GE Fanuc IC697CPU731 – Series 90-70 CPU Module for High-performance PLC Control

• Warranty: 365 days

• Delivery: 1 week for in‑stock items; no more than one month at the latest

• Payment: 50% advance payment, full payment prior to delivery

• Express: FedEx, UPS, DHL

• Series 90‑70 platform – Works with the proven IC697 ecosystem, which many plants still rely on for continuous operation.

• Single‑slot CPU design – Saves rack space; installs in the designated CPU slot of the IC697 rack without special adapters.

• Programmer serial port – Typically provides an RS‑232 SNP/SNPX port for programming and diagnostics with Logicmaster 90‑70 or Proficy Machine Edition.

• Expandable communications – Add Ethernet TCP/IP, Genius, or other networks using standard IC697 communications modules, keeping the CPU core unchanged.

• Battery‑backed memory – Uses IC697 memory modules (IC697MEM7xx) for user program and data retention; ideal for brownouts or planned shutdowns.

• Industrial operating range – Designed for cabinet‑mounted use in typical factory environments where 0–60°C is common.

• Long‑term serviceability – Spare parts and accessories remain available in many markets; makes life easier for MRO teams.

From my experience, the IC697CPU731 is typically chosen for lines that must stay compatible with existing 90‑70 infrastructure while keeping downtime minimal:

• Process industries (chemicals, batch, utilities) where stable scan cycles and proven logic are valued

• Discrete manufacturing and automotive cells using established IC697 I/O and Genius‑based remote I/O

• Power, water/wastewater plants with legacy redundancy or long validated configurations

• Material handling, steel, and heavy industry where ruggedized cabinet PLCs are standard

• Reliability – 90‑70 hardware has a reputation for long service life; many units run for decades with routine maintenance.

• Compatibility – Reuses your existing IC697 racks, I/O, and many communications modules; no need to redesign the whole panel.

• Cost control – A direct CPU swap typically reduces engineering hours, revalidation time, and training compared to full platform migrations.

• Supportability – Documentation, spare parts, and service know‑how are widely available; technicians are usually familiar with the toolchain.

• Cabinet & rack – Install in an IC697 rack within a ventilated, dry control cabinet. Maintain clearance for airflow and cable bend radius.

• Power & grounding – Use a properly sized IC697 power supply. Ensure protective earth and signal grounding are clean to avoid comms noise.

• Wiring – Use shielded cables for the programmer port and network modules; segregate low‑level signals from high‑voltage power wiring.

• Environment – Keep within 0–60 °C and non‑condensing humidity. Avoid corrosive atmospheres unless cabinet is rated accordingly.

• Memory & battery – Check the memory module part and battery status during PMs. Battery packs are usually replaced every 3–5 years.

• Firmware & backups – Verify CPU and comms module firmware levels are compatible. Keep off‑line backups of the user program and hardware configuration.

• Manufacturer quality system: ISO 9001 (typical for GE Fanuc manufacturing)

• Product safety approvals: UL/cUL and CE (typical for Series 90‑70)

• RoHS: many original units pre‑date RoHS; compliance may vary by vintage and region

• Seller warranty: 365 days
