APIX industrial for distributed control panel applications
By Christian Eder, congatec and Markus Römer, Inova Semiconductors
Remote touchscreens and control displays typically require a bunch of cables for video, power and control data. APIX concentrates all signal and power lanes in a single standard Ethernet cable to increase implementation flexibility and to decrease overall system cost.
The automotive pixel link (APIX) technology combines high-speed digital video transfer with full duplex, two-wire data communication, and even supports the supply of remote displays over the same cable. Based on this technology, APIX industrial offers a standardized connection of remote displays over single twisted-pair cables without sacrificing the flexibility necessary to meet the application-specific requirements for communication between graphics unit and display. Industrial applications have always required an easy interface for the operator. Traditional human machine interfaces, such as buttons or control sticks, combined with small information panels, are increasingly being replaced or extended with digital displays. When equipped with a touchscreen, displays allow for dynamic screen content and act as an intuitive operator interface. With PC functionality available as small-sized, power-saving modules based on Intel Atom processors, control units can easily take care of the content of the digital user interface. Unlike office applications, the user interface for industrial automation applications is mostly located at a distance from the control PC. Industrial long-distance applications require expensive special cabling or use multiple PCs, connected via Ethernet, for each panel...
