    This paper towards obtaining an academic degree, develops and implements a methodology allowing the integration and interconnection of heterogeneous processes using an industrial internet of things (IIoT) communication approach in a simulation environment under the concept of Industry 4.0. The protocols used are ,mainly, MQQT and HTTP and operate under the client-server architecture, in addition to filtering information through ,respectively , Publisher / Subscriber and Request / Response events. An industrial-like process is designed through Factory I / O software . An orange juice production line, controlled by a programmable logic controller (PLC). An important aspect is the design of a PID controller to automate the process efficiently. The communication process is implemented with the aid of the OPC server, which refers to a communication protocol in the field of control and supervision of industrial processes. OPC interacts as middleware and allows the connection between each of the levels of the automation pyramid. In such a way, the option of sending information from the factory to the cloud is enabled, in order to monitor the current state of each of the variables involved in the production process. The Node-RED software was used to manage the plant information, in this way, it is possible to establish a link with the database of each of the IIoT development environments, likewise, storing the factory data in real time. In order to carry out a comparative análisis, based on the efficiency of information management, the Wireshark tool was used, thus obtaining different results based on the percentage of lost packets for each communication protocol. For the development of the project, an open source platform known as Thinger.io and a payment model AWS, was utilized. Similarly, a MySQL block is used to capture packets locally. For visualization purposes, an HMI system is implemented in LabVIEW and its respective digital-twin is created in the Node-RED environment with the purpose of: virtualizing the services of the MES layer and providing access to different plant operators. As a result, a fault detection agent is programmed in the multitank system and its operation is linked to a block that issues a notification via email and the interaction between a bot and factory operators to take corrective measures.
