Hi I have an issue with connecting raspberry pi to S7-1200. I followed the instructions line to line but at the end opcua client cannot connect. I have entered the node id, and server address correctly. Do you have any idea? I have attached payload messageIMG_20231106_041411.jpg

Thank you

What parameters you have used inside client node? None/None Anonymous or some other securityModel/securityPolicy?

Then it could be that you have to trust client certificate on S7-1200 => read Siemens manual.

Hi It was None/None Anonymous but I forgot to choose client certificate 1200 on hardware.

Thanks for your attention
