Features:
- Supports as many as 12K discrete inputs and outputs in any mix.
- Coordinates common IC660 and IC661 Genius I/O.
- Uses redundant controller voting for critical output decisions.
Large I/O capacity lets
IC697CPU789 manage a wider distributed control area than the CPU 788 while retaining the same GMR operating principle.
Each participating processor works from synchronized process information so one inconsistent result can be identified before it controls the field.
Retained expansion memory preserves the application and controller state needed for recovery following rack power loss.

System scale and hardware matched to IC697CPU789
- GMR role: The processor belongs in a coordinated redundant controller group.
- I/O scale: The configured system may contain as many as 12K mixed points.
- Genius devices: IC660 and IC661 products form the distributed field layer.
- Expansion memory: The 512 KB board must be present and initialized for the saved application.
Decision handling in an IC697CPU789 controller group
- State sharing: Controllers exchange the process information needed for equivalent logic execution.
- Result comparison: Voting distinguishes a single inconsistent processor result from the group decision.
- Controller recovery: A repaired unit is synchronized before it can influence commanded outputs.
- Service continuity: Healthy members retain control while a failed processor is isolated.
Troubleshooting a large IC697CPU789 installation
- Scope first: Determine whether the symptom follows one CPU, the Genius network, or a shared field device.
- Fault history: Compare controller fault tables and redundancy status at the same event time.
- Capacity check: Confirm that configured I/O and memory use remain inside the CPU 789 limits.
- Return check: Test synchronization, voting, and field updates after the repaired unit rejoins.
Large-scale duties suited to IC697CPU789
- Plantwide sequencing: The 12K-point capacity supports extensive coordinated interlocks.
- Distributed processes: Genius networks carry field information across broad production areas.
- Material networks: Redundant decisions maintain routing and transfer operations through a controller fault.
- Critical utilities: Multiple CPUs protect essential services from a single processor failure.
