3.1 Controls & Indicators
- RUN/STOP/LOCK Switch
RUN: Execute program; enable I/O.
STOP: Halt program; disable I/O.
LOCK: Prevent local mode changes (software override possible).
- Memory Protect Keyswitch
ON: Write‑protect program/config data.
OFF: Allow read/write access.
- LED Indicators (7)
PWR: ON = Backplane power OK.
RUN: ON = Program executing; blinking = fault.
FAULT: ON = System error (CPU, memory, I/O).
COM1/2/3: Blinking = Activity on respective ports.
REDUND: ON = Redundancy active; blinking = failover.
- Ports
RS‑232: D‑sub 9 (programming/HMI).
RS‑485: Terminal blocks (Ch2/Ch3).
4. Installation Instructions
4.1 Pre‑Installation
Power Off: Disconnect all rack power before installation.
Unpack & Inspect: Check for physical damage; verify connectors and battery.
Battery Installation: Insert lithium CMOS battery into the onboard slot (maintains RAM data during power loss).
4.2 Rack Mounting
Slot Selection: Install the CPU in Slot 1 of the IC697 rack (primary segment; redundant CPU in Slot 7 for dual‑redundant racks like IC697CHS770D).
Insertion: Align module with rack guides; push firmly until backplane connectors fully seat.
Secure: Tighten front panel screws (torque: 0.8–1.0 N·m).
Grounding: Ensure rack chassis is connected to protective earth (PE).
4.3 Wiring
RS‑232: Connect D‑sub 9 cable to programming PC/HMI.
RS‑485: Wire to terminal blocks (Ch2/Ch3) for fieldbus networks; observe polarity.
Redundancy: Connect CPU redundancy link cable between primary and secondary CPUs (for hot‑standby).
5. Redundant System Configuration
5.1 Redundancy Setup
Dual CPUs: Install two identical IC697CPX928‑FE modules (primary in Slot 1, secondary in Slot 7 of a dual‑redundant rack).
Redundancy Link: Connect dedicated synchronization cable between primary and secondary CPUs.
Configuration Software: Use GE Fanuc programming software to enable hot‑standby mode and set failover parameters.
5.2 Redundancy Operation
Primary Active: Primary CPU controls I/O and executes program; secondary CPU mirrors all data (hot standby).
Failover: On primary failure (CPU, power, or critical I/O), system switches to secondary in <50 ms (no PLC downtime/reset).
Resynchronization: After repair, primary automatically resynchronizes with secondary; redundancy restored.
6. Maintenance & Troubleshooting
6.1 Preventive Maintenance
Battery Replacement: Every 3–5 years (or when low‑battery LED alerts); use GE‑specified lithium battery.
Cleaning: Every 3–6 months, use low‑pressure dry air to remove dust from module, ports, and rack.
Inspection: Check module seating, connector integrity, LED status, and redundancy cable connections.
6.2 Common Troubleshootin
| Symptom | Possible Cause | Solution |
|---|---|---|
| PWR LED OFF | No backplane power; faulty rack/power supply | Check rack power supply; verify module seating |
| RUN LED OFF / FAULT LED ON | Program error; memory fault; I/O overload | Check program logic; verify battery; inspect I/O modules |
| COM LED Not Blinking | No communication; wrong wiring; protocol mismatch | Check cable connections; verify protocol settings |
| REDUND LED OFF | Secondary CPU offline; missing/broken link cable | Verify secondary CPU power; check/replace redundancy cable |
| REDUND LED Blinking | Failover in progress; configuration mismatch | Check primary CPU faults; ensure identical firmware/config on both CPUs |
