Greetings,

the Profinet IO interpretation seems to get something wrong.
See the screenshot attached, left side 0x10 it's FF, right side it's 11. Which
changes the reported protocol to PN-CBA all for sudden.

This is not true, this byte is part of the "real" profinet data (i only changed
the value of a PLC tag). It has nothing to do with protocol type.

Thanks

Daniel
