摘　　要：随着工控技术和以太网技术的发展,可编程逻辑控制器(Programmable Logic Controller,PLC)基本都具备了以太网连接功能。上海光源(Shanghai Synchrotron Radiation Facility,SSRF)大量采用了PLC作为设备控制器。应用以太网技术在上海光源设备控制中,通过以太网技术可以使设备控制器直接连接至控制网络。采用以太网技术简化了控制系统结构,同时也便于系统维护和升级。Background： With the development of computer technology and Ethernet technology, programmable logic controller （PLC） has the ability to access Ethemet with its Ethernet communication module, so the device controller can be connected directly to the Ethemet network. Purpose： The aim is to apply the Ethernet technology for the accelerator device controller to the upper-level control system. Methods： The Shanghai Synchrotron Radiation Facility （SSRF） control system is based on the large-scale software EPICS （Experimental Physics and Industrial Control System）. The EPICS communication is mainly based on Ethernet technology. Control devices are connected to the EPICS either by their self-contained driver or by implementation of the approriate Ethernet application program interface （API）. Results： PLCs with Ethemet connection are widely used in SSRF device control system whilst other control devices are connnected to EPICS by developing Ethernet API. Conclusion： The Ethemet technology ensures good reliability and easy maintenance of the SSRF device control.
