  Several attempts have been made to integrate EPICS functionality with National Instruments LabVIEW. With existing EPICS code, labs want to reuse the code while still being able to use LabVIEW to interface with FPGA enabled embedded controllers and other COTS hardware. In this paper, we will show how we can run EPICS IOC simultaneously with LabVIEW on VxWorks based hardware. We will go into the implementation details and the benchmarks that will be obtained from the LANSCE-R project at Los Alamos National Labs. We will also examine ways to implement a Channel Access(CA) server natively in LabVIEW. This will open up the opportunity to use a variety of IO and different operating systems that LabVIEW can interface with. The native LabVIEW CA server will implement all Channel Access functionality exposed by a standard EPICS IOC such as synchronous and asynchronous publishing of data, alarm processing, and response to connection requests by CA clients. We will finally cover the programming of FPGA allowing for custom solutions.

TUX02 Experiences with PVSS II as an Overall SCADA System for ANKA 46

  The control system of the synchrotron radiation source ANKA at Forschungszentrum Karlsruhe was segmented into several autonomous parts. The storage ring have been controlled by the ACS control system, the infrastructure facilities by the supervisory control and data acquisition system (SCADA) named IGSS, and several autonomous PLC based interlock systems for the accelerators and beam lines. Each system required special knowledge for maintenance and failure diagnostics. In order to improve the manageability and to reduce cost, the SCADA system PVSS II has been chosen as a supervisory control system, integrating each of the individual parts. As the interface is open and easy to handle the integration was straightforward. The majority of the existing control systems have been integrated with limited man power during a one year period followed by a continuous optimization process. The new system with a common look and feel for beam lines and machine was quickly accepted by beam line scientists, technicians and operators.

TUX04 j5 Logbook - A Commercial e-logbook 52

  j5's EventStream module provides an interface for exchanging data with services such as Tango and OPC. j5 models this data as a series of events. Each combines information on the source of the data, its reliability, when it was generated and whether it represents an alarm condition, with the actual data from the external device. Adding a new type of data source requires only the implementing of the very modest data device API. For Tango, the implementation built on PyTango while for OPC Windows COM was used. Data devices support both pulling values and subscription to event channels. Once in j5, events may flow through event pipes, being transformed and triggering actions such as the addition of logbook entries. In other cases, j5 may pull events from the data server, e.g. to populate data fields automatically when new log entries are created. A key feature enabled by EventStream is the ability to attach graphs of 1D and 2D arrays directly to logbook entries as they are added. This combines the event processing capabilities of j5 with its document attachment and thumbnail generation to make the information present in such arrays immediately available to logbook users.

WEP005 Monolithic DAQ System for Beam Diagnostics at the HIT Medical Accelerator Facility 177

  The Heidelberg Ion Therapy Center HIT is presently in the final phase of commissioning. HIT consists of a two-stage linac followed by a compact heavy-ion synchrotron. The ion beam can be delivered to two horizontal treatment places and a gantry structure for 360° patient treatment. In this contribution we report on the basic concepts for the integration of the beam diagnostic data acquisition into the overall accelerator control system and the distributed timing devices. The equipment-side abstraction layer of facility-wide device classes and its seamless integration besides device control units, e.g. for power supplies, is presented and first operational experiences of the machine commissioning are discussed. As examples for the data acquisition of the high-energy beam transport section the detection of beam profiles using MWPCs and Scintillation Screens is presented, as well as measurements of beam intensity using ionization chambers.

WEP006 BeamView - A Data Acquisition System for Optical Beam Instrumentation 180

  At the GSI accelerator facility, several optical beam instrumentation devices for transversal profile measurement are installed. Their readout is done with FireWire CCD cameras attached to a small embedded device, specialized for image processing tasks (National Instruments Compact Vision System 1456). Here a LabView application preprocesses the images based on user requests. The resulting data (e.g. projections, histograms, compressed or original images) is sent over ethernet to a Windows or Linux PC, reaching frame rates above 30fps at VGA resolution. Using C++ with Qt libraries for networking and GUI purposes, platform independence without source code modification is achieved. In this paper we present the system components and software design to control CCD cameras and various other devices with an easy-to-use graphical user interface for machine operators.
