What is OPC? - Part I - What you need to know...

In this video, Walker Reynolds gives a 10,000-foot overview of OPC and its history. He also shares 3 things you absolutely need to know about OPC & OPC-UA when architecting Industry 4.0 Solutions. Thank you EMQ for sponsoring this video.

In my Udemy course on Classic OPC, one of the demonstrations involves a client that supports HDA but a server that does not. It is used to advise the viewer to ensure that they check which of the DA, HDA, A&E specs the clients and servers support in order to avoid a "mismatch". Whilst this is a relatively easy thing to check for in Classic OPC, it's not as easy in OPC UA as UA has many more considerations. I really appreciate how you gave a view into the structure of the OPC Foundation. I never knew it was structured like that but it clears up a lot. That being said, I think Classic OPC was an amazing thing in the 90's. It lead to so many benefits. But you are quite correct about the trajectory. Something went a little awry. Thanks once again for this contribution!

One of the best youtube channels/videos I have ever seen on my youtube watching history. Keep up the good work !

[endingofworldmovies]

damn, thanks man.
i have been working in a Iiot project in my company as a cloud support team and never really understood why they use kepware server and what is the drawback of opc ua and all, this video is such a gem of information's
thanks for creating and contributing to this channel love from India.

This is pure gold! Can't wait for part 2!

[michaeldowdell]

Great content. I would really appreciate getting rid of the backgroung music.

In the 90's when I was working for the steel industry automation, we had an open and modular communication system known as Oracle Remote Data Transfer to interoperate Simatic PLCs with supervisory control systems. Cant find it any longer.

This channel is truly great. It is Straightforward to the important part!

[erickcruz]

Great great content, I always learn with your videos, this OPC series is exciting. Greetings from Cuba

[eragonritter]

What about Apache PLC4X in comparision? As the project aims to do exactly that but Opensource? Especially their Mspec format makes these protocols really readible for everyone.

[vadimkoller]

Great content guys, I’m really excited about this new OPC series

[dysenkennedy]

Thanks, good explanation! A bit over edited, less jump cuts would make it easier to watch imo

[MartinBoers]

That's an interesting looking PLC on the table next to the white board. ;-)

[sherylmccrary]

So a spec originally intended to improve interoperability now proliferates confusion.

[dwsantx]

Thank you for a great intro to OPC UA. General discussion on overall architecture helped to grasp concept, general example for applications and compare/contrast to see why there is a discrepancy on its role in IIOT. 👍

[tommyhuffman]

This is exactly what I needed. Thank you, good sir!

OMG Last time I set up a network OPC connection was in the late 90s. I'm trying to set up one where the client box is a new VM and the server only had local connections. I forgot about DCOM. I can't believe there isn't a quick tool by now to configure DCOM. This is nuts.

[clayman]

Keep up the good work! Really interested in OPC ua protocol and it’s integration into different systems

11:40 The OPC Foundation definitely needs a UI/UX designer for creating a stunning front-end web design lol.

[MarcosDemian]

I absolutely loved the explanation. Very detailed and with some bits of humor here and there
