I've tried your method and it work when I run on my visual studio. The OPC UA client able to read and write the tag. But when I created setup files and installed on PC. it show Certificate errors. did I missed anything? Can I use visual studio setup for deployment on OPC UA setup?
Rarely do I see someone have such a deep knowledge of his field while also being able to communicate it in a nice and easy to understand way. Very good content, thanks a lot for your work! Greetings from Hungary!
Typically with a client and server using OPC DA, you have to have a local account and password on both machines(workgroup environment) for the machines to authenticate with one another. How does this work with UA and authentication? Do you still have to have this?
This is pretty nice video series. Thanks for making all this. I have a question. With my quick google search, I see OPC UA most used on Windows platforms therefore .NET languages are mostly used. However, I am looking for OPC UA Web Platform is a web application based on other then .NET languages, like python, golang etc for a linux application. Can you point me a good starting point for that? Huge thanks!
Hi, thanks for the great videos. I'm new, and just confused with the rules of naming the tags in XML. Do you have any recommended books or study materials for that?
Another great video Kudzai. Question: Have you ever come across a live implementation of a local discovery server? Or have you come across any vendors that supply such a server?
Thank you, Emile. The most prominent LDS, as far as I know, is the executable provided by the OPC foundation itself opcfoundation.org/developer-tools/samples-and-tools-unified-architecture/local-discovery-server-lds/ I understand companies such as Softing redistribute it with their OPC UA software products. There is also a NodeJS version from one from www.npmjs.com/package/node-opcua-local-discovery-server However, I have never installed or used any of the above. The closest implementation of OPC UA Discovery that I'm familiar with is Azure IIoT reference architecture's OPC Twin module. But I can't say for certain if this one is as per OPC UA spec or it uses some special mechanism for OPC UA discovery.
