Downtime Reasons

Navigation: OEE → OEE Configuration → Downtime Reasons

Description:

• The Downtime Reasons tab defines a hierarchical tree of Downtime Reasons for a location. Reasons categorize why a location was down, and are assigned to downtime events either automatically (via the Downtime Reason Expression) or manually on the Downtime Entry page. The hierarchy lets you roll up and drill down on downtime causes in analysis (see the Downtime Pareto).
• See the OEE Downtime Reason data model for the underlying structure.

The reason tree is shown on the left; selecting a reason loads its details in the editor on the right.
