Hard Real-Time Capable OPC UA Server as Hardware Peripheral for Single Chip IoT Systems

The fast semantics project examines the use of the OPC Unified Architecture (OPC UA) in embedded industrial systems and proposes the design of a customizable, hard real time capable OPC UA Intellectual Property Core (IP Core) for single chip computing plattforms. This allows using OPC UA in both novel energy efficient sensor applications and in state of the art field devices. These single chip OPC UA servers form the semantic data sources for future applications such as cloud based added value services or machine learning applications. This article presents the design alternatives and first synthesis results for the implementation of OPC UA servers in embedded systems.
