Prerequisites

To enable OEE calculations for machines and lines, it is required to collect OEE typical data from the devices. MindSphere OEE Hub does not require special devices to collect the data from the machines and lines. The only mandatory condition is that the data is stored in the MindSphere timeseries database and structured properly.

Typically, when setting up a machine in MindSphere, you divide the data structure of an asset into multiple aspects. However, it is recommended to create a single aspect in a machine or line asset, that stores all OEE Hub relevant information since it makes the configuration of machines and lines in OEE Hub easier.

In general, OEE Hub is relying on the data points as described in the following table:

Variable Common Datatype Mandatory for OEE calculation Comment
Status STRING, INT Mandatory Status is necessary to enable Availability calculations
Product Code STRING, INT Mandatory Product code is necessary to enable Performance calculations
Order ID STRING, INT Mandatory Enables the Order ID filter capabilities
Good Parts LONG Mandatory - Two out of three must always be available. The third variable can be calculated through the other two.
- Two out of three are necessary to enable Quality calculations
- Can be either difference counter or incremental counter
Bad Parts LONG Mandatory - Two out of three must always be available. The third variable can be calculated through the other two.
- Two out of three are necessary to enable Quality calculations
- Can be either difference counter or incremental counter
Total Parts LONG LONG - Two out of three must always be available. The third variable can be calculated through the other two.
- Two out of three are necessary to enable Quality calculations
- Can be either difference counter or incremental counter
