EPICS（实验物理和工业控制系统）是一种广泛使用的可扩展控制系统。在 GSI，HADES 小组自成立以来就使用 EPICS [1]。为了在 EPICS 上构建 GSI 广泛的知识库，启动了除 HADES 之外的一些其他项目。例如，FOPI 是不同控件开发的一个不错的目标，例如基于 LabView 的 CS [2] 和 EPICS。对于 CBM 的 FUTURE DAQ 项目和 HADES tdc 读出板，“嵌入式”EPICS 将移植到这些嵌入式板。 EPICS简介 EPICS是一个开源控制系统框架，它允许构建巨大的分布式控制系统。它可以在多种 OS（操作系统）上运行，例如 Linux、Vxworks（最初在此操作系统上开发）、RTEMS（实时操作系统）和 Windows。通信基于使用以太网作为传输层的通道访问（CA）协议。 IOC（输入输出控制器）是通过 CA 提供过程变量 (PV) 的应用程序。 PV 发布后，它就在网络范围内可见。 EPICS 可以自由地使用任何 CA 客户端来显示获取的数据。 GSI 目前使用 MEDM（Motif 编辑器和显示管理器）作为默认解决方案。但在不久的将来，将测试显示 CA 数据的其他方式。除了显示之外的任何其他服务，例如归档、直方图和警报处理，都可以作为 CA 客户端使用。这些工具可以在中央网页 [3] 中找到。 EPICS 有完整的文档记录并可在万维网上获取。除此之外，非常活跃的电子邮件列表“技术谈话”还可以让您了解全球 EPICS 用户的广泛知识。对于第一次启动参考 [3] 是评估 EPICS 的最佳起点。为了从所有计算机上访问 EPICS，在 Linux 上启动了 GSI 广泛安装。详细的操作方法可在 [4] 中找到。所有实验组都被邀请测试 EPICS 的设置。
EPICS (Experimental Physics and Industrial Control System) is a widely used scalable control system. At GSI the HADES group uses EPICS since its startup [1]. In order to build a GSI wide knowledge base on EPICS some other projects than HADES are started. For example FOPI is a nice target for different controls developments like the LabView based CS [2] and EPICS. For the FUTURE DAQ project of CBM and the HADES tdc readout board an “embedded” EPICS will be ported to these embedded boards. EPICS a small introduction EPICS is an open source control system framework which allows to build huge distributed control systems. It can run on several OSs (operating systems) like Linux, Vxworks (originally developed on this OS), RTEMS (A real time OS), and Windows. The communication is based on the channel access (CA) protocol using Ethernet as transport layer. The IOC (Input Output Controller) is the application which provides process variables (PV) via CA. Once a PV is published it is network wide visible. EPICS gives the freedom to use any CA client to display the acquired data. As a default solution MEDM (Motif Editor and Display Manager) is at the moment used at GSI. But in the near future other means of displaying CA data will be tested. Any other service than displaying, like archiving, histograming, and alarm handling are available as CA clients. These tools can be found at the central webpage [3]. EPICS is fully documented and available on the world wide web. In addition to that the very active email list “tech-talk” gives access to the wide knowledge of the worldwide EPICS users. For the first start reference [3] is the best starting point to evaluate EPICS. In order to have access to EPICS from all computers, a GSI wide installation was initiated on linux. A detailed HowTo is available at [4]. All experiment groups are invited to test EPICS for their setup.
