TIA Single Pair Ethernet Consortium’s Post

Transcript

Thank you very much, Bob. I never know what people are going to say about me. I've been at this a while and I've been at single pair Ethernet for a while and I'll tell you. The room here is full of folks who are thinking building and process automation. But I'm going to talk about SBE in in in a much more general sense because those questions cross my desk all the time. Before I get into that, though, I gotta take care of just a little bit of business. As you notice, I hold a number of positions in, in, in I triple E, and they want me to make clear whenever I give a talk that's it's going to be public that my opinions that I'm presenting are my own. Consider yourself warned. These are not formal positions of anybody else. I don't think they're going to be terribly controversial. One of the questions that crosses my desk a lot. Really. What do you mean by SP ESP do this? Can SPE do that? Can I use it for this? Because they hear a lot of different things, so the unasked question. That actually shows up a lot. At the same time is what exactly is single pair Ethernet? It's a really general question. And you think, Gee, that's a simple one. I go count, go out, you know, and I look at the protocol on the wire and say, hey. These are not. OK, that's good. Then I look at the number of wires. Oh, look, there's only two of them. Well, that must be single pair Ethernet. And. Unfortunately, that's just way too general to be useful. Single pair Ethernet goes way back. It actually goes all the way back to to in in the 90s when people were delivering residential broadband access over a single pair of wires. It was Ethernet, it was single pair. It's what you call DSL. I did that back in the 90s right now. It's actually the only thing we don't need when we say single pair Ethernet, the fact is in I triple Lee in in today's modern single pair Ethernet that began about 2012 and it began with a push towards automotive Ethernet and the number of the parts that you actually see getting used. And a lot of the applications using are actually adaptation of technology that's developed for automotive being used in buildings, being used in factories, being used in other places. So when you see 100. Case T1 or some people might call that it 802.3 BW and you see the words poodle used and you'll you'll notice I will use the term in here your poodles power over daily. I'll use the term in here, SP OE or single payer PO E. Those are terms that came out of the automotive ecosystem and. And yet single pair Ethernet means that too. But to us here. And to our focus and most of our presenters today, it means 802.3 CG, which is a very recent project that was something that started around 2017. And finished in 2019, whereas the automotive stuff started back in 20. It contains industrial automation applications, building automation applications. Some intra system applications such as they're used in cars and actually the automotive industry was a participant in it two or three CG. It contains powering certain augmentations to what was the original power of data line that really made it more of a member that Poe family. And other groups such as the APL group, APL companies played a key role in defining 802.3 CG layered their own powering and their own set of configuration options on top of 82.3 CG. To make it really suitable in process control applications. And then one of the most confusing things that we're not going to talk about today is it within 802.3 CG there's actually. Two different files. And the second one is not point to point, it's what you call it. It's really a return of the basics for Ethernet. It's shared media. So I added 2.3 CG is interesting because for those of us in Ethernet, we've been wandering up to higher speeds and higher speeds and higher speeds and higher speeds. And while our the guys who do optical networks, we're talking about 204 hundred now 800 Gigabit Ethernet. In the automation world, industrial, where we're still taking a big, big jump up in speed, but we're going all the way back to 10 megabits. And 10 megabit Ethernet is, you know, go back to that DSL reference, 10 megabit Ethernet is back even earlier than that. It's, it's the late 80s, early 90s for the wired Ethernet world. And single pair Ethernet is going back and taking a hard look at those low rates. In industrial and automation environments. In particular, and doing it in a way that uses modern technology. But really it's all about applications because that's what drove it. Ethernet as a technology was developed to connect computers to computers. One of my friends, Jeff Thompson, who was really, really early Ethernet guy, one of the original Bob Metcalf team, if you will, will tell you that Ethernet was developed to connect up laser printers at Xerox Park. I don't think we're in this room to connect up laser printers primary. We're here because networking is everywhere. Every pair of wires have seen has the capability to carry power and data. Everyone is interested in connecting up sensors. If I look around this room here, I see lights. I see fire sensors, I see sprinklers, I see exit signs. I see more firearms than I could pull. All of these things have wires to them. And every one of those wires has a need to carry data, and most everyone of them has a need to have power on it. So single pair Ethernet is about applications that require power and data. Yes, it began in automotive, but today we're focused on building automation, industrial process control automation. And quite frankly. Any application you can dream of because. Every time I turn around. I get questions about new applications and they all are related to this notion of power and data. So first a moment about power and data. What I think got us into this, and again, you know my opinion, right, What got us into this was actually the PO explosion when when Ethernet added power originally we did it for phones. But you know, the nice thing about Ethernet is that. You write a standard and you think about it as an application. You may even have descriptive language in the