Data Visualization With Data Browser Software

International audienceScientific facilities need to visualize a large amount of data through several dedicated applications. They can monitor variables from a PLC, visualize data acquisition or browse them offline. Thus, an intuitive GUI is necessary to handle multiple data sources. In 2012, SOLEIL** computing team started the Data browser development. It uses modular and extendable frameworks on which several institutes collaborated: - CDMA (Common Data Model Access) initiated by ANSTO**** and maintained by SOLEIL developers, unifies the access to data regardless of its physical container (files, databases) or its logical organization. - COMETE (COMmunity of Extendable Toolkit for Experiment) framework, initiated by SOLEIL, provides data visualization widgets and unifies the way there are connected to the data regardless of its source. Since then, SOLEIL developed several plugins for Data browser: HDF/Nexus, Tango*****. Recently, IRFU* control software team decided to use this software for EPICS*** data and to collaborate with SOLEIL. Data browser integrates new EPICS plugins: Channel Access, Archiver Appliance

EPICS Java Developments

International audienceThe IRFU*/DIS software control team is involved from feasibility studies to the deployment of equipment covering low level (hardware, PLC) to high level (GUI supervision). For our experiments, we are using two mains frameworks: - MUSCADE, a full Java in-house solution embedded SCADA dedicated to small and compact experiments controlled by PLC (Programmable Logic Controller), only compatible with Windows Operating System (OS) for the server side. - EPICS**, a distributed control systems to operate devices such as particle accelerators, large facilities and major telescopes, mostly deployed on Linux OS environments. EPICS frameworks provides several languages for bindings and server interfaces such as C/C++, Python and Java. However, most of the servers also called IOC*** developed in the community are based on C/C++ and Linux OS System. EPICS also provides extensions developed in Java such as the EPICS Archiver Appliance, Phoebus Control-Studio**** (GUI), and Display Web Runtime (Web Client). All these tools depend on CAJ (a pure Java implementation Channel Access Library). Today, MUSCADE users use to work under Windows, and they need intuitive tools that provide the same features than MUSCADE. Thus, research and development activities mainly focus on EPICS solution adaptation. It aims to explore further CAJ library, especially on the server side aspect. In order to achieve this goal, several developments have been carried out since 2018

EPICS Tools for Small Experiment Based on PLC

International audienceIRFU* software control team is involved from feasibility studies to equipment deployment into many different experiments by their size and running time. For many years, IRFU is using PLC solution for controlling part of the experiment, and two different SCADA: - MUSCADE, in-house SCADA dedicated to small experiments. - EPICS** for big facilities. With MUSCADE, IRFU has developed a set of tools that gives an easy and a fast way for PLC developers to configure the SCADA. As EPICS projects are growing in our department, we are working now on adapting those tools to EPICS: - PLCParser, which generates an EPICS database for PLC communication (S7PLC, Modbus). - CAFEJava (Channel Access For EPICS Java) API, which runs a simulated EPICS IOC to test EPICS synoptic, and provides EPICS process variables access for any Java application. - Dxf2Opi, which converts Autocad DXF files into OPI files for CSS*** software. - MOONARCH (Memory Optimizer ON ARCHiver Appliance), which reduces EPICS Archiver Appliance**** data files storage
