Hi Ronnie,

The problem still exists in SVN37570.

$ tshark -v

** (tshark.exe:2932): WARNING **: openSAFETY - SercosIII heuristic dissector
can
not be registered, openSAFETY/SercosIII native dissection.
TShark 1.7.0-SVN-37570 (SVN Rev 37570 from /trunk)

Is this related to bug 5990 (SERCOS III built-in dissector (from plugin))?
https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=5990

Thanks
Joke
