Author: Karásek Vladimír
The Simulator of the FDL(Field Data Link) layer of PROFIBUS protocol is created for educational purposes. It is intended for those who desire extend their knowledge in the field of industrial communication. This simulator helps to understand the PROFIBUS specification. Reading specification requires concentration, patience and a certain level of a field bus background. The simulator reduces all these demands on people willing to get through specification. Students can observe behavior of the bus in various situations. It includes state transfer of nodes and communication between nodes. It is possible to achieve error conditions of the bus, for example a deadlock or a token loss.
