Abstract (EN): This paper provides a comprehensive study on how to use Profibus networks to support real-time communications, that is, ensuring the transmission of the real-time messages before their deadlines. Profibus is based on a simplified Timed Token (TT) protocol, which is a well-proved solution for real-time communication systems. However, Profibus differences to the TT protocol prevent the application of the usual TT analysis. The main reason is that, conversely to the TT protocol, in the worst case, only one high-priority message is processed per token visit. The major contribution of this paper is to prove that, despite this shortcoming, it is possible to guarantee communication real-time behaviour with the Profibus protocol.
