Behind this dataset
Same schema. As many rows as you need.
These 121 rows came out of a blueprint — 15 columns with generation rules behind each one. Open it in Data Factory to retune a column, add your own, wire in foreign keys, and run it at the size you actually need.
Rules it was built with
- Each row represents a unique device error event
- Event timestamps must reflect operational hours
- Include device type, error code, severity, and location
- Link error events to manufacturing process stages
- Only devices active on the shop floor are included
