Wireshark-users: [Wireshark-users] Simatic H1 protocol

Has anyone out there successfully decoded this using wireshark?

For me, it comes up as a COTP frame inside a CLNP header but doesn’t break down any further. If I disable these decoders and just run with the H1 enabled the packets show as unknown??. Now this is a really old installation (I’m talking thicknet and ancient S5 PLC’s here).

Any advice would be greatly appreciated.

Cheers
