Wrapping my head around OPC UA - Part 1

When I am researching a new standard to do with industrial network communication, I like to dive in and immerse myself into all of the details of the standard. After that, I try to see what I can build with it. After all, my goal is not to write a white paper about it, but rather to use it practically to solve problems. But OPC UA poses a challenge in this regard. The specification is enormous, and there are a lot of options, and quite a bit of it is not implemented in any real world practical software applications.

So in learning OPC UA, I have decided to approach it differently by asking this question ... "What is it that I need to know about  OPC UA to use it in the building practical real world commercial automation applications?". So I want to understand the theory and parts of the spec in so far that it will allow me to use OPC UA software to build systems, as opposed to writing some esoteric white paper on it.

So I am going to start that process in this video and continue posting more videos over the next couple weeks to answer my question. I am going to be learning about OPC UA by creating these videos on it. Please feel free to comment on the videos and add your knowledge as it would help in my overall understanding of OPC UA.

I always learn something from you. Thank you so much for coming back.
Waiting for more informative videos.

Great intro, Emile. I'll certainly be following your journey to learn more about OPC UA.

Thanks for contributing and helping us. do you have any course on IEC104/IEC61850 coming up?

Hi Emile thank you for this video. I am new to OPC UA. I am struggling with a fundamental question. Is OPCUA a replacement to existing industrial protocol like Modbus, EthernetIP? or is it just for data collection and not a replacement to protocol like. Modbus/EIP that are used for real time control for industrial equipments(like motors). Thank you

i have a question tho what do you mean with native protocol that link the device (sensor for example ) to a server ( plc i suppose ) is it profinet ? io link ? is that what you mean ?
