MOW03	Integration of Renovated Networking Middleware into a Running Control System Environment	controls, monitoring, coupling, ion-source	37

	Currently the proprietary networking middleware in the GSI control system is replaced by a CORBA based re-design. Rebuilding all controls components is out of scope, so existing applications as well as device specific front-end software still have to be used. The renovated middle layer has to fit between the former applications device access interface and the front-end framework. Providing similar functionality as before was a major design aspect therefore. However, the new outline, targeting more flexibility and clearity, did not completely provide the established functionality from the beginning. Several extensions, had to be added which on the other hand lead to additional capabilities for future usage of the system.

	Beam-loss level monitoring is a powerful diagnostic tool concerning accelerator health. Particles leave the vacuum pipe for various reasons, such as intrabeam scattering (Touschek effect), residual gas molecules, closed orbit distortions or mechanical obstacles (aperture restrictions, installation errors). These can be identified by appropriate measurements. The steady-state beam loss level varies throughout the machine and has to be measured and documented for further reference. Besides general radiation safety purposes, changes (especially increases) occurring after machine upgrades are of special interest. When simple monitoring of average beam loss fluctuations is insufficient, problem diagnostics should be further enhanced by correlating beam loss monitor (BLM) detector readout with events in the machine. For best flexibility, pulses should only be counted at certain conditions and during well defined time slots synchronized with the current machine operation cycle. In cooperation with Cosylab, such an advanced BLM acquisition system was developed for the Electron Stretcher Accelerator ELSA (University of Bonn, Germany), allowing various optimized acquisition modes.

TUP008	Network Analyser for the EPICS Channel Access Protocol		96
	K. Žagar, A. Žagar Cosylab, Ljubljana K. Furukawa KEK, Ibaraki R. Rechenmacher Fermilab, Batavia, Illinois
	In this paper, we present a tool which allows capturing Channel Access (CA) traffic directly off the network and interpreting the contents with a graphical or textual user interface. The tool is the widely used Wireshark (former Ethereal) network capture and analysis application, for which we have implemented a plugin that parses (dissects) contents of CA network packets. The tool is freely and openly available for several operating systems, and we have built and tested the CA plugin for Windows, Linux and Darwin (Mac OS X). We first describe the Wireshark framework, followed by the steps needed to implement a dissector plugin. Then, we present the features and limitations of our CA dissector implementation. Afterwards, we explain how to install and use the Wireshark application and the CA dissector. Finally, we present some examples where we have found the tool to be useful.

	Control systems of modern accelerators, such as RIBF, KEKB and J-PARC, adopt many programmable Logic controllers (PLCs). They are supervised by Input/Output controllers (IOCs) of Experimental and Industrial Control System (EPICS) with being controlled and monitored through Ethernet connections. In this type of control system, the adoption of Ethernet as a field-bus reduces the work load for the development of device/driver support modules of EPICS. On the other hand, having controllers (PLCs) under yet another controllers (IOCs) doubles the work load for the implementation of the front-end software. In order to solve the problem, we developed an embedded EPICS on F3RP61-2L, a CPU module running Linux that can work with a base module and I/O modules for FA-M3 PLC. We found that the IOC program can run without any modifications on the CPU module. This paper describes the details of the embedded EPICS system and the application of the new type of IOC for the control systems in operation and under construction.

WEP014	Processing of Large Data Sets: Evolution, Opportunities and Challenges	survey	198
	I. D. Valova ICSR, Sofia M. Noirhomme-Fraiture FUNDP, Namur
	In the paper are analyzed the applied and theoretical results achieved, as well as some existing drawbacks in technologies for processing of large data sets-OLAP (On-line Analytic Processing), DM (Data Mining) and SDA (Symbolic Data Analysis). A comparative analysis is proposed on different types of data processing and are highlighted the pros and cons of each one of them. Here are discussed benefits and drawbacks at using of data aggregates and visualization of large data set. Some topics of interest are shown for the purposes of additional scientific study, being specifically oriented to software applications.
