Hello!
I am currently working with a system that communicates using LON. The system is based on a PL3120. In order to test the system we must be able to send and read specific messages over the LON network. The source code for the PL3120 is already written (by others) and all messages that are sent are broadcasts.
So, what we need is:
- An adapter which allows a PC to send and read broadcast messages (with a specific payload) on a LON network.
- A command line interface for this. We will write automatic test cases that will be run using robot framework.
Is this possible to achieve with the U10 or U20 USB network interface?
Take a look at NodeUtil which is a diagnostic tool that can be used to communicate to a LonWorks device. You can use any Echelon Network Interface including the U10 or U20.
The latest at this time is NodeUtil (3.23)

Yes, you can send and receive management-, diagnostics-, nv- and explicit messages with OpenLDV and a U10 or U20 interface. If you need a software stack, please contact me.
Best regards
