In this section the use and role of the Arrowhead Framework in large multifunctional industrial automation environments is discussed. The basic scenario is related to enabling industrial IoT and connectivity of devices in a process industry setting. The basic motivation for the Arrowhead Framework - to facilitate the interoperability of IoT devices - is discussed in the light of practical pilot examples. The pilots are from the mining industry focusing on various examples related to maintenance. These examples were chosen due to the frequent wear in mining production equipment and the difficulties associated with traditional condition monitoring for production equipment scattered over long distances. Consequently, the new IoT solutions for gathering and analysing data in the mining industry have high potential for lowering maintenance costs and increasing the availability of production equipment.
