    The present research work used an "MPS Station" and a "Conveyor Station", the same ones that were equipped with the necessary IoT instruments and technologies for their association to industry 4.0, in order to monitor an industrial process locally. and remote, for this it was seen the need to implement a LAN network for the assignment of IP's to the equipment that will be part of the process; The S7-1200 PLC was programmed using the Modbus TCP/IP communication protocol, where it performs the master function and the other devices act as slaves, thus sending information to the master, a Raspberry Pi that hosts the Home Assistant operating system, with which Orders are given to the PLC through control buttons, which are distributed in a graphical interface, the operating system allows cameras to be integrated in order to transmit video in real time with the idea of monitoring the process, a voice assistant such as Amazon's Alexa and in this case the Google ssistant, for the recognition of the three colors a file was developed in Python, the communication with Home Assistant was used the MQTT protocol. The programming of a database in Home Assistant for the creation of a file that houses the date and time of the piece that was selected according to its color, where its results were as expected, the control and monitoring of the stations in a way local complied with all the selected orders from the graphical interface located on a PC, the control and monitoring of the stations remotely complied with all the selected orders from the graphical interface found on a cell phone, in the case of the assistant Voice did not comply with all the orders since it depends on external factors such as noise, environment of the place, the speed of the internet. The IoT system is applicable to a large-scale industrial process since in local control and remote control it meets the requirements, in the case of the voice assistant it must be under a controlled environment.
