OPC Unified Architecture OPC UA and CIM Important requirements: Applicable to extended CIM models (because in many cases deployed models include numerous enterprise-specific objects) Platform-specific model (PSM) as basis: All CIM-information will be preserved Stereotypes are used to annotate UA-specific information Design decisions can be stored and loaded Handle new versions by difference models Tool-Support: Add-In for Sparx Enterprise Architect (the tool which is used to maintain the CIM) 03.12.2018
