    The main purpose of this research was to develop an automation of the profile cutting process of the company CONSTRUALVID by means of programmed logic and intelligent IOT systems, in order to provide an adequate and innovative tool for the operation of this process. For the development of the proposed automation, a PLC S7 1200 1212 AC/DC/RY was used, in addition to a Xinje TouchWin HMI screen, which were programmed in TIA Portal and TouchWin Tool Edit respectively. As for the axis control, this is done using a Siemens signal board and it is programmed in TIA Portal through the technological objects that it offers. For the remote control of the process, the Siemens SIMANTIC IOT 2050 module is used, in which our local NODE-RED server is installed, being these together responsible for acquiring and sending data from the PLC to the UBIDOTS cloud server and vice versa. The alarms are displayed both locally on the HMI screen and remotely via a text message via Telegram. To keep track of the past events of the process, it is connected to the Firebase cloud database. The results achieved from the intelligent system are significant and in this way a functional system with a robust structure was obtained for the efficient development of the profile cutting process. On the other hand, for the remote control and monitoring system, very acceptable data was obtained mainly from the transmission and reception time of data from the UBIDOST cloud server to the PLC, resulting in times of 0.77 and 0.94 seconds respectively, as for the time of writing data from the PLC to Telegram and Firebase a time of 0.79 and 1.17 seconds was obtained respectively, which represents a quick response to a possible event. Finally, with the implementation of the system, an efficiency of 98.7% and a user (operator) satisfaction level of 95% was achieved.
