Working Principle Primary processor and backup processor exchange full process data, control algorithm state and I/O image via this redundancy module. Primary processor executes real-time control while backup keeps mirroring all data. When primary processor encounters hardware fault, the module triggers rapid switchover, backup takes over control without interruption of output signal. LEDs indicate operation role and bus communication health.
Installation Requirements
- Insert into TPS rack redundancy slot under power off condition
- Use dedicated redundant bus cable to pair primary and backup modules
- Complete rack protective grounding
- Operating ambient temperature maintained at 0 °C to +60 °C
- Configure redundancy pair in TPS system software after power on
- The paired two modules must have matching firmware version
Precautions
- Hot swap is forbidden during online running
- Firmware version must be consistent for paired modules
- Only use dedicated redundant bus cable, substitute cable is prohibited
- Execute manual switchover test periodically
- Store spare modules in anti-static and moisture-proof packaging
- Wear ESD wrist strap during handling and replacement
