With such topics as Smart Shipping and Industrie 4.0, SMM is once again making a name for itself as the world's leading trade show for the maritime industry. Beckhoff presents its PC- and EtherCAT-based control technology at the biennial exhibition for the marine industry. Designed for industrial use, PC-based control has also been tried and tested in building automation for the past 15 years. Since the topics of energy efficiency and digitisation are becoming increasingly relevant for the shipbuilding industry, PC-based control technology is showing its merits in this application area. Due to its openness, modularity and scalability in terms of performance, size and price, this technology is ideally suited to control applications in various areas: In addition to lighting, the intelligent control of heating, air conditioning and ventilation as well as individual room control – on passenger ships, for example – it’s also possible to integrate measurement technology, engine monitoring and condition monitoring flexibly and cost-effectively into the control platform. At the same time, specific software modules such as TwinCAT Analytics for the seamless recording and analysis of process data and TwinCAT IoT for simple and secure cloud communication facilitate the realisation of big data applications and Smart Shipping concepts.
