Arrowhead Tools is Europe's largest project for solutions in automation and digitization for the industry. The purpose of the three-year project Arrowhead Tools is to create engineering tools for the next generation of solutions in digitization and automation for the European industry. These tools will bridge the gap that currently prevents a total integration of IT and operational technology, i.e. how the industry works towards the Internet of Things (IoT) and "system of systems"; to build large systems using the Internet of Things. The new technology will be made available through an open source platform, Arrowhead Framework.
