[I] [Bug]: Unable to connect to PLC
pquiring opened a new issue, #1958:
URL: https://github.com/apache/plc4x/issues/1958
### What happened?
PlcConnection plcConn = PlcDriverManager.getDefault().getConnectionManager().getConnection("s7://10.48.61.20);
Method never returns. Using WireShark I can see TCP connection was established but no data is transmitted.
Not sure why some output is not in english.
OS : Windows Server 2022
Java : 17
Netty : 4.1.63 (last one that included -all build -- alternative is to include 40+ deps - foobar!)
Here is log output:

I use the maven artifacts so I can wait until 0.13 is released. Trying to debug as well in the mean time.
Thanks,

Hi,
Please use version 0.13.0-SNAPSHOT, if you use a single CPU it should solve your problem.
I'll be looking forward to your comments,

Tried with Netty/4.1.116.Final (modules:-common,-buffer,-transport,-handler,-codec) and get different results. Now the connection fails and returns immediately.

The S7 driver was completely rewritten ... Claude marked this issue as obsolete. Closing it for that ... if you still happen to run into this, please feel free to open a new issue after testing with the 1.0.0 version (-SNAPSHOT or the full version after it's released)

The problem with that approach is that we can't 100% guarantee that it's fixed in 0.13.0. If you test it now, we have a chance of fixing it for the next release. Otherwise it will be a while till the next one. Snapshots are also available as maven artifacts. All you need to do is add the apache snapshot repo to your pom.
