S-LINK Wikipedia

In the Technical Proposals for the ATLAS, CMS and ALICE experiments at CERN, there is a requirement for several thousand data links. Although there is an obvious need for standardisation, this seems difficult to achieve as the links run at different speeds, over different distances and have various constraints of power consumption, size and radiation hardness. An additional complication is that today one cannot decide which will be the most cost effective technology for the implementation of the final links.s-link Furthermore, one must allow designers of boards at each end of the link, for example read-out electronics and input buffers, to work in parallel with the development of the links. The S-LINK is a new concept which should provide the benefits of standardisation without these limitations. The S-LINK specification defines, at both ends of the link, a simple FIFO-like user interface which remains independent of the technology used to implement the physical link. The physical link provides transfer of event data and control words, error detection, optional flow control and test facilities. The paper describes the S-LINK specification and gives examples of the use of the S-LINK, the physical links being designed, and the test equipment that is being developed. Because of the high degree of evolution of recent automation-unmanned technology, the number of sensors and actuators at work in the FA worksite is increasing evermore. ON / OFF switching devices such as photoelectric sensors, inductive proximity sensors, electromagnetic valves, and the like, though simplistic in character, represent a huge burden on the workplace in the form of electricity layout design and wiring when used in large quantities. Can ever increasing quantities of ON / OFF switching devices be wired in a fast, easy and compact way? Panasonic Industrial Devices SUNX's as the leading FA sensor maker, has the answer the S-LINK V.
