------------------------------------
Hey [~ldywicki],
I am struggling for far too long with setting up a project to use the plc4x-api
and the profinet-driver, so I decided to ask for help:
The project I created that uses plc4j-api and test-java-profinet-driver (both
self install 0.9.0-SNAPSHOT) is a Java module project (contains
module-info.java) and fails to connect:
{{10:42:24 [oioEventLoopGroup-2-1] INFO org.pcap4j.core.NativeMappings - Pcap4J

failure because it has succeeded already:

java.lang.IllegalStateException: close() must be invoked after the channel is
closed.}}
In my main I am running this:
String connectionString =
"profinet-dcp://192.168.0.101?sender=50:65:f3:b8:cd:a3";
try (PlcConnection plcConnection = new
PlcDriverManager().getConnection(connectionString)) {
//... do something with the connection here ..
Is the driver not ready yet to return a valid PlcConnection instance?

> Key: PLC4X-286
> URL: https://issues.apache.org/jira/browse/PLC4X-286
> Project: Apache PLC4X
> Issue Type: Improvement
> Components: Driver-Ethernet/IP, Driver-Profinet, Driver-S7
> Affects Versions: 0.9.0
> Reporter: Adrian Lazar
> Priority: Major
> Labels: beginner, feature, question
>
> I found some work done towards implementing the
> [profinet-DCP|https://profinetuniversity.com/naming-addressing/profinet-dcp/]
> protocol on the [feature/profinet
> branch|[https://github.com/apache/plc4x/tree/feature/profinet]].
> I see that the profinet protocol is not on the develop branch anymore, was it
> replaced with the s7 protocol?
> If someone would have the time to guide me, I could work on it to update,
> test, and bring this discovery feature to PLC4X.
