First version of a DDS/OPC-UA bridge
Real-Time Innovations (RTI) and Xilinx are showing a first demo of an OPC-UA/DDS bridge application. The original version of the Smart Manufacturing Reference Platform which Xilinx has developed uses OPC-UA and two Zynq systems-on- chip (SoC) to demonstrate monitoring and control of motors. One SoC is connected to a motor, a second SoC is connected to an HMI which shows that the motor data is communicated via OPC-UA. RTI is working with Xilinx to extend the platform to include DDS.
In the platform demo DDS connects a third Xilinx computer connected to a strobe light. Data is communicated via DDS to the second gateway node that is also receiving OPC-UA data. So RTI and Xilinx are providing an OPC-UA/DDS bridge application on the gateway node that bridges both protocols.
“The All Programmable Industrial Control System (APICS) highlights key elements of the Xilinx Industrial IoT strategy. This strategy combines software intelligence, hardware optimization, any-to-any connectivity, real time control with multilayer security and functional safety in Zynq SoCs and UltraScale+ MPSoCs,” said Christoph Fritsch, Director of Industrial IoT, Scientific, and Medical markets at Xilinx. “As we expand the capabilities of APICS via this phase 2 implementation at embedded world and Hannover Fair 2017, we are excited work with RTI who is committed to enable secure real-time communications at the IIoT Edge. RTI’s expertise to bridge the two dominant communication standards for Industrial IoT and Industry 4.0, DDS and OPC UA enable our customers in factory automation, energy management, healthcare, robotics, industrial transportation, and smart cities to realize more intelligent, secure, and interoperable systems.”
Background of this work is the recently published Industrial Internet Connectivity Framework (IICF) document by the Industrial Internet Consortium which offers guidance on connectivity standards for IIoT systems. It assesses four core connectivity standards, two of them are DDS and OPC-UA. Part of the connectivity reference architecture is to have standard bridges between core connectivity standards. As the OMG (Object Management Group) is developing a new standard for bridges between DDS and OPC-UA, this demo is showing an initial version of a DDS/OPC-UA bridge.
