Hi, As I just mentioned in slack, it would be good to find other sources of information. As the mentioned drive is gpl licensed, looking at the code and writing code from that would be regarded being a derivative work. We could write a program using the driver and inspect the packets it writes and reads. That would be OK.

With the help of my beloved Tim, Matthias and Björn we at least found out that there seems to be a proprietary protocol called DF1 (“ControlNet, DeviceNet oder Remote-E/A-Kommunikation. DF1 Halbduplex-Master-Protokoll gewährt die Steuerung von SCADA Netzwerken über Modems“). There also is an open source implementation online under https://github.com/leicht/Df1/tree/master/src. My question is, has anybody already some experience with this PLC or with the protocol? I think its reasonable to implement this, but would be good to have some feedback upfront. I logged JIRA PLC4X-131 for that [1]. Julian [1] https://issues.apache.org/jira/projects/PLC4X/issues/PLC4X-131?filter=allopenissues
