Abstract. In presented paper we describe engineering design and implementation of an information system based on IoT approach for remote collection, storing and processing information on the number of carried out mechanical cycles for group of older existing fatigue test machines in an automotive components production. The modernization of existing test machines infrastructure we built on the electronic counter modules with developed Ethernet interface. We carried out three ways to verify of accuracy of this manner counting and collecting of mechanical cycles and we reached results comparable with manual collecting of data. Thanks to automatic detection of ends of fatigue tests we reached more effective utilization of test machines (more than 25%).
