Abstract
A method for data transmission in an automation system from a second field device via a first field device to a receiver, wherein, at the first field device, a first data subframe is created, a second data frame is received from the second field device, and a first data frame including the first and the second data subframe is sent correctly-timed by Dynamic Frame Packing to the receiver. In the event the second data subframe is unable to be appended directly to the first data subframe at the latest after the correctly-timed sending of the first data subframe, the sending of the first data frame is shifted by a time value, where the time value is calculated so that immediately after the sending of the first data subframe, the second data subframe is able to be appended directly to the first data subframe.
