This requires integrating a wide variety of control points from different rooms and floors of the Livermore accelerator facility at a single operator station. The control system adopted by the commercial vendor of the accelerators relies on the National Instruments cRIO platform, so that hardware system has been extended across all the beamline and experimental components. Here we present the unified, class-based framework that has been developed and implemented to connect the operator station through the deployed Real Time processors and FPGA interfaces to the hardware on the floor. Connection between the deployed processors and the operator workstations is via a standard TCP/IP network and relies on a publish/subscribe model for data distribution. This measurement and control framework has been designed to be extensible as additional control points are added, and to enable comprehensive, controllable logging of shot-correlated data at up to 300 Hz.
