Supervisory Control and Data Acquisition Laboratory

SCADA systems became popular to arise the efficient monitoring and control of distributed remote equipments. This paper presents practical laboratory set in Supervisory Control and Data Acquisition (SCADA) systems. Practical labs introduce gradually the main SCADA elements and develop an application to control an induction motor in interlocked manual/automatic mode, with touch-screen Human Machine Interface (HMI). The SCADA concepts are implemented on an integrated automation system with distributed periphery using Democase from Siemens. The system illustrates trends, alarms, motor frequency and automatic sequence of motor speed profile.
