Types of sensors: how machines see, detect and communicate smartly

Categories: Innovation and trends in plastic materials, Plastics industry market reports and analysis

Over the last 30 years, the Industry 3.0 has been based on a well-defined automation architecture consisting of five layers. Field devices such as sensors and input/output devices at the lowest layer send data to logic controllers through analogue signals. SCADA systems perform remote control tasks and Manufacturing Execution Systems (MED) allow users to carry out complex tasks such as production scheduling. Finally, at the highest layer, ERP systems allow to generate management reports and share manufacturing data, such as the state of the order, with other systems such as the Customer Relationship Management (CMR). 

In Industry 4.0, these layers become diffuse due to Cyber-Physical Systems (CPS), the direct evolution of embedded systems, which offer the possibility of decentralized data processing, Edge Computing or Cloud Computing.
