Entity names in MES

When Entity Model Builder creates entities, it creates the new entity names using the TagName attribute in the source application object. Note that entity names in MES support up to 80 characters while the application objects support up to 128 characters. Only the first 80 characters will be used for the name in MES.

As discussed in the entity creation example, if the following System Platform equipment model was exported, it would produce two Entities: Bearing_Plant which is a parent to Assembly_ Area.

+ Bearing_Plant (Area)

+ Assembly_Area

+ Station1

AAS_1_SQA_1

The export is non-destructive and it creates new entities and entity hierarchies that don't already exist. If an OEE/Utilization entity or the job execution entity already exists, it may be overwritten with new OEE/Utilization data and/or job execution data. However, an existing entity will never have any capabilities removed. This includes OEE/utilization and job execution capabilities.

Note: Entity Model Builder will first use the UCO and then use the OCO to create/update the entity in the MES database. Entity Model Builder can possibly overwrite the entity if an OCO and UCO exist under the same application object.
