Features:
- 96 MHz processor.
- 1 MB fast user memory.
- Floating-point calculations.
96 MHz processor establishes the principal capability of
IC697CGR935 within its Series 90-70 function.
The relationship between 1 MB fast user memory and floating-point calculations determines how the module fits the surrounding rack, network, or field circuit.
During service, redundancy synchronization must remain consistent with the saved application and the installed hardware.

Controller roles supported by IC697CGR935
- Paired operation: The 96 MHz CPU is used in enhanced hot-standby redundancy systems.
- Memory capacity: One megabyte of battery-backed fast CMOS RAM holds the larger control application and data set.
- Program choice: The primary and secondary PLCs may carry matching or deliberately different programs.
- Shared field system: Both controllers coordinate access to common IC660/IC661 Genius I/O.
Keeping the backup controller current
- Backup data: The amount of application data exchanged between CPUs is configurable.
- CPU alignment: Synchronization maintains an eligible backup before a transfer of control.
- Scan effect: Redundancy communication adds a defined extension to the normal controller scan.
- Recovery path: A repaired unit can rejoin the pair through the supported online repair procedure.
Processing and I/O scale
- Processor: The controller uses a 96 MHz 80486DX4 with floating-point capability.
- Discrete points: As many as 12K inputs and 12K outputs are supported.
- Analog references: The CPU accommodates up to 8K analog inputs and 8K analog outputs.
- Interface ports: Three SNP serial ports provide separate factory-test and programming connections.
Recognizing redundancy conditions
- Changeover record: Status information identifies which controller owns the process and why a switch occurred.
- Consistency checks: Parity and checksum tests protect the memory exchanged between the pair.
- Fault isolation: Controller fault tables are reviewed together with redundancy symptom bits.
- Operator action: Program-controlled or manual switching is performed only after the backup state is valid.
