Design of an Electronic Coupling to Control Speed of Motor on a Conveyor Belt Using IoT

An advanced production ecosystem, automated and interconnected by the development of new technologies in industrial systems is known as Industry 4.0. The contribution of different technologies supported by cyber-physical systems whose principle of operation is to monitor and control manufacturing processes through computer-based algorithms connected to the Internet. this allows to have a Machine-to-Machine (M2M) communication system supervised and controlled for decision making. This paper will focus on the update of the design and construction of an electronic coupling device for making Industrial Internet of Things (IIoT) connections in a conventional Programmable Logic Controllers (PLC). In this work a SIMATIC S7-200 PLC is used, where a Nodemcu Esp8266 WIFI card is coupled through the inputs and outputs of the device to monitor and control the shifting process of a product distribution hand. A method is proposed to modify the speed of motor using an HC-SR04 sensor to determine the amount of material corresponding to the PLC.
