This diagram shows the hardware structures and communication routes in the different booth types. can also be hosted in local networks. Together with the CP6606 as the IoT controller, TwinCAT 3 PLC and TwinCAT IoT establish a seamless connection between the Internet of Things and the Internet of Services in the solution realized by Carheal. In the company’s Smart Repair booths, the analog and digital sensor signals recorded in real-time are sent by means of TwinCAT IoT to the Microsoft Azure IoT Hub at intervals of fi ve seconds, fi ve minutes or ten minutes, depending on the relevance and properties of the information. Among other things, the data provides information about the location and general condition of the booth, the fi lter operating hours, the air quality, the duration of the individual work steps, and the consumption of energy and paint. The system raises the alarm if volatile organic compound (VOC) limit values are met or exceeded. The primary reason for using the Beckhoff control platform is the fact that TwinCAT IoT offers the option to communicate with the Microsoft Azure IoT Hub directly from the PLC logic, even on small ARM-based CPUs such as the one found in the CP6606. The acquisition and evaluation of data in the cloud is currently still new territory for Carheal, but Henrik Bro Christensen expects it to provide him with many advantages when upscaling his business model. The cloud connection makes sense, especially in view of the growing number of Carheal booths and service providers internationally. It guarantees the secure storage of data on various servers all over the world. The data are already being used to measure Key Performance Indicators (KPIs), which provides information on performance and utilisation, and helps improve the service of the Carheal booths. If a workshop operates several booths, data can be compared and potential areas for optimization can be determined. Another advantage is the addition of predictive maintenance functionality. By tracking the measured values from the booth, the operator can tell at an early stage when, for example, fi lters need to be replaced, sensors exchanged or paints refi lled. As a result, maintenance costs can be reduced signifi cantly. Sven Goldstein, Product Manager TwinCAT Connectivity & IoT, Beckhoff Automation.
