ABSTRACT:
The invention relates to a computer-implemented diagnostic procedure for a field bus system in which bus users exchange data via a field bus in accordance with a predetermined communication protocol, the data being exchanged in the form of data packets, comprising the following procedural steps: (a) recording states of the bus users; (b) detecting a data packet which is transmitted via the field bus between the bus users; (c) analyzing the data packet and deriving an updated state of the bus users in dependence on the preceding state of the bus users and the content of the data packet; (d) recording the updated states of the bus users; (e) repeating steps (b) to (d) in order to detect the current states of the bus users in an in-line manner.
