Shawn Tierney (Host): Welcome back to the automation podcast. My name is Shawn Tierney from Insights and Automation, and I wanna thank you for tuning back in this week. Now on this show, I actually had the opportunity to sit down with Thomas Weingoner from PI to learn all about PROFINET. I actually reached out to him because I had some product vendors who wanted me to cover their s two features in their products, and I thought it would be first it’d be better to actually sit down and get a refresh on what s two is. It’s been five years since we’ve had a PROFINET expert on, so I figured now would be a good time before we start getting into how those features are used in different products.

So with that said, I also wanna mention that Siemens has sponsored the episode, so it will be completely ad free. I love it when vendor sponsor the shows. Not only do we get the breakeven on the show itself, we also get to release it ad free and make the video free as well. So thank you, Siemens. If you see anybody from Siemens, thank them for sponsoring the Automation Podcast.

As a matter of fact, thank any vendor who’s ever sponsored any of our shows. We really appreciate them. One final PSA that I wanna throw out there is that, speaking like I talked about this yesterday on my show, Automation Tech Talk, As we’ve seen with the Ethernet POCs we’re talking about, a lot of micro POCs that were $250 ten years ago are now $400. Right? That’s a lot of inflation, right, for various reasons.

Right? And so one of the things I did this summer is I took a look at my P and L, my pros profit and loss statements, and I just can’t hold my prices where they are and be profitable. Right? So if I’m not breaking even, the company goes out of business, and we’ll have no more episodes of the show. So how does this affect you?

If you are a student over at the automation school, you have until mid September to do any upgrades or purchase any, courses at the 2020 prices. Alright? So I I don’t wanna raise the prices. I’ve tried as long as I can, but at some point, you have to give in to what the prices are that your vendors are charging you, and you have to raise the prices. So, all my courses are buy one, sell them forever, so this does not affect anybody who’s enrolled in a course.

Actually, all of you folks rolled in my PLC courses, I see it updates every week now. So and those who get the ultimate bundles, you’re seeing new lessons added to the new courses because you get that preorder access plus some additional stuff. So in any case but, again, I wanna reiterate, if you’re a vendor who has an old balance or if you are a student who wants to buy a new course, please, make your plans in the next couple of weeks because in mid September, I do have to raise the prices. So I just wanna throw that PSA out there. I know a lot of people don’t get to the end of the show.

That’s what I wanted to do at the beginning. So with that said, let’s jump right into this week’s podcast and learn all about Profinet. I wanna welcome to the show, Tom from Profibus, Profinet North America. Tom, I really wanna just thank you for coming on the show. I reached out to you to ask about ask you to come on to to talk to us about this topic.

But before we jump in, could you, first tell the audience a little bit about yourself?

Tom Weingartner (PI): Yeah. Sure. Absolutely, Shawn. I’m gonna jump to the next slide then and and let everyone know. As Shawn said, my name is Tom, Tom Weingartner, and I am the technical marketing director at PI North America.

I have a fairly broad set of experiences ranging from ASIC hardware and software design, and and then I’ve moved into things like, avionic systems design. But it seemed like no no matter what I was working on, it it always centered around communication and control. That’s actually how I got into industrial Ethernet, and I branched out into, you know, from protocols like MIL standard fifteen fifty three and and airing four twenty nine to other serial based protocols like PROFIBUS and MODBUS. And, of course, that naturally led to PROFINET and the other Ethernet based protocols. I I also spent quite a few years developing time sensitive networking solutions.

But now I focus specifically on PROFINET and its related technologies. And so with that, I will jump into the the presentation here. And and, now that you know a little bit about me, let let me tell you a little bit about our organization. We are PROFIBUS and PROFINET International or PI for short. We are the global organization that created PROFIBUS and PROFINET, and we continue to maintain and promote these open communication standards.

The organization started back in 1989 with PROFIBUS, followed by PROFINET in the early two thousands. Next came IO Link, a communication technology for the last meter, and that was followed by OmLux, a communication technology for wireless location tracking. And now, most recently, MTP or module type package. And this is a communication technology for easier, more flexible integration of process automation equipment. Now we have grown worldwide to 24 regional PI associations, 57 competent centers, eight test labs, and 31 training centers.

It’s important to remember that we are a global organization because if you’re a global manufacturer, chances are there’s PROFINET support in the country in which you’re located, and you can get that support in the country’s native language. In the, lower right part of the slide here, we are showing our technologies under the PI umbrella. And I really wanted to point out that these, these technologies all the technologies within PI umbrella are supported by a set of working groups. And these working groups are made up of participants from member companies, and they are the ones that actually create and update the various standards and specifications. Also, any of these working groups are open to any member company.

So, PI North America is one of the 24 regional PI associations, and we were founded in 1994. We are a nonprofit member supported organization where we think globally and act locally. So here in North America, we are supported by our local competence centers, training centers, and test labs. And and competence centers, provide technical support for things like protocol, interoperability, and installation type questions. Training centers provide educational services for things like training courses and hands on lab work.

And test labs are, well, just that. They are labs that provide testing services and device certification. So any member company can be any combination of these three. You can see here if you’re looking at the slide, that the Profi interface center is all three, where we have JCOM Automation is both a competent center and a training center. And here in North in North America, we are pleased to have HMS as a training center and Phoenix Contact also as a competent center.

Now one thing I would like to point out to everyone is that what you should be aware of is that every PROFINET, device must be certified. So if you make a PROFINET device, you need to go to a test lab to get it certified. And here in North America, you certify devices at the PROFINETERFACE center. So I think it’s important to begin our discussion today by talking about the impact digital transformation has had on factory networks. There has been an explosion of devices in manufacturing facilities, and it’s not uncommon for car manufacturers to have over 50,000 Ethernet nodes in just one of their factories.

Large production cells can have over a thousand Ethernet nodes in them. But the point is is that all of these nodes increase the amount of traffic automation devices must handle. It’s not unrealistic for a device to have to deal with over 2,000 messages while it’s operating, while it’s trying to do its job. And emerging technologies like automated guided vehicles add a level of dynamics to the network architecture because they’re constantly entering and leaving various production cells located in different areas of the factory. And, of course, as these factories become more and more flexible, networks must support adding and removing devices while the factory is operating.

And so in response to this digital transformation, we have gone from rigid hierarchical systems using field b
