The world wide web became a vital element of all human activities by now. The rapid growth of fast and reliable communication networks provides an easy exchange of information and commands between computers connected to sites of wide area networks such as the internet. Engineers/students form far away workstations can operate through the internet with various remote equipment, since integrated web-learning and web-research environment become more and more accepted. Engineering is transformed into a constructive joint effort within the framework of simulation and exploration. Engineers share information at a rapid pace, with the collective aim of increasing product, process and service quality and reducing development time and costs. The internet-based, virtual or tele-laboratory permits experimentation independently of distance, in a way similar to what occurs in conventional laboratories. With the latest technology available, it reaches the same objectives as for a hands-on or conventional research or university laboratory, and even more efficiently in most cases. The application properties now range right up to the internet-controlled visualization of processes far away from the platforms. University of Miskolc Department contributed to the solution of these challenges by a new smart measuring instrument which performs on-line diagnostics of electrical motors developed particularly for design and production divisions of domestic labor-saving devices, and by an internet-based virtual laboratory serving the Ethernet network-based industrial measurement systems to all users through an "open for all" web site by Fieldpoint and General Purpose Interface Bus (GPIB) modules.
