The display of very short production interruptions makes the OEE analysis unclear and may skew the calculated KPIs. For example, it may be unavoidable that a machine stops for an insignificant period of time because material is not immediately available. It is usually not desirable for such micro-stops to be included in the analysis.
When configuring an OEE dashboard, you define the basis on which a micro-stop is detected:
- Transmitted from the controller via a variable
- Defined in milliseconds as fixed period
The configuration for micro-stops applies to an asset. A micro-stop threshold or a parameter can be defined per asset.
Downtimes detected as micro-stops are filtered out of the analysis and do not influence the calculation of the KPIs.
The dashboard displays how many micro-stops were detected and how long they lasted in total.
If you change the basis for the micro-stop (fixed period) in the OEE configuration, the KPIs are recalculated and updated.
