Technical Dossier
The GE Fanuc Series 90-70, identified by the IC697 part number prefix, is one of the most widely deployed programmable logic controller (PLC) platforms in global heavy industry. Since its commercial introduction in the late 1980s, the Series 90-70 has accumulated a substantial installed base across petrochemical refineries, nuclear power facilities, pulp and paper mills, automotive assembly lines, and municipal water treatment infrastructure. Its VMEbus-based backplane architecture, combined with a broad I/O module library, made it the platform of choice for large-scale discrete and process control applications throughout the 1990s and into the 2000s.
The IC697CPX935 is a coprocessor module within this platform, designed to offload computational tasks from the primary CPU and extend the processing capacity of complex control programs. Its continued presence in operating facilities underscores the long service life of the Series 90-70 architecture — and the ongoing demand for verified spare parts to sustain those systems.
GE has formally transitioned the Series 90-70 to end-of-life status, with hardware manufacturing discontinued. Replacement parts are no longer available through standard distribution channels. For facilities that cannot justify a full control system migration — a project that routinely costs between USD 500,000 and several million dollars depending on system scale — sourcing verified spare modules from specialist suppliers is the only operationally viable path.
The Series 90-70 was engineered around the VME (Versa Module Eurocard) bus standard, a 32-bit parallel backplane architecture that provided high-speed data transfer between CPU and I/O modules. This design decision gave the platform exceptional throughput for its era and allowed third-party module integration — a capability that extended its adoption across diverse OEM applications.
Early Generation (IC697 Rev A/B, late 1980s – mid 1990s): Initial releases focused on discrete I/O and basic analog processing. CPU modules such as the IC697CPU731 and IC697CPU771 established the programming model using GE's Logicmaster 90 software environment. Backplane configurations supported up to 9 slots per rack, with multi-rack expansion via the IC697BEM711 bus expansion module.
Mid Generation (IC697 Rev C/D, mid 1990s – early 2000s): This phase introduced enhanced CPU modules (IC697CPU781, IC697CPU788) with expanded memory and faster scan times. Ethernet and Genius bus communication adapters were added to the catalog, enabling integration with SCADA systems and distributed I/O networks. The IC697CMM711 and IC697CMM742 communication modules became standard components in networked installations.
Late Generation / Transition Phase (2000s – 2015): GE introduced the PACSystems RX7i as the architectural successor to the Series 90-70. The RX7i maintained backward compatibility with IC697 I/O modules through a VME-compatible backplane, providing a migration path that preserved existing I/O wiring infrastructure. However, CPU and communication modules are not interchangeable between platforms. Many facilities elected to retain Series 90-70 hardware rather than undertake partial migrations, creating the sustained demand for IC697 spare parts that persists today.
End-of-Life Declaration: GE Fanuc (subsequently Emerson Automation Solutions under the Movicon/PACEdge portfolio) formally discontinued Series 90-70 hardware production. Software support for Logicmaster 90 and early versions of Machine Edition has also been curtailed, creating additional maintenance complexity for facilities running legacy program archives.

Common sourcing scenarios handled by DriveKNMS include: emergency single-unit replacement for unplanned failures; multi-unit reserve procurement for facilities with 3–5 year maintenance horizons; and full rack assembly sourcing for facilities commissioning a parallel backup system prior to a planned migration.
The Series 90-70 backplane uses a VMEbus parallel architecture with direct electrical contact between module edge connectors and the backplane bus. Modules that have been in service for 15–25 years present specific failure modes that require targeted inspection protocols before being offered as replacement parts.
