Abstract:
1. A method for data transmission in an automation system from a second field device via a first field device to a receiver, comprising: creating, at the first field device, a first data subframe comprising process data of the first field device; receiving, at the first field device, a second data frame from the second field device, the second data frame including a second data subframe with process data of the second field device; and correctly-timed sending, from the first field device to the receiver, a first data frame comprising the first data subframe and the second data subframe by Dynamic Frame Packing; wherein, in an event of the second data subframe being unable to be appended directly to the first data subframe no later than after the correctly-timed sending of the first data subframe, the sending of the first data frame is shifted by a time value; and wherein the time value is calculated so that immediately after the sending of the first data subframe the second data subframe is appendable directly to the first data subframe.
