Wireshark dissector for S7 communication. This Wireshark dissector plugin (dll) dissects the ISOonTCP-packets for communication to Siemens S7 PLCs.

IMPORTANT
The s7comm protocol is directly integrated into wireshark (also sources), you don't need the plugin anymore, if you use an actual version of Wireshark.

To build s7comm-plus for the S7 1200/1500 plc, use the latest sources from Wireshark. Or if you want to use the plugin dll, use the most recent version of Wireshark you can find.

Thank you. :)
  • Great plugin and author is responsive with support
  • A "must have" for everyone that needs to communicate with S7.
  • Great plugin to analyze S7 communication. Little remark: I had to disable protocol T.125 "T.125 (Multipoint Communication Service T.125) before Wireshark detected " under "Analyze-Enabled Protocols" in wireshark before S7comm packets were recogized as such. It took me quite a while to get this. So others should be warned.
