Abstract

See full text

Method for time synchronization in a network between at least one master and at least one slave, which is an interrupt-capable network component and uses a timer, which accesses a slave time to generate at least one interrupt recurring at a predefined cycle duration, at a respective trigger point in time that is synchronized with the slave time. When a synchronization message arrives, a time offset between the master time and the slave time is determined in the slave, and a time fraction is determined from the time offset, which corresponds to an integer multiple of the predefined cycle duration of the at least one interrupt. An interrupt offset is then determined from the time fraction and the time offset. At least one time jump is carried out by a synchronization unit in the slave to correct the time offset.
