Abstract
In an internet assisted laboratory (online I-lab) the lab devices and pilot plants are tested, controlled and programmed through a client program or simple web browser at a remote computer. A user-controlled webcam allows monitoring the devices or pilot plant behavior. As an online lab can be used from many locations and at any time, it can be utilized much better than a conventional lab. By working with an online Internet accessible Lab, students and researchers shall not only carry out experiments but also learn how to work, program and design remotely monitored and controlled devices and processes. Online labs will support distributed group work over the Internet. Software to control and program the lab devices and pilot plants runs on central server. Furthermore, user lab access rights will be administered there or on delegated machines called service brokers. Work assignment text and hypermedia course material for the experiment are available from the same site over the Internet. The paper presents one online Internet accessible laboratory built at the Faculty of Electrical Engineering in Sarajevo within the laboratory for HMI/SCADA systems. Pilot plant constitutes of three tanks level control system controlled by Siemens Simatic S7-300 PLC controller. Web enabled HMI software with OPC communication to PLC controller is used to provide full monitoring and control to remote user over pilot plant operation.
