Virtual remote lab for control practices

The present work describes the construction of a virtual laboratory that allows its remote access via TCP/IP. Its client server structure allows it to have control in real time of the process in the server and a complete control and supervision from any place through the Internet. For controlling the process, a series of acquisition and distributed ' control cards which communicate to each other and with computers by means of the RS485 protocol were constructed, the cards have been developed to facilitate laboratory practices of distributed control and virtual instrumentation. The system includes acquisition and control cards, software developed in LabVIEW to monitor the state of the whole system and the application server with ample benefits for processes control.
