A new, real-time, distributed, control and data acquisition system architecture for long duration fusion experiments was developed based on the new optical communications technologies and the “System on a Chip” methodology. The architecture integrates data routing, data storage, real-time data processing and control and data acquisition nodes, interconnected by a switched-packed, gigabit, point-to-point, communications network. The routing nodes provide connections to the autonomous storage and processing nodes through standard network links. The control and data acquisition nodes are connected to the routing nodes by specifically designed optical links which provide both data transport and timing/synchronism support. The acquired data are time stamped and can be dynamically processed for local control or sent to the external storage, the real-time processing or the control nodes. The standard processor and the reconfigurable field programmable gate array included in each node allow the programming of the data reduction, adaptive signal processing, and control algorithms from a high level system description language. All nodes will be controlled through an instrumentation-specific implementation of the Extensible Markup Language. A control and data acquisition node with 32 independent and galvanically isolated analog channels of 16 bits resolution is under development. All input signals are continuously and simultaneously sampled at a rate of 2 MSPS, time stamped, optionally digitally filtered, and stored in a large circular memory buffer. Three other node configuration sets will also be implemented: 16 channels, 20 MSPS, 16 bit; 8 channels, 100 MSPS, 12 bit; 2 channels, 1 GSPS, 8 bit.

In order to synchronize the elements of the EAST Neutral Beam Injector (NBI) spatially located in several places, a distributed Timing System (TS) is developed in this paper.The timing system provides a clock reference for synchronization and an interlock protection of the EAST NBI system. It sends timing signals to field devices, controls the pulse widths of the timing sequences, and provides a sampling clock for the Data Acquisition System (DAS). The timing system also generates analog waveforms to control power supplies and gas supplies according to the operator's configuration. The timing system is developed on a PXI (PCI eXtensions for Instrumentation) platform consisting of a LabVIEW workstation and a timing control terminal. The timing control terminal consists of a timing node and several control interface crates. Two timing nodes are configured in one beam line. Each node is responsible for the timing sequence, analog generation and feedback control for one ion source. The architecture and implementation of the timing system are presented in this paper.
