Diseño de un sistema automatizado de permisivos aplicados en fábricas de balanceado acuícola.

Abstract

The objective of this degree project was to develop a system for process permits, safety, and startup in an automated aquaculture feed production plant. A programmable logic controller (PLC S7-1500) and Ignition SCADA software were used to develop this system. This enabled the control logic to be tested and verified using PLCSIM, without any process disruption. The system established process conditions, safety interlocks, and startup restrictions, ensuring that equipment cannot operate unless the established conditions are met. This reduced electrical risks, prevented equipment malfunctions, and improved operator safety. A graphical operator interface with pop-up windows was also designed, which facilitated real-time status and condition monitoring, leading to improved interaction between operators and the system. The results obtained indicated a significant reduction in line failures, without the need for a start-up test, and that the time to start the line was guaranteed, making it a technically and economically viable alternative.
