Abstract :
Scheduling of the communication in industrial networks takes time. Since it has to be carried out every time a new network is brought to work, the time necessary to perform scheduling becomes a prominent factor. The approach presented in this paper, simplifies the scheduling problem of PROFINET IRT by resolving communication conflicts by utilization of the dynamic frame packing (DFP) mechanism.
