Nowadays, the industry is witnessing the revolution called Industry 4.0. Many manufac‐turing industries are jumping to this new technology, Industrial Internet of Things (IIoT) to improve performance and efficiency in their processes. However, some industries do not want to jump to this new era due to big changes. That is where this project comes in, being its aim to create a CPS from an existing process, working with IIoT. In order to accomplish this, Mosquitto, CoDeSys, ThingSpeak and MQTT Dashboard, as well as Simumatik are going to be used to create a communication system based on three layers. The development of the project is based in adapting sensors and actuators to IIoT in Simumatik, configure all the connections between services and programming inside CoDeSys and Thing Speak, as well as creating an MQTT Dashboard inside a mobile application. Once the project has been developed, some conclusions could be taken out, such as easy scalability and cheaper implementation, con‐suming less wire and less PLC modules, although it is needed cutting edge technologies tools to process all data and find ways to optimize a process.
