The Experimental Physics and Industrial Control System (EPICS) is a software environment used to develop and implement distributed control systems to operate devices such as particle accelerators, telescopes and other large experiments. EPICS also provides SCADA capabilities. The tool is designed to help develop systems which often feature large numbers of networked computers providing control and feedback.

dbpprop:abstract
  • The Experimental Physics and Industrial Control System (EPICS) is a software environment used to develop and implement distributed control systems to operate devices such as particle accelerators, telescopes and other large experiments. EPICS also provides SCADA capabilities. The tool is designed to help develop systems which often feature large numbers of networked computers providing control and feedback. EPICS uses client/server and publish/subscribe techniques to communicate between the various computers. One set of computers (the servers or input/output controllers), collect experiment and control data in real-time using the measurement instruments attached to it. This information is given to another set of computers (the clients) using the Channel Access (CA) network protocol. CA is a high bandwidth networking protocol, which is well suited to soft real-time applications such as scientific experiments.
  • EPICS (für Experimental Physics and Industrial Control System) ist eine Softwareumgebung, um verteilte Kontrollsysteme für Großexperimente wie Teilchenbeschleuniger oder Teleskope zu entwickeln und zu realisieren. EPICS bietet dabei SCADA-Unterstützung. EPICS verwendet Client-Server- und Publish-Subscribe-Methoden für die Kommunikation zwischen den verschiedenen verwendeten Computern. Eine Sorte von Computern, die Input/Output-Controller (IOC), sammelt dabei in Echtzeit über die angeschlossenen Messinstrumente Experiment- und Kontrolldaten. Über ein spezielles Netzwerkprotokoll namens Channel Access (CA) werden diese Informationen an eine weitere Rechnersorte, die Clients, weitergegeben. CA unterstützt dabei weiche Echtzeit-Anforderungen, wie sie in wissenschaftlichen Experimenten anfallen.
  • EPICS（Experimental Physics and Industrial Control System）は、加速器、望遠鏡、その他の大規模は実験用機器を運用する分散制御システムを開発・実装するのに使われるソフトウェア環境である。EPICS は SCADA の機能も提供する。このツールは、多数のコンピュータからなるネットワークで制御とフィードバックを行うシステムの開発の補助となるよう設計されている。アルゴンヌ国立研究所が2004年に開発したもので、独自のオープンソースライセンスでリリースされている。 EPICS は、コンピュータ間の通信モデルとしてクライアントサーバモデルと出版-購読型モデルを採用している。コンピュータ群（サーバまたは Input Output Controller）が、付随する測定機器を使って実験データと制御データを収集する。この情報を Channel Access (CA) というプロトコルで別のコンピュータ群（クライアント）に送る。CA は広帯域のネットワークプロトコルであり、科学実験のようなリアルタイム性を要する応用に適している。
