The slave has to be on a second machine. Install RTnet on that one as well and configure IPADDR=10.0.0.2 and TDMA_MODE=slave. > > I'm sorry for all these questions, but really the documentation isn't > exaustive ... > Already looked at this diagram? http://www.rts.uni-hannover.de/rtnet/doc.html Already browsed the Documentation folder in the source code or read one of the articles? You first need a basic understanding of the network structure, but then the existing documentation should provide a lot of details. Anyway, we may have failed to state the "obvious" facts, feel free to come up with suggestions what should be explained differently. Jan
