Industrie 4.0 and the Industrial Internet Consortium (IIC) have tried to systematically decompose the needs of Industrial Internet systems and define a reference architecture that promotes the desired operational concepts. This endeavor has been focused on Smart Factories for Industrie 4.0, whilst IIC has addressed generic Industrial Internet of Things (IIoT) systems. Their reference architectures, RAMI 4.0 and IIRA, have identified the key technical requirements and some standards that address them. Yet, at times the discussion on applicability leaned towards ecosystem interest, technological protectionism and in some cases a misunderstanding of what a technology such as Data Distribution Service (DDS) really is or can do. This presentation will (1) introduce the key concepts behind RAMI 4.0 and IIRA, (2) introduce the architectural patterns and the key requirements at the foundation of RAMI 4.0 and IIRA as well as their similarities and differences, and (3) explain how the OMG DDS standard can be used to help implement RAMI 4.0 and IIRA compliant architectures.
