Assignee: B&R INDUSTRIAL AUTOMATION GMBH
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 17:
18. A real-time network system comprising:
a number of components having ports, wherein the number of components are connected to one another via the ports;
the number of components being configured to send synchronization packets to connected components, wherein one of the number of components is designatable as a synchronization master and a remainder of the number of components are configurable using the synchronization packets to synchronize a local network time for the remainder of the number of components, respectively, with a local network time of the synchronization master;
the number of components being arranged to define a synchronization path so that, starting from the synchronization master, synchronization packets are sent to connected components along the synchronization path to synchronize the local network times of the remainder of the number of components along the synchronization path with the local network time of the synchronization master,
wherein the number of components is configured so that, at a time a respective component sends a synchronization packet, a time stamp of the local time of the respective component is transmitted with the synchronization packet, and
wherein, when a synchronization packet is received, the components are configured to calculate a difference time for a port from a difference between the time stamp received in the synchronization packet from the connected component and a time stamp of the local time in a receiving component when the synchronization packet is received, and
wherein the remainder of the number of components are configured to synchronize respective local network times of the connected components via the difference time.
