Abstract

A method for transmitting data in an automation network by telegrams, where the automation network comprises a master subscriber, slave subscribers and at least one unlocker, connected to each other via a data-line network. The slave subscribers are divided into segments. The master subscriber sends locked telegrams for processing by the slave subscribers, each having a telegram identifier used to assign a locked telegram to a segment. At least one segment is assigned to at least one unlocker. If the unlocker receives a locked telegram, the unlocker checks, by the telegram identifier in the locked telegram, whether the locked telegram for the assigned segment is intended to release the locked telegram, as an unlocked telegram for processing by the slave subscribers, provided that the locked telegram is intended for the segment assigned to the unlocker.
