DNP Malformed Packets and Write, Unknown

Hi,

I am trying to understand a DNP3 trace from an Outstation (DNP3 server).

  • Some outstation frames are showing as "Response [Malformed Packet]"
  • Noticing an unexpected "Write, Unknown Object type" from the outstation to the client.

Could this be a dissector error in Wireshark or is this a true protocol implementation error in the outstation?

Regards,
