Hello Alexis,
Welcome on mailing list, and thank you for interest in PLC4X! Sorry for delayed answer, you found me (us?) during Easter break.

In terms of URI - the protocol prefix you use is "opc" flavor. Due to internal library architecture we do not follow OPC specs for connection string, at least in this part. Please have a try with "opcua:tcp://...", it should work. Also note that http transport/xml encoding is unsupported. We cover only binary marshaling.

Kind regards,
Łukasz

Hi,

Thanks for this great piece of software. However, I am having trouble
connecting to opc server (opc.tcp://
uademo.prosysopc.com:53530/OPCUA/SimulationServer) freely accessible on the
internet. On connection I receive an exception "unsupported transport tcp".

Your help is appreciated, we intend to use plc4j driver in our projects
soon. Thanks in advance for your cooperation.

Regards,
Alexis
