Desenvolvimento de um Sistema Scada para Controle de Nível de Tanque

Abstract

Nowadays, every industrial process has the need to be monitored or controlled aiming for, mainly, a best quality, the reduction of operational costs and a higher production performance. In order to meet this demand, are used the SCADA systems (Supervisory Control and Data Acquisition), which collect and store data process and shows it to the operator in a great array of ways in the computer screen at the same time that it generates the feedback of what needs to be changed in the process. This paper presents the development process of a SCADA system with the holding of a case study focused on the problem of tank’s level control. Starting by the realization of a study about the architecture of the system, followed by the installation and configuration of the field instruments, like the levels sensors and the control valve, heading to the configuration and programming of the PLC using the LADDER language and finishing with de development of the supervision station using the software Elipse E3, and after that using SCADA Pampa, a supervisory system developed, in Java, within this paper. To validate the proposed solution, was performed the monitoring and control, real-time, of the tank’s level through both systems, making possible to compare the system’s functionalities.
