Hey, fine, if you are already in contact with CC then its fine nonetheless (Chris is on holiday currently).

Sounds perfect. I have a call with Uwe in 15min anyway. I will then ask Chris for access. My testing is just for technical evaluation and learning (so also no high volume), so no specific use case. Having said this, I see a lot of added value and demand at several projects. I am very sure the AHA effect will show up quickly in these projects.

We also have a driver for OPC UA where there exist multiple free tools. But, yes, the basic idea is to map all those proprietary protocols to a nice JDBC Like interface, so the most “AHA” you get out of using it against a real one. If you could / would elaborate a bit about your use cases or your ideas you can of course ask Chris for an access to the codecentric IoT Lab and test against real PLCs via remote.

But from your response I understand that you need one to use PLC4X even for Hello World examples. I assume there is no "free / open test generator" as all of these protocols are proprietary and not using any standards (this is the main motivation for the PLC4X project). I saw FactoryIO (https://factoryio.com/editions/) in one of the PLC4X videos on Youtube. I could use it and its S7 emulator for a hello world with the 30 day trial. Is this the best / easiest option if you don't have any hardware?

The hello plc4x example is made for connecting to a Siemens S7 device, I think. So you can give it a IP and a field address of a Siemens S7 plc and it will fetch the results. Regarding the demo driver...i have to check (when by daughter finally decides to sleep... :) and respond then back to you.

I wasn't aware you can use more than one profile. I can confirm that the built now works and generates the JARs. Can you also point me to some documentation or example how to send some hello world messages using a hello world driver? I assume I have to use DummyDriver somehow? ⇒ java -cp /Users/kai.waehner/git-projects/plc4x/plc4j/examples/hello-world-plc4x/target/plc4j-hello-world-plc4x-0.5.0-SNAPSHOT-jar-with-dependencies.jar org.apache.plc4x.java.examples.helloplc4x.HelloPlc4x Missing required options: connection-string, field-addresses usage: HelloPlc4x --connection-string <arg> Connection String --field-addresses <arg> Field Addresses (Space separated). Looks like there is no complete getting started example available somewhere? After I have it running, I am happy to write a more detailed summary and create a PR for the readme file.

So you would need to add "-Pwith-java" to the mvn cl string.

Thank you. Best regards, Kai Waehner
