Introduction
The document discusses the integration of new paper machine drive control systems at UPM Nordland Papier, the largest papermaking complex in Europe. The upgrades aim to enhance reliability, streamline spare parts management, and reduce lifecycle costs.

Background
UPM Nordland Papier faced challenges with outdated drive control systems, which were becoming difficult and costly to maintain. The mill's three paper machines, built between 1969 and 1977, required modernization to ensure continued efficiency and productivity.

Technological Integration
The integration involved the use of Profibus DP high-speed interfaces, enabling direct integration of drive controls into the existing control network. This setup allows for enhanced troubleshooting capabilities and supports older drives through serial and analog links.

System Configuration
The engineering configuration was streamlined using a single, name-based configuration language, reducing long-term maintenance costs by standardizing spare parts. The operator interface integrated drive controls with MCS and DCS controls, providing diagnostic windows for quick fault identification.

Implementation and Results
The upgrades were preceded by a Factory Acceptance Test (FAT) to ensure system functionality. The commissioning of PM 1 and PM 2 occurred during scheduled shutdowns, avoiding production losses. PM 3's system was successfully started in September 2006. The upgrades resulted in improved system transparency and diagnostics, with positive feedback from operators and managers.

Conclusion
The integration of MetsoDNA technology into UPM Nordland Papier's drive control systems has consolidated machinery and process controls, enhancing efficiency and reducing maintenance challenges. The project highlights the importance of technology renewal in maintaining papermaking efficiency and extending the lifecycle of production lines.
