The data of the core automation welt is exported via open interfaces like OPC-UA to the system world for monitoring and optimization tasks. Where necessary, it can also be fetched directly with the help of a second communication channel to the existing field devices. Additional sensors in the area of monitoring and optimization can be integrated easily by NOA into the open system world. “It is not the end of the world, if an optimization software for a pump does not have the same availability as the core automation. Obviously, they must work reliably, but not with the same stringency”, said Klettner.
The objective of NOA – NAMUR Open Architecture to enable the use of innovative technologies and thus increase the economy of the plants. Because eventually the aim of Industry 4.0 still is to increase throughput and reduce costs. How this can function was illustrated with the help of two use cases: In one case, cost-effective additional measurements were installed to predict the Fouling behavior in a heat exchanger.
These sensors are not required for the online process management, so that an installation in the core automation would be unnecessarily expensive. In a second use case, the special sensors delivered along with a big machine were connected directly to the plant asset management system of the machine supplier – without being integrated in the core automation. Finally, emphasized Klettner, there can be no compromise on plant availability and plant security. But open system interfaces are required between process control tasks and the monitoring and optimization. Here, the approach for new production plants as well as for existing production plants – and as always, automation security is an integral component. At noon numerous workshops hooked up.
