The implementation of software based OPCUA servers on computing platforms in actuators and sensors of the field layer remains a challenge due to the protocols high memory and bandwidth prerequisites. This paper discusses encoding aspects of OPC UA binary data representations for devices with limited random access memory and low fieldbus throughput, especially focusing on single-chip microcomputing...
The design of conventional process plants is guided by the idea of structuring the process in functional units. Because of cost reduction this design is often neglected during the implementation phase. There is a huge potential in the re-modularization looking at the re-usability which directly effects the engineering efficiency when developing new plants. Furthermore, there is the possibility to...
