Ljusne Fish Farming produces salmon for release in Ljusnan, a river that flows into the Baltic Sea. The release of salmon in Ljusnan is carried out by Fortum Sweden as a mitigating measure for disadvantages in connection with the development of hydropower.

In this connection, Fortum Sweden and Ljusne Fish Farming have ordered 91 Poro automatic feeders with associated control systems from the company MK-Tech in Meisingset. The control of the machines will take place through so-called Profinet, a communication method which is an open industry standard that can easily be integrated into a PC through an ethernet cable.

- The choice of supplier was easy as we have had good cooperation over many years with both Knut and Morten in MK-Tech, say Ulf Larsson and Peter Østling at Ljusne fish farming.

10 cabinets are to be built that all communicate to the PC through Profinet through just one cable through all cabinets. A manual timer is also placed in each cabinet, which kicks in if the PC should fail. The entire system with all components is built from scratch in Norway. The order is for well over one million NOK.

- For us, this is a large order, and we are learning that precisely the fact that we tailor everything and that we focus on open industry standards is appreciated, says Knut Grimstad at MK-Tech.
