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!

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.

Thanks for the comment!

[@eragonritter6436]

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.

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

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. 👍

[@4.0Solutions]

Glad it was helpful!

[@smukerji7065]

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.

Very good historical background guys. More power to you

[@ShannonLooper]

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.

[@4.0Solutions]

Thank you, Shannon! Totally agree!

[@KwizzleHazzizle]

I did not even know that OPC UA was intended as an IOT protocol by the OPC foundation. I always used it between PLC and SCADA layers.

[@4.0Solutions]

No, but the foundation seems to want you to think that. Or rather that it's good for collecting data for integrated/shared IT-OT information uses.

[@DuneKraftwerk]

Starts from the real beginning : DDE

[@ofc2463]

Thank you so much for this amazing video. I am struggling with some fundamental. Is the main idea for OPC-UA is data collection or is also for real time control. e.g. controlling a motor , synchronization between industrial controllers, turning on/off actuators, etc ? I mean is it a replacement to existing protocols as Ethernet/IP, Modbus,etc ?

[@adamrohde3513]

No it isn't for real-time control. Generally OPC goes 'up' from the PLC to an HMI or SCADA system, not 'down' from the PLC to your field devices like sensors and actuators. OPCUA and EtherNET/IP are apples and oranges. ETHERNET/IP and EtherCAT for example are more apples and apples. Modbus...I don't know exactly but I think its like a turkey

Hi from ZMS Technology Germany

[@4.0Solutions]

Welcome to the Industry 4.0 Community! ♥️

[@promiseenyinnaya6346]

Please to be clear, does OPC mean Open Platform Communication or OLE for Process Control. Because these variations slightly confuse me. Another thing i want to say is, the OPC foundation are just making more money from manifacturers and organizations. Before i watched this video, i thought it was an open communication protocol that could allow all industrial devices to communicate with each other. But now i see it's only if you belong that you have the chances (likely, only if your devices use the same part of the standard) of communicating. Crazy how the world works, so crazy

[@4.0Solutions]

OPC in OPC Foundation originally stood for OLE for Process Control. OLE refers to Object Linking and Embedding, a Microsoft technology for inter-process communication. Over time, OPC has evolved beyond its original meaning and now represents a suite of standards for exchange of data in industrial automation and other industries.

[@chickenz4604]

nice

[@4.0Solutions]

Thanks!

[@sherylmccrary9045]

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

[@4.0Solutions]

🤔

[@HalenRodrigues]

Does reasons 1 and 2 for OPC-UA not been the future of automation still valid since OPC-UA PA-DIM and OPC-UA FX companion specs release?

[@jaythompson5102]

Walker .. god damn you are a great presenter. I am new to OPC UA, am I wasting my time learning it and should I go learn SQL and MQTT?

[@4.0Solutions]

Jay -- thank you. I recommend you learn all three. In our mentorship program at iiot.university, we have all of the mentees learn SQL, Python and Ignition MQTT and OPC-UA during step 1. Its hard to get the complete picture of Industrial communications and IT/OT convergence without them all. Blessings to you.

follow you in several you tube`s,one question:mqtt can be used instead of iec61850 (goose),excuse me ,this is not the way for discuss this topic,thanks in advance
