In addition to an ETHERNET interface, WAGO's new Linux controller 750 863 also has a RS-232 interface, which is connected on the front via a D-Sub connector, enabling modems or displays to be connected directly. Thanks to the enlarged 8MB Flash memory, there is space for a larger file system, which means that more applications and data can be stored. This new controller is also a user-programmable fieldbus controller with uClinux operating system, offering a multitude of user-space applications. For Web applications with access to the process data, the integrated Web server has a CGI interface.
