Abstract:
1. A method for transmitting data in an automation system for controlling machines and installations, the automation system comprising a first automation network component and at least a second automation network component, said automation network components being formed via at least one automation network for cyclic data transmission using a communication protocol on which the respective automation network is based for the purpose of data transport and being connected to one another, the method comprising: using a fragmentation controller to divide that data to be transmitted into a plurality of fragments; sending the fragments with a fragment information item using in each case one fragment message via the respective communication protocol from the first automation network component to the second automation network component; confirming by the second automation network component the reception of a fragment contained in the respective fragment message in the fragment information item of the fragment message, wherein a fragment is transmitted cyclically using a fragment message from the first automation network component until a fragment message with a reception confirmation contained in the fragment information item is received by the first automation network component; and assigning priority channels to both the first automation network component and the second automation network component, wherein the fragments are assigned in the priority channels corresponding to their priority which they have obtained from the priority of their data.
