Method for integrating systems with only one sync domain for time and cycle synchronisation into a global time synchronisation domain

摘要

The method involves determining an operating clock (216) of sync slaves (218, 224, 230) by information supplied in a single domain-internal synchronization message (212) about the operating clock. The operating clock of the sync slaves is represented as a system-intrinsic operating clock (222) of the sync slaves, where a subordinate domain (236) remains unchanged for an integration of the domain into a higher-ranking domain of the operating clock. A timing clock (204) of the subordinate domain of an automation network is directly synchronized with a timing clock of the higher-ranking domain. Independent claims are also included for the following: (1) a computer program product comprising a set of instructions to perform a method for synchronizing an operating clock with a timing clock of a subordinate domain of an automation network (2) a device for operating clock-and time clock synchronization of a subordinate domain of an automation network.
