GE Fanuc IC698 Series Technical Notes

The GE Fanuc Series 90-70 (IC698 platform) is a rack-based programmable logic controller system deployed extensively across global heavy industry, including petrochemical refineries, nuclear power generation facilities, offshore platforms, and continuous-process chemical plants. First introduced in the late 1980s and expanded through the 1990s and early 2000s, the IC698 backplane architecture supports high-density I/O configurations and deterministic scan-cycle execution that remain operational in thousands of installed base sites worldwide. The platform's longevity in safety-instrumented and process-critical environments has created sustained demand for spare parts, replacement CPUs, and legacy I/O modules — particularly as OEM support has transitioned to lifecycle management status.
