Posted 23 Sep 2015 Hello: Is there any off-the-shelf Wireshark dissector for Melsec TCP which can decode the TCP portion of Melsec TCP traces? Thanks. Share this post Link to post Share on other sites
Posted 24 Sep 2015 Sorry, but I've never seen that. Not many people debug the TCP stack. Share this post Link to post Share on other sites
Posted 24 Sep 2015 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. Share this post Link to post Share on other sites
Posted 12 Oct 2015 (edited) 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.
