Glossary
Glossary of reliability and industrial data.
The terms used across the site and the product, with the meaning they have at Ordanis. When a term has a guide, the link leads to the full explanation.
- MTBF (mean time between failures)
- Running time in the period divided by the number of failures (mtbf.v1). Only published with enough failures and data coverage. Learn more: Industrial reliability →
- MTTR (mean time to repair)
- Average time from failure start until the asset is back to RUNNING, counting only repairs with a reliable start and end (mttr.v1). Learn more: Industrial reliability →
- Availability
- In Reliability, running time inside the planned schedule over planned time minus unknown-state time (availability.v1). Different from the OEE A factor. Learn more: Industrial reliability →
- OEE (Overall Equipment Effectiveness)
- Availability × performance × quality. In Ordanis Factory it follows the factory.oee.v1 method, with the six big losses. Learn more: OEE →
- Six big losses
- Breakdowns; setup and adjustments; idling and minor stops; reduced speed; defects; startup losses. Ordanis also shows unclassified stops separately. Learn more: OEE →
- Microstop
- Short unplanned stop between a minimum duration (below is noise) and a maximum (above is unplanned downtime), defined per scope and versioned. Learn more: Downtime management →
- Unplanned downtime
- An off-plan stop lasting at least the microstop maximum. A stop is not automatically a failure. Learn more: Downtime management →
- Failure
- An event that the failure definition agreed with maintenance treats as loss of function. It is what counts for MTBF. Learn more: Industrial reliability →
- Baseline
- Normal behaviour of a signal or metric over a reference period, with method and confidence recorded. Pilot targets are only set after it. Learn more: Predictive maintenance →
- Predictive maintenance
- Acting before a failure based on the asset's condition. At Ordanis today this means deviation detection with auditable rules and baselines. Learn more: Predictive maintenance →
- Detection lead time
- Time between the first related detection and the reference event (for example, the failure). Learn more: Predictive maintenance →
- OPC UA
- Open industrial communication standard. The Ordanis Edge is a read-only OPC UA client: it reads values and never writes to nodes. Learn more: Asset monitoring →
- Ordanis Edge
- Software on a commercial industrial PC in the plant that reads data and sends it to the platform over an outbound-only connection, with a local buffer. Learn more: Asset monitoring →
- Tag
- A raw data point from a PLC or OPC UA server. It only becomes a useful signal once mapped to an asset. Learn more: Asset monitoring →
- CMMS
- Computerized maintenance management system (work orders, plans, history). Ordanis reads the customer's CMMS; it does not replace it. Learn more: Platform →
- INSUFFICIENT_DATA
- Status of a calculation without enough data: no number is published and the reason is shown with it. Learn more: Industrial reliability →
