Device integration into automation systems by means of an embedded web interface

Web-technologies which came up in many fields of automation seem to be a solution which improves device integration in many ways. On the one hand the used Ethernet improves the installation techniques with reliable and approved network cables and routing devices. On the other hand the used internet protocols provide several services for the application software development. The following article is intended to explain several aspects of device integrations using an embedded Web server. As a practical example, concepts and results of a new developed communication module called EWI are given to demonstrate the improvements in measurement device integration in the field of automotive test bed automation.
