Hello: Is there any off-the-shelf Wireshark dissector for Melsec TCP which can decode the TCP portion of Melsec TCP traces? Thanks.

Sorry, but I've never seen that. Not many people debug the TCP stack.

Hello, The protocol is documented in several manuals. I made a spreadsheet that breaks apart a few commands. PM me an email address and I will send it, if you want it.

Hello Mark: Thanks very much for your offering. I will contact you through your website. I will delete this post after I get your e-mail. I am interested in developing like a LUA dissector for Melsec. I am not sure whether I will succeed, but if I do I intend to share it with the world. Rgds. Edited by PLC_guy_in_Yokohama
