Controls interface protocols for the SSC correction and 'DC' magnet power supplies

The control, monitoring and diagnostic requirements of power supply systems determine the required functionality (or transactions) and response of the interface protocol. Advances in technology allow increased functionality of front end control equipment and therefore relatively sophisticated interfaces are required. The protocols to be used must be capable of supporting functionality upgrades. The command response type protocols standardized on earlier are no longer adequate. This paper describes the interface protocol to be used between the SSC Corrector and 'DC' magnet power supplies and their respective controllers. Factors affecting protocol definition and constraints placed by cost and availability considerations are described as well as an implementation strategy.<
