A network stream capture tool has been developed to monitor and capture control data and information encapsulated in network stream for distributed control systems for high energy accelerator control systems. The tool allows capturing data streams between specific computers, and dumping the stream data into a file. The data can be browsed using graphic user interface (GUI), either binary, ASCII, UTF-8, and hexadecimal formats to analyze and debug communication protocol employed among computers for the control systems. The tool has been implemented using Java, and thus ported to various platforms, including Linux, Solaris and Windows, providing versatile functionality necessary for multi-computer control systems. This paper describes design and implementation of the network stream capture tool in detail.

A reconfigurable embedded interface system has been developed using micro-controllers for high energy accelerators. The system has up to 28 digital I/Os and 8-channel AD converters(10 bits), interrupt functions allowing control systems to access any accelerator components over the network. The components involve beam-position monitors, current monitors for bending magnets, ion pumps, vacuum valves, insertion devices, RF components, ion-gauges, and beamlines. The interface is programmed to carry out specific tasks in accordance with requirements for experiments and research purpose. The interface employs PIC micro-controllers, and it can be connected to the network. The interface is easily reconfigured using its boot-loader by uploading a new program from the remote distributed control system through the network. The test of the system has been successfully carried out for a monitoring system for AC power consumption at the control room of B-Factory, KEK. The design and implementation of the reconfigurable interface embedded system for high energy accelerators are described in this paper.
