock‑logic execution.

Closing Summary

Alstom M0009483 (IC697CPX928) remains a vital legacy CPU spare for power‑generation plants operating Series 90‑70 based control systems. Its high‑speed floating‑point computing, large‑I/O handling capability and multi‑port communication support extend service life for critical turbine‑and‑boiler automation assets.
