A modern IT infrastructure is the backbone of future-oriented data utilization. Industry-typical brownfield environments present companies with major challenges in the area of data acquisition on a daily basis. In order to overcome these and to be able to exploit the enormous potentials through data analysis and data mining techniques, we deal with technologies for data acquisition and shop-floor connectivity. This ranges from MES, LIMS and ERP systems to IIoT frameworks. Within this environment, the connection of a wide variety of digital interfaces (e.g. OPC-UA, MQTT, EUROMAP), the storage of data in central database systems and related decentralized technologies (e.g. distributed ledger), as well as the provision of data for analyses and other services are central topics. For this purpose, we use many different systems in our labs with the goal of a fully connected shop-floor, which are available and accessible as demonstrators.
