摘　　要：在EPICS下建立了采用EtherNet/IP协议的ControlLogixPLC测试系统,分析了ControlLogix的EtherNet/IP在EPICS环境下驱动程序的实现原理及软件层次结构,解决了现有驱动程序的不足之处,最后进行了ControlLogixEtherNet/IP通讯性能的测试,结果表明它在数据传输的实时性、稳定性、可靠性等方面有良好的性能。This paper describes the establishment of a ControlLogix PLC system under EPICS environment. The implementation of ControlLogix EtherNet/IP driver for EPICS and its layers are discussed. Solution for the deficiency of the EPICS driver is presented. Results of the EtherNet/IP testing show that the system which uses EtherNet/IP has good performance in regard to speed, stability and reliability.
