ibes13 opened a new issue, #1257:
URL: https://github.com/apache/plc4x/issues/1257
### What happened?
We would like to establish a connection to a S7 plc, tested it with the
following plc types
- S7 1500 (CPU 1515F-2 PN)
- S7 315
A connection is established for a short time in which we can also read out
data from the plc before a DisconnectEvent appears.
```

org.apache.plc4x.java.s7.readwrite.connection.S7HMuxImpl.userEventTriggered(S7HMuxImpl.java:184)]
(executor-thread-2) DisconnectEvent
```
Has anyone ever had this problem ?
The connection to our plc works normally with the Moka7 library
```
try(PlcConnection connection = new
DefaultPlcDriverManager().getConnection("s7://"+serverUri+"?remote-rack="+rack+"&remote-slot="+slot);){
}catch(Exception ex){
ex.printStackTrace();
}
```
```
