Product Role & System Fit
The IC697CGR935 is a central processing unit (CPU) module intended for use in GE Fanuc Series 90-70 programmable logic controller (PLC) racks. Its core purpose is to execute automation logic and coordinate I/O operations while enabling redundant control configurations — a key requirement for systems where continuous uptime is critical.
In a redundant PLC setup, two identical CPUs operate in parallel: a primary and a standby. Both receive power and synchronize their internal state, so if the active unit experiences a fault or drops offline, the secondary takes over control almost instantly (“bumpless transfer”). This capability is vital in environments like power plants or refinery process control where even momentary downtime can lead to safety interlocks or equipment trips.
Within the Series 90-70 architecture, the IC697CGR935 communicates with I/O and specialty modules over the rack’s backplane. It interfaces seamlessly with various I/O types — discrete, analog, and specialty communication modules — giving engineers flexibility in system design. SCADA and higher-level supervisory systems typically connect via serial or network modules that tie into the CPU’s communication ports.
Third-party and legacy tooling support (such as GE’s Logicmaster 90-70 or later Proficy Machine Edition) allow control code to be developed, downloaded, and monitored on this CPU. Though the Series 90 lines are considered legacy platforms today, they remain prevalent in many long-running installations, and components like the IC697CGR935 help preserve continuity in those systems.
This controller’s programming capabilities — including floating-point operations and Boolean logic execution — allow it to manage advanced control algorithms, sequencers, and interlocks across complex I/O networks. Its support for battery-backed memory and fail-safe modes ensures operational stability even during power disruptions.
