Abstract:

Background: With the development of computer technology and Ethernet technology, programmable logic controller (PLC) has the ability to access Ethernet with its Ethernet communication module, so the device controller can be connected directly to the Ethernet 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 Ethernet connection are widely used in SSRF device control system whilst other control devices are connnected to EPICS by developing Ethernet API. Conclusion: The Ethernet technology ensures good reliability and easy maintenance of the SSRF device control.
