Adding OEE Configuration Objects

A number of OEE related configurations are not asset specific but apply to multiple equipments, areas or even plants. Therefore these configurations are centralized in objects of types which are dedicated to different configuration topics.

The OEE Equipment Monitor can be pointed at the Configuration Objects which it should take into account in its Configuration Options property compound. For all the Configuration Object categories, which do not have an explicit reference to a specific Configuration Object configured in the OEE Equipment Monitor’s Configuration Options property compound, the Monitor will traverse the ISA-95 Equipment Model hierarchy upwards in search for such a Configuration Object and use the first one it can find.

Traversing the ISA-95 Model hierarchy in search for Configuration Objects may affect performance and should only be used to find Configuration Objects which are located in close proximity. Configuration Objects which are further away from the OEE Equipment Monitor should be configured explicitly. If no Configuration Object of this type is to be used, the corresponding Configuration Object Source property should be set to '/' to prevent the search.

The Configuration Object Categories

To create the connection between Sites in the ISA-95 Model and Timezone Availability Tracker objects in the I/O Model, which is mandatory for several of the following Configuration Objects, the TPM Site configuration is used.

Work shifts, including their respective local start and end times and their applicability with respect to certain times of the year, are configured using TPM Shift Configuration objects.

Special configurations regarding the fiscal year of an enterprise, as well as the calendar year, are set up in TPM Year configuration objects.

To inform the OEE Equipment Monitor object about when and why equipment is not scheduled for production and therefore isn’t to be taken into account for OEE calculations, TPM Not Scheduled objects are used.

If equipment, which had been scheduled for production before, had to be unscheduled again, TPM Unscheduled Configuration objects are used to inform the OEE Equipment Monitor object about the times and reasons.

Equipment stops in a production can occur for a multitude of different reasons. If and how the individual Stop Reasons affect the OEE calculations is configured in the TPM Stop Reason Configuration object. By default, all equipment stops affect the OEE Calculations.
Built-in Stop Reasons can be further customized or Userdefined Stop Reasons can be configured for more specific needs.

If OEE Data is to be aggregated, at least one TPM Preset Configuration object also needs to be configured.
