Features:
- Controls up to 352 mixed I/O points in a GMR architecture.
- Uses a 16 MHz 32-bit processor for coordinated redundant logic.
- Works with IC660 and IC661 Genius I/O.
Voting logic allows
IC697CPU788 controllers to compare their operating results before a commanded state reaches the shared field system.
The smaller GMR capacity distinguishes this processor from the higher-point CPU 789 and must be preserved when the application is restored.
Battery-backed memory retains the controller program and redundancy data through loss of rack power.

GMR components paired with IC697CPU788
- Controller set: The processor operates as a member of a coordinated redundant CPU group.
- Field network: IC660 and IC661 Genius devices provide the common I/O layer.
- Capacity boundary: The application must remain within the 352-point mixed-I/O limit.
- Memory: The installed 512 KB expansion board must match the saved controller image.
Controller voting around IC697CPU788
- Program alignment: Participating CPUs require compatible control logic and redundancy settings.
- Data exchange: Operating states are shared so each controller votes from the current process condition.
- Output decision: The GMR arrangement resolves differing controller results before field commands are applied.
- Resynchronization: A repaired controller is returned only after its state agrees with the operating group.
Fault isolation for an IC697CPU788 group
- CPU comparison: A disagreement between controllers is separated from an I/O-network fault.
- Genius status: Bus health and affected devices are checked before a processor is removed.
- Memory condition: Parity, retained data, and battery state are reviewed when the application will not recover.
- Acceptance test: Voting and transfer behavior are exercised after the repaired controller rejoins.
Smaller redundant systems using IC697CPU788
- Critical sequencing: Controller voting protects interlocks that cannot depend on one processor result.
- Process units: The 352-point limit suits compact process areas requiring redundant decisions.
- Material transfer: Shared Genius I/O coordinates conveyors and routing equipment across controller faults.
- Utility control: Redundant logic maintains essential auxiliary services while one CPU is isolated.
