A network device for industrial control includes at least one processor, configured to operate a first operating system (OS) to process data forwarding with TSN standards and operate a second operating system to operate with an industrial protocol to process industrial control; and a communication protocol processing module, coupled to the at least one processor, configured to process network traffic of the first operating system and the second operating system according to a synchronized time. The first operating system and the second operating system perform time synchronization through a time message to obtain the synchronized time.

Network device and time synchronization method thereof

A time synchronization method for a time synchronization device, wherein the device is connected to a plurality of time synchronization domains through a plurality of ports, and the plurality of time synchronization domains use a plurality of PTP profiles. The method comprises determining whether each of the plurality of ports is a time receiving port or a time transmitting port; obtaining information of a grandmaster clock of the plurality of time synchronization domains; performing information conversion on the information of the grandmaster clock according to a PTP profile corresponding to each time transmitting port of the plurality of ports in the plurality of PTP profiles, so as to generate a plurality of clock information corresponding to each time transmitting port; and transmitting a corresponding clock information of the plurality of clock information to a corresponding time synchronization domain from each time transmitting port, so as to perform time synchronization.
