Hi Stavros, and welcome to our cool little project list :-)
As I mentioned on SO I would assume that it should be simple to implement Modbus RTU as in general it should just be a different encapsulation and the serial transport, we already have (or in case of RTU over TCP well that should be the same as RTU over Serial, just using the TCP transport. I just checked and all my PLCs except the S7 device support RS458 so I guess I should be able to experiment with it. The only problem is "time" ... So, if anyone here in the community or even perhaps you, Stavros, want to get started on this ... go ahead. Chris Von: Stavros Nikolakopoulos <snikolakopou...@maseurope.com> Gesendet: Freitag, 16.

We love the Scrapper<https://plc4x.apache.org/users/tools/scraper.html> feature and we would like to use it if the Modbus RTU over TCP was implemented. -- Stavros Nicolakopoulos Senior Software Engineer [logo7] Address: 92 Kifissou Ave., Athens GR 10443 E: i...@maseurope.com<mailto:i...@maseurope.com> │ W: www.maseurope.com<http://www.maseurope.com/> T: +30 210 4014000 │ F: +30 210 4001652 [cid:image002.png@01D732C2.3504F300] P Please consider the environment before printing this e-mail Disclaimer: This e-mail is confidential.
