How to find specific databyte in CIP PCCC protocol?

  • retag add tags

Hi, I need to check if some network slave has generated an error by analysing a WireShark .pcapng logfile. I need to find if the first byte of a PCCC command data unequals value 0x10. Is this possible?

Do you have a capture file you could share on a public file share and add a link to it here?

S4x15 - Digital Bond's S4 conference 2015
Capture file MicroLogix56.pcap 10M MicroLogix has cip.pccc fields.

The first byte of PCCC Command Data is cip.pccc.cmd.code.
Display filter: cip.pccc.cmd.code != 0x10
