Running OEE Calculations
To start the OEE calculation, select the OEE Equipment Monitor in the ISA-95 Equipment Model and go to the Common section of the properties. Set Processing Mode from 'Configuration' to 'Production'. Then click Apply.
When starting for the first time, the monitor creates a new branch (called 'OEE') in the ISA-95 Equipment Model, underneath its parent object, i.e. the asset which it is monitoring.
The 'OEE' folder contains a number of output objects like a table for logging all production runs and one for logging all the equipment stops on this asset , as well as the OEE related indices for the latest finished production cycle. For a brief overview over these objects see OEE Output Objects
|When the OEE Equipment Monitor is running, the Object State Indicators of the OEE Indices can turn red. In a production environment this means that unusual input values occurred, leading to unexpected numbers for the indices based on this input value. In a simulated environment, using the OEE Simulator Script, such unusual values may occur quite often, depending on the script configuration. As long as the indicators don’t stay red but eventually return to green, the simulation is running correctly.
|The OEE index objects always hold the data for the most recently completed production cycle. To archive this information the Archive Options for the respective index object(s) need to be configured.
