Ok, I'll try to reach someone via phone tomorrow.

This is the "smaller" one:

and the bigger one:

I also attached both to this email.

While playing around with TwinCAT today I also saved a PCAP-dump of the
slave initialisation (i.e. right after scanning for a usable NIC and
while scanning for boxes within the system manager), maybe you can use
it: http://nwl.cc/~n0-1/twincat_init_device.pcap .

Greetings, Phil
