Implementación de un sistema automatizado de supervisión y control, que permita evaluar y seleccionar el ensamblaje de materiales plásticos y metálicos basado en IIoT.

Abstract

The objective of this technical project was to implement an automated supervision and control system, which allows to evaluate and select the assembly of plastic and metallic materials based on the Industrial Internet of Things (IIoT) in the Industrial Automation laboratory of the Faculty of Computer Science and Electronics of The Escuela Superior Politécnica of Chimborazo. Stage 1 used a Schneider TM221CE16T programmable logic controller (PLC), pneumatic actuators, a conveyor belt, and sensors to determine the pin type. For stage 2, a Delta DVP 32ES2 PLC was included that activates the coils inside the valves by sensors, giving movement to the pneumatic actuators, in addition to a conveyor belt that takes part to the classification area and holds it by suction cups, classifying them according to the type of pin. The final stage involves supervision and remote control implemented through the WECON brand IIOT Gateway. A V-NET cloud SCADA system was developed using the V-NET ACCESS software. The IIOT device vulnerability analysis was carried out in four phases: the first consisted of collecting relevant information about the system. In the second phase, ports and services were scanned using NMAP. Subsequently, in the third phase, the vulnerabilities detected using NESSUS were exploited. Finally, in the fourth phase, the detection of possible attacks was carried out with the Metasploit tool. As a result of the connectivity tests, it was determined that packets sent in a maximum of 36ms were not lost. Therefore, it is concluded that the network has a minimum communication latency. The vulnerability analysis showed that the IIOT Gateway does not present critical vulnerabilities or available exploits. Therefore, it is concluded that it is not currently possible to attack this device. It is recommended to expand the review of the vulnerabilities in industrial communication devices.
