PROFINET CBA (PN-CBA)

The PROFINET CBA (PN-CBA) protocol is a field bus protocol related to platform independent data exchange.

PN-CBA is based on DCOM and the "lightweight" PROFINET/RT (Ethernet type 0x8892) protocols:

  • The connection management part is using DCOM as its underlying protocol.

  • The acyclic data transfer (transfer of data if value changed) also uses the DCOM protocol.

  • The cyclic data transfer uses the "lightweight" PROFINET/RT protocol.

History

XXX - add a brief description of PROFINET CBA history

Protocol dependencies

Example traffic

XXX - Add example traffic here (as plain text or Wireshark screenshot).

Wireshark

The PN-CBA dissector is fully functional.

Preference Settings

There are no PN-CBA specific preference settings.

Example capture file

XXX - Add a simple example capture file to the SampleCaptures page and link from here. Keep it short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically.

Display Filter

PN-CBA splits into several DCOM interfaces, so there's no single PN-CBA filter available. A complete list of PN-CBA display filter fields can be found in the display filter reference, look for all protocols (DCOM interfaces) beginning with the cba_ prefix there.

For this reason, theres no simple PN-CBA filter. However, you can filter on the underlying DCOM protocol.

  • Show only the DCOM (PN-CBA) based traffic:

     dcom 

Capture Filter

You cannot directly filter PN-CBA protocols while capturing.

  • the PROFINET CBA Architecture Description and Specification can be found at http://www.profibus.com -> downloads -> specifications and standards

  • add link where to find additional info on the web about PN-CBA
