The Data Acquisition (DAQ) of the CMS Experiment [1] is composed by O(10000) network objects spread in O(1000) nodes, most of them based on commodity PCs, connected to a very efficient Local Area Network. The DAQ complex (both hardware and software) must be controlled in order to synchronize all the objects to perform in the proper sequence the needed(More)
A comprehensive model based on XML technologies to interface data acquisition hardware devices for configuration and control purposes is presented. The model builds upon the use of a unified syntax for describing hardware devices, configuration data, test results as well as control sequences. The integration of the model with the online software framework(More)
