| Abstract: | Nowadays the distributed control system is used in most of large accelerator control systems. The system exchanges various kinds of data on the network. Since the control operation and data access require the CPUs to be regulated based on time, a time system is very important for the distributed control system. This paper describes the time protocol and its principle used in the time synchronization system, and introduces how to use software to build the system and to test its precision. |
