Features:
- 64 MHz 80486DX2 processor with 32-bit floating-point calculations and 0.4 μs Boolean execution.
- 1 MB of battery-backed memory, with up to 512 KB available for application logic and data.
- Supports IC66 Genius Modular Redundancy, voted I/O configurations, and critical TMR control applications.
The GE Fanuc IC697CPM790-DC is a single-slot Series 90-70 CPU designed for IC66 Genius Modular Redundancy systems. It executes control logic, I/O scanning, system diagnostics, floating-point calculations, and communication functions.
The module is intended for emergency shutdown, fire and gas detection, process protection, and other critical applications. It supports simplex and voted I/O architectures using redundant PLCs, Genius buses, and field signals.
The IC697CPM790-DC supports IC660/IC661 Genius I/O and compatible IC697 modules through the VME C.1 backplane. Software configuration, status LEDs, password protection, memory protection, and optional Ethernet connectivity simplify operation and maintenance.
The IC697CPM790-DC belongs to the legacy Series 90-70 platform, which the manufacturer recommends modernizing to PACSystems RX3i.

- Emergency shutdown systems requiring redundant PLCs, voted field signals, automatic testing, and dependable fail-safe control.
- Fire and gas detection systems that monitor critical inputs and coordinate reliable alarm, trip, and protection functions.
- Critical process-control applications requiring fault tolerance, redundant Genius buses, continuous diagnostics, and high system availability.
- The IC697CPM790-DC is programmed and configured through compatible MS-DOS or Windows software using an SNP serial connection or optional Ethernet interface.
- All hardware settings are software-configured without DIP switches or jumpers, and configurable memory can be allocated between program and data requirements.
- TMR operation requires a Standalone C program containing the appropriate redundancy control and automatic-test routines.
- The 64 MHz 80486DX2 processor supports floating-point calculations and executes Boolean functions in approximately 0.4 microseconds.
- Its 1 MB battery-backed memory provides up to 512 KB for application logic and data while retaining information during power loss.
- The IC697CPM790-DC supports extensive simplex and voted I/O capacities for efficient operation in large redundant control systems.
- Four front-panel LEDs display module health, CPU operating state, output status, and memory-protection status.
- The CPU checks the programmed and installed rack configuration at startup and during operation, reporting mismatches through its alarm processor.
- Power-up diagnostics detect low-battery conditions, with the MODULE OK LED indicating when reliable memory backup is unavailable.
