【摘要】 在加速器控制系统中,PLC大量应用于慢控制和联锁控制。随着工业控制技术的发展,PLC通常采用基于以太网通信方式与上层计算机进行数据交换。采用日本横河公司的FA-M3 PLC和新型CPU模块F3RP61,搭建了一套PLC与EPICS通讯的样机即基于F3RP61的嵌入式IOC。在F3RP61上运行嵌入式EPICS IOC核,使安装了F3RP61模块的FA-M3 PLC成为一种新型的嵌入式IOC,从而将FA-M3 PLC中的I/O数据直接纳入EPICS系统中,简化了系统的结构,降低了开发成本。更多还原

【Abstract】 Programmable logic controllers(PLCs) are widely used to realize the slow control and interlock control of the accelerator control system.Along with the development of the industrial control technology,data exchanging between PLC and upper computer is usually based on the ethernet communication.An embedded IOC prototype was built for communication between PLC and EPICS using the YOKOGAWA FA-M3 PLC and a new CPU module F3RP61.The embedded EPICS IOCCore was run in F3RP61,which makes the FA-M3 PLC with F3RP61 becomes a new type of embedded IOC.Therefore,the data of the FA-M3 PLC can go straight into the EPICS.This framework makes the structure of the control system simple.As a result,the development costs will be reduced.更多还原
