Sistema IIoT para supervisión y control del variador de frecuencia ATV930 mediante la configuración de un PLC y visualización HMI

Abstract

This work presents the design and implementation of a supervision and control system for an ATV930 variable frequency drive, integrated with a Modicon TM262 PLC and an HMI interface, developed during an internship at Schneider Electric S.A.S.. The project focuses on regulating the temperature of an industrial process using a nonlinear PID controller programmed in Structured Text (ST), whose output acts on the frequency reference of the drive. The project included drive parameterization, control algorithm development, scaling of analog and digital signals, alarm configuration, and visualization of critical variables through a Harmony HMI. Additionally, the dynamic behavior of the thermal system was analyzed, considering phenomena such as actuator saturation and the slow response typical of thermal processes. The results demonstrate the feasibility of integrating control and supervision strategies in industrial environments aligned with the principles of the Industrial Internet of Things (IIoT) and Industry 4.0, contributing to improved efficiency and monitoring of industrial processes.
