- press hydraulic system control – pressure control, speed control or proportional valves
- belt movement control frequency converter drives, bi-directional, constant tension rewind solution
- implementation of press technology – pressure, temperature control, recipe management
The control technology was implemented on the Siemens platform. The user interface is made in WinCC Flexible. The system makes the compression data available via an Ethernet network to the SCADA above, where the data, technology diagram and trend diagram are displayed and stored in a central SQL database.
