Hi Jonas,
could you perhaps help me? I had several chats (real ones with a phone and
zoom) with the folks from Beckhoff yesterday.
Turns out the ADS Spec doesn't describe so-called SUM requests, where you can
read/write multiple addresses in one request.
In order to generate some traffic with these features, I wanted to use the
Beckhoff Java driver to produce some traffic.
Unfortunately I seem to be unable to get the Java driver to work as the DLL is
missing stuff ... what did you do to set it up?

I believe so, it also gives you possiblity to run under linux and other
embedded devices in secure fashion. :-)
If you can use wireshark take a look if your requests are coming out.
For me they were sent but they never got an answer. This is clear
indication that you are missing an ADS route.
Cheers,
Łukasz
