A bottling line consists of a filling module (switchable between 2 fillers and 4 fillers), a capping module, a labeling module, and a transport system. The production line is provided via an OPC UA endpoint for control and monitoring purposes.

In the context of enhancing productivity and sustainability, the goal is to operate the bottling line in such a way that production is further increased when sufficient or surplus renewable energy is available. The backend system checks periodically a Smart Grid endpoint (via HTTP) how the current power production is and how much renewable energy is produced. Based on the bottling line's current power consumption, which is measured via Modbus, the backend system decides to increase productivity when surplus renewable energy is available. In doing so, the backend system interacts via OPC UA to release the 4 fillers of the filling module and increases the speed of the transport system. If the backend system detects that less renewable energy is being produced, it will initiate standard production and reduce the transport speed and return the 2 fillers of the filling module.
