- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What is the primary function of the Log Writer in manufacturing systems?
**A**: The Log Writer is a software component that reliably writes log data from manufacturing equipment and processes to designated storage destinations, ensuring traceability and system monitoring.

### Q: How does the Write Buffer improve logging performance in electronic manufacturing?
**A**: The Write Buffer temporarily stores log data before writing to storage, preventing system slowdowns during high-volume production runs and maintaining real-time manufacturing operations.

### Q: What error handling features does the Log Writer provide for optical product manufacturing?
**A**: The Error Handler component manages storage failures, data corruption, and system interruptions while maintaining log integrity and providing alerts for critical manufacturing process issues.
