Based on the current trends of industrial applications and internet of things, a distributed system solution is proposed. The work presents a description of used communication methods, connected devices, the support software and the necessary configuration. Low-cost IoT-based sensor augmentation can be used to keep older machines and companies competitive when new equipment is not available for purchase. The main sensor functions of an older industrial controller can be extended by the data, which is measured on the microcontrollers. This is demonstrated on the example of a system solution with detailed set up and configuration.
