标题： RIO EPICS device support application case study on an ion source control system (ISHP)

摘要： 实验物理和工业控制系统（EPICS）是一种软件工具，近年来已成为在大型科学环境中部署分布式控制系统的主干框架。目前，ESS Bilbao使用此中间件来执行其氢正离子源（ISHP）项目的控制。控制系统的设计基于：使用LabVIEW-RT和LabVIEW-EPICS工具的PXI实时控制器；以及基于现场可编程门阵列（FPGA）技术的RIO设备。旨在为RIO设备提供完全符合EPICS的IOCs，并避免系统维护方面的额外努力，已将当前系统迁移至衍生的Red Hat Linux（CentOS）环境。本文介绍了一个实际的应用案例研究，用于使用NIRIO EPICS设备支持（NIRIO-EDS）来支持ISHP。尽管RIO FPGA配置是针对ISHP性能的特定解决方案，但NIRIO-EDS通过将一种明确的设计方法应用于之前的RIO/FlexRIO设备的FPGA配置，使得设备的控制和监控成为可能。该方法使得新的强大、可扩展和易于维护的软件能够快速简便地部署到ISHP控制系统架构中。 显示英文摘要

摘要： Experimental Physics and Industrial Control System (EPICS) is a software tool that during last years has become relevant as a main framework to deploy distributed control systems in large scientific environments. At the moment, ESS Bilbao uses this middleware to perform the control of their Ion Source Hydrogen Positive (ISHP) project. The implementation of the control system was based on: PXI Real Time controllers using the LabVIEW-RT and LabVIEW-EPICS tools; and RIO devices based on Field-Programmable Gate Array (FPGA) technology. Intended to provide a full compliant EPICS IOCs for RIO devices and to avoid additional efforts on the system maintainability, a migration of the current system to a derivative Red Hat Linux (CentOS) environment has been conducted. This paper presents a real application case study for using the NIRIO EPICS device support (NIRIO-EDS) to give support to the ISHP. Although RIO FPGA configurations are particular solutions for ISHP performance, the NIRIO-EDS has permitted the control and monitoring of devices by applying a well-defined design methodology into the previous FPGA configuration for RIO/FlexRIO devices. This methodology has permitted a fast and easy deployment for the new robust, scalable and maintainable software to support RIO devices into the ISHP control architecture.
