Smart factory industrial automation system clock synchronization,
General specification for management and measurement
1 Scope
This standard specifies the basic composition, configuration and networking principles of the clock synchronization system for smart factories and industrial automation systems.
It describes the terms, definitions, functions, requirements of clock synchronization systems, and the methods of clock synchronization system management. It also specifies the clock synchronization system
Requirements for measurement test conditions, measurement items, measurement methods, measurement targets and measurement cycles.
This standard applies to working on the basic reference model of open system interconnection specified in GB/T 9387.1 layer 1 ~ layer 2 or layer 1 ~ layer 3,
And the physical layer complies with IEEE802.3 specifications, the data link layer complies with IEEE802.1D and GB/T 15629.2 specifications, and the network layer complies with
Industrial Ethernet switch specified by the Internet Engineering Task Force (IETF) IP protocol cluster.
