Desarrollo de una Interfaz Gráfica con LabVIEW para la Planta T5555

Abstract

Using a graphical interface with LabVIEW software, which will act as Data Client, it is intended to communicate with the pressure plant of Amatrol T5555. Which has a Simatic S7-1200 PLC, in which will be the programming done TIA PORTAL of Siemens (Ladder) for the control of the plant. Acting as well as a data source. The solution to this communication will be made through the NI OPC Server (communication protocol) provided by NATIONAL INSTRUMENT. One of the most outstanding advantages of this software lies in being able to communicate different PLC's of different types of manufacturers with LabVIEW. This is how, after having the graphical visualization done in LabVIEW, the input variables, activated by the user with OPC Server, are interconnected so that the latter can deliver the activation signal to the program previously loaded in the PLC. Part of the project development is the design of laboratory practices that involve the programming, communication and operation aspects that were necessary to develop control of the T5555 Plant. This programming interface interacts with the user interface allowing to enter values ​​of Set point level, turn on and off the pump that drives the liquid, select types of experiments (level and pressure) and also visually monitor levels and alarm states.
