MTControlledVocabEventType

All \glspl{MTDataItem} with \gls{category} \mtmodel{EVENT} having Controlled Vocabularies (Enumerations) will be added as sub-types of this type which is mapped to the OPC/UA MultiStateValueDiscreteType. Otherwise, either \mtmodel{MTString} or \mtmodel{MTNumeric} will be used. All subtypes are direct representations of the MTConnect equivalent elements that can be found in the MTConnect Part 3 \cite{MTCPart3} documents.
