Node-synchronizing method for synchronizing network nodes in a sub-network synchronizes the timers for a network's network nodes with micro-second accuracy

摘要

One network node (NK1) takes on the function of a network master, the real time of which is used as a reference time for a sub-network to be synchronized. The master first makes sure that there is no unauthorized communication during subsequent processing stages in a sub-network. The master transmits a runtime test telegram to each network node in the sub-network to determine signal runtime.
