Desarrollo y simulación de un controlador electrónico basado en PLC S7-1200, LABVIEW Y TIA PORTAL.

Abstract

The development and simulation of an electronic controller based on the S7-1200 PLC, LabVIEW and TIA Portal, controls an electric fire pump and a jockey pump, designed to respond to significant pressure level drops, respectively. Both controllers, although independent, are monitored and controlled centrally, allowing their status to be known, events to be recorded, remote tests to be performed and disabled when necessary. The configuration of the electric pump controller, protected by a password, is performed from an HMI screen, ensuring that only authorized personnel can make adjustments. The integration of these advanced technologies ensures a robust and efficient system, improving safety and operability in emergency situations. In the simulation of the pumping system, a Ladder-type coding integrated into the TIA PORTAL is used for the activation of the jockey pumps and main pump, in conjunction with the block-type programming of LABVIEW. For communication with UBIDOTS, a solution is integrated through a TCP/IP protocol integrated in LABVIEW by sending values by the publication method to a specific address within the server. In the simulation level link between PLSIM, a program to run the PLC locally without having to have it physically, and LabView, OPC servers are used that connect through a communication link on port 502 with the Net to PLC program. The focus of this work is for the student to learn the concept through a simulated environment and without the need to acquire equipment focused on the correct operation of pumping systems.
