Local standalone controllers, such as the u-control web, can perform their control tasks independently and without additional devices. They offer benefits compared to central solutions in a wide range of applications: They reduce system-wide data traffic, are resistant to interferences within the network, make troubleshooting easier and are very well suited to being combined with manual processes. Especially for this application, new flexible control concepts are required, which can be used according to the “Plug and Play” concept. As a rule, however, plants are often equipped with one and the same type of control system, usually according to specifications. On the one hand, this is practical because the same hardware and function blocks are always used. On the other hand, however, greater effort is required to keep adapting them – and sometimes only for one project. u-control web as an open web-based controller simplifies the programming process for standalone applications. It integrates real-time automation and communication for the Internet of Things and thus forms the ideal interface between the previously separate worlds of Information Technology (IT) and Operational Technology (OT).
