If in the beginning only computers could connect and communicate with each other, the idea of Internet of Things (IoT) or Industrial Internet of Things (IIoT) pushes technological evolution to the next level, making possible the connection to the Internet of all the devices created for this purpose. Industrialization 4.0 is the latest industrial revolution, and is not based on the discovery of a new form of energy, but on the digital world or digitization, due to the continuous development of computers, sensors and the mass generalization of the Internet. This article provides an overview of the minimum requirements for migrating from Industry 3.0 to the first step of the Industry 4.0 concept, by highlighting the possibilities of communication between production and management lines, the advantages brought due to their interconnection and the management of the collected data using a Manufacturing Execution System (MES).

INTRODUCTION Manufacturing and beyond, needed innovation in order to be able to cope with the new demands of the modern world, where access to information is easy everywhere through the use of the Internet [9]. Starting from this idea and using the same communication environment, the latest industrial revolution, known as Industry 4.0 (I4.0), wants to open a new path regarding the informational exchange of production processes. It is talked about the possibility of interconnecting the sensors, devices and production lines with people through a central system (software) that can analyse productivity in real time, based on the data collected from them. Also, the process can be considered reversi-ble, in the sense that the software can send data to the production line, so that it can be able to satisfy the imposed requirements. Industry 4.0 represents a fusion of several ad-vanced technologies under the same concept, each of them having a well-defined role in achieving this idea, Fig. 1: Internet of Things, Cloud Computing, System Integration, Simulation, Additive Manufacturing, Autonomous Robots, Big Data, Augmented Reality [1].
