The CERN control protocol for power converters

The CERN Control Protocols provide, for a class of similar devices, a unique and standard access procedure from the control system. Behavioral models have been proposed for the different kinds of power converters, and the corresponding functionalities, with their parameters, variables and attributes, have been identified. The resulting data structures have been presented using the ISO ASN.1 metalanguage, which permits universal representation independent of any computer environment. Implementations in the UNIX-based CERN accelerator control systems are under development. A description of the implementation phase as it is presently being developed at CERN in a cluster of 120 power converters is presented.<
