Description

Technical field:

[0001] The present invention relates to a real-time synchronous communication network for industrial field-level communication, in particular to a real-time synchronous network based on standard Ethernet, which is used to solve communication problems in field-level communication systems, that is, how to solve the problem of using Ethernet for field-level Real-time communication and precise synchronization of the system are realized when the communication system is used. Background technique

[0002] At present, in the field of factory automation and process automation, fieldbus is the mainstream solution in the field-level communication system. However, with the continuous progress and development of technology, the traditional fieldbus has shown its own limitations more and more. On the one hand, with the continuous improvement of the intelligence of field devices, the control becomes more and more decentralized, and the control data needs to be exchanged ...
