You can't reliably detect that across an arbitrary TCP/IP network
connection.
I presume you mean it can't be detected if it's plugged in again
somewhere else? As you say below, if it's not plugged back in it should
be detectable...
What happens if the DTU is plugged into a separate IP subnet and gets a
new IP address assigned? Does this simulate a disconnect and then reconnect?

If I unplug a dtu, I can't find any events anywhere (like in the log
files) until I plug it back in and reconnects.
Generally it takes up to twice the 'timeout' time specified in the
auth.props(4) file (i.e. up to 2x240 sec = 8 min) until the
authentication daemon gives up on a non-responsive connection. When
that happens it will internally disconnect the DTU and any associated
utaction will fire.
If the network connection is temporarily interrupted and restored, the
connection may be simply resumed where it left off. (AFAIK the DTU
gives up on the old connection sooner than the server does, so this
may not be possible for the full 8 min.)
