Hmmm... Interesting. Probably @Tim Mitsch<mailto:t.mit...@pragmaticindustries.de> has an idea?

I think we have never seen something like that before. The only thing I could think of is GET/PUT not being enabled (via TIA) on the PLC but I’m unsure if that’s already for the connection or only for reads.

I think the exception already happens during the PlcDriverManager.getConnection.

I will try to reproduce it. I think the issue is in the “ping()” method which does nothing “native” but rather uses the “ping” method of Netty’s channel handler. It would be a better test to just do a “read()” on some Field like a Marker or something. Could you try that?

Does the PLC need some special configuration in the project to be reachable via S7Comm via ISO on TCP? nmap shows port 102 TCP as open. Any help is much appreciated!
