No, I don't have a PLC. 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?
