Integrated projects

Automation modifications and upgrades together with machine improvements or relocations are always implemented according to customer needs. Integrated automation projects vary from individual components or principle drawings to full-scope automation deliveries of entire machine section rebuilds.

Case: PLC upgrade at Stora Enso Skoghall board machine 8, Sweden

We have had a good working relationship with the Valmet check-out team during rebuilding, check-out and commissioning. The system solution and its rebuilding turned out well, and our operators are very pleased with the HMI panels. All the people involved from Valmet deserve big thanks for a well-executed project.”
