When Dansk Traeemballage (DTE) looked at how to increase the precision and productivity of its sawmill one of the major challenges was to establish the right automation control network. As the biggest producer of wooden packaging in Denmark the plant includes over one hundred inverter drives, all of which needed to be controlled simultaneously and in real-time. The technology used was CC-Link IE, the only open gigabit Ethernet designed specifically for industrial automation tasks DTE's sawmill is located in Ribe, Denmark and dates back to 1581. It is now the mainstay facility for the company's pallet production activity. Everyday, approximately 35 trucks bring conifer logs to the saw line to produce lumber, resulting in over 300,000m~3 of raw timber being processed every year. This is then exported or distributed across DTE's five production sites to obtain 150,000m~3 of finished wood that is used to assemble crates and pallets.
