Solving the Discontinued Hardware Crisis

The GE Series 90-70 platform was the backbone of process automation for over two decades. Its VME-based architecture, while robust, is no longer supported under active GE/Emerson service contracts. The IC697CMM712 handles all serial communications between the CPU rack and field devices — including SCADA hosts, operator interfaces, and third-party instrumentation using SNP, SNP-X, and Modbus RTU protocols. There is no direct modern equivalent that installs into the existing rack without hardware and software re-engineering.

Facilities operating Series 90-70 systems face a binary choice: fund a full migration project — with its associated engineering hours, new hardware procurement, software rewrite, FAT/SAT testing, and production freeze — or maintain the existing system with verified spare modules. For plants where the control system governs continuous processes, the migration path is rarely a one-quarter decision. The IC697CMM712 is the communications backbone of that system. Its failure without a spare on hand converts a maintenance event into a capital project.

Facilities that have extended Series 90-70 asset life by 5 to 10 years through strategic spare parts management consistently report the same approach: identify the three to five modules with no modern drop-in equivalent, secure RFQ-reviewed sourcing status of each, and establish a documented inspection cycle. The IC697CMM712 is on that list for any site running serial-connected field devices.

Condition & Reliability Assurance

DriveKNMS applies a 5-step quality process to all obsolete modules before dispatch review:

• Step 1 – Visual Inspection: Full board inspection for physical damage, corrosion on edge connectors and pin headers, and evidence of prior field repair or rework.
• Step 2 – Electrolytic Capacitor Assessment: Targeted inspection of electrolytic capacitors for bulging, leakage, or ESR drift — the primary failure mode in modules of this age.
• Step 3 – Firmware Version Verification: Where accessible, firmware revision is documented and cross-referenced against GE Fanuc release notes to confirm compatibility with target rack configurations.
• Step 4 – Functional Bench Test: Module is powered and communications ports are exercised under controlled conditions prior to packaging.
• Step 5 – Anti-Static Packaging & Documentation: Shipped in ESD-safe packaging with inspection record. Lot traceability maintained in DriveKNMS records.

Key Features for System Maintenance

• Drop-in replacement: The IC697CMM712 installs directly into any Series 90-70 VME rack slot without rack modification.
• No reprogramming required: Configuration is stored in the CPU — module replacement does not require PLC program changes in standard deployments.
• Avoids engineering reconstruction costs: Replacing this module preserves the existing control architecture, eliminating the need for costly system re-engineering, new HMI integration, or network reconfiguration.
• Maintains SCADA and field device connectivity: Restores serial communications to all connected field devices and host systems without protocol conversion or gateway hardware.
• Long-term sparing strategy: Given the discontinuation status, facilities managing multiple Series 90-70 racks are advised to secure more than one unit as insurance against future sourcing failure.

Q: Can you verify compatibility with my specific rack configuration before purchase?
A: Yes. Provide your rack model, CPU part number, and current firmware revision. DriveKNMS will confirm compatibility before invoicing.