standard that talks about using it for automotive or this or that or the other thing. The standard doesn't restrict what you can use it for. It may tell you that, hey, it was designed with this in mind, but people get to come up with whatever they want to. And when Poe came about, it was done for phones. And pretty quickly people figured out that it was also good for wireless access points, that there was generally no power output. And then they would tell us that they would tell us, they would realize that there were plenty of things that were often. Power output for security cameras. I got a bunch of them in my house and any power outlets by them. No, I run Poe to them. That's really common. You know when when Ethernet Alliance started running a PO E certification program? This is multiplayer stuff. Every time we turned around and we were trying to write the trademark application. What is it? What do you find PEN? We found the new thing. Anything you couldn't find POV on that we found dog collars with Poe in? Now, we're not here to talk about cars today, but Poe has become ubiquitous. It's become ubiquitous for just general applications. So when we came to doing Ethernet on a single payer for automation applications, we knew power was key. And originally this was power in in automotive environment and they just called it power over dateline unfortunately for us maybe. This very very generic statement which could mean almost anything. It just means data and power. Has a cute name. It gets pronounced like dogs. It's poodle. Umm. And also unfortunately for it, just fundamentally on a single pair, you've got some key differences from how you did PO. And the key differences are deep in the technology and we're going to hear talks today about how to build and how to design products with SBE. We're Here talks about power over data line. Fundamentally, it's a little more challenging because you can't put the power across 2 pairs in a way that is sort of out of band to the data. You have to put it on same wires, the data. And that means you end up having to have some kind of filtering apparatus to to take the power that's at DC and separate it from the high frequency stuff that is the data. It's different, but it's also the same. It's cold power. It's safe power. It does. It does what we call in the NEC but you know, under the Class 2 envelopes. And it's well described. You're going to hear more about it later, but if you want, there's a reference on this slide here where there's actually pretty good tutorial on the earliest versions of. The power over data line or SP OE technology. But back to the applications. Because I say that 82.3 CG started in process control and the APL group was, was huge in getting this going. Some of the sponsors of this group were, were key members and key contributors to the 802.3 DCG group. They're using it in some fairly straightforward and specific ways. They set up fields switches. They go out over a large plant. That's where the kilometer came from. The power goes from field switch to sweet field switch. It's very regulated because they have a process. Environment. It's so regulated, in fact, that that environment. Differentiates itself on how the power is delivered. The AP you'll hear Ethernet APL and then sometimes you'll hear ten base T1L. Ethernet APL users 10 based oncologist uses its own powering spec in there that's more suited to that environment. You'll hear more about that later, but ten base T1L? And the single payer Power over Ethernet is used. All kinds of other places I get a lot of interest from folks saying can I use that for security? Hey, my camera is more than 100 meters away. Sure you can. And we've got people who are showing products for that today. Can I use it for building controls or sensors? Sure I can. Can I use it for HVAC control and monitor? Sure I can. Anything you can connect with data fire systems you know class and or type end type of systems in in the NEC. Sure, you can use that. Elevators can use it. And it's all fueled by connectivity, what we usually call IoT, which, by the way, is one of my least favorite terms because it means everything to everyone. But it's also fueled by wireless. People think, ohh, how all this is going to be wireless. Well, no, actually, because The thing is. You got a million sensors in a building, Go, go, go, change a million batteries. So you're going to have a set. Of things that are wired. And instead of things that are wireless and you're going to see just like in the in the regular land space, they fuel each other and they they fuel each other for a great connected group and it's all driven. By the ease of use, the interoperability, the power. That is Ethernet. So I'll leave you with the thought here and say, how do you make sense of all this? I make sense of this kind of stuff because. Not as you know, what's the standard number that's sort of, that's sort of, you know, once you've already, once you've already zeroed in on what you want, that's where you go look, I make sense of it in terms of application spaces. And I think a single pair Ethernet is something that's sort of began. In automotive and really quickly move to include intra system links. If you look at 10 base T1S that was in 82.3 CG, it's actually taking off more in the intra system industrial automation space. Then moved into building automation and industrial Ethernet. You're seeing today an explosion of products. They are rolling out today and there's a number of them in in the next room here. You're going to hear about a number of them today. You can hear about how to how to make that explosion bigger. That chain reaction is happening. And while it's happening, just rest assured, the industry isn't isn't waiting. The industry knows that it takes five years to do this. They're feeding the same kind of explosion that went from 10 megabit Ethernet to fast Ethernet to Gigabit Ethernet in the 90s and IT. And doing for building and process automation today. What was done in the 90s for computer networking? And with that. Looking forward to an exciting day and exciting next few years. Thank.
