Working Principle Primary and backup processors synchronize process data, control state, and I/O images in real time over the high-speed redundant bus. Normally the primary executes control while the backup mirrors data without output. On primary failure the backup takes over within milliseconds without output interruption. LEDs indicate current primary/backup state and bus link.
Installation Requirements
- Insert redundancy slot with power off, pair primary and backup
- Connect primary/backup cards with dedicated redundant bus cable
- Rack grounding
- Temperature 0 °C to +60 °C
- Configure redundancy pair in TPS system software after power-up
- Primary and backup card models must match
Precautions
- Do not hot-swap during online operation
- Primary and backup card versions must match
- Redundant bus cable is dedicated, do not substitute
- Periodically perform switchover tests
- Store spares in anti-static moisture-proof packaging
- Wear ESD wrist strap
