Shawn Tierney (Host): Hey, everybody. Happy lunchtime. It is Shawn Tierney here from Insights and Automation. I’m actually back in the training room working on a bunch of different stuff, but, I did wanna jump on here at lunchtime. Actually, I have to, be in another meeting at 01:00, but still, I wanted to stop by and do a automation tech talk with you at lunchtime.

And, I was just thinking of something, like, I just learned. Well, I shouldn’t say I just learned it. But, in any case, guys, feel free to post any comments, questions, or in the in the chat. I don’t see the names when you post them on LinkedIn. I don’t know why this is a StreamYard limitation, but I should see your username if you post them from YouTube.

And, of course, afterwards, I do post these on the automation blog. I post them on the podcast channel, and I try to do the, the, the text version of the show afterwards when it’s ready. So So if you wanna read it the following morning or later that night, you can. So with that, in any case, I hope you’re having a great lunch. Today, I wanted to talk about a couple things here first.

The first one is if you’re in any of my courses, I wanted to talk to you about I’m adding a bunch of new lessons every day as I work on the new ones, the new courses, which you all don’t have access to yet, but you will get access to them, you know, and the appropriate ones. I updated the IO devices, lessons. So and I actually have all the updated IO here and addressing and whatnot. So I just wanted to make you guys aware of that. I’m doing that for all of the existing PLC courses.

I’m updating them all. Also, I have stop files coming too, updated stop files. So, keep your keep your eyes out for that. But now let’s get into today’s topic, and it’s about the series c chassis, the 1756 ControlLogix series c’s chassis. Let me go back to full screen here.

So recently, I’m I’m setting up a, an alternative, a filming studio in the house. Right? So if, you know, if we have a bad winter and I get snowed in, I wanna be able to film. Right? And so what I have had up to this date is, and, again, all these were purchased us on the secondhand market because of the expense of the new trying to keep my courses affordable.

But this is a series b seventeen fifty six chassis. I’m I’m sure most of you have seen these before, and this is actually getting mounted in this room. And I don’t know how good this webcam is. I don’t know if you guys will be able to see that label. I haven’t I didn’t try that before the show.

Everything on my screen is reversed, but that is definitely a series b. And I just wanna look at these patterns here. Right? Now one of the things that you may have noticed with newer products from Rockwell, and we’ve had them on the show that cover this stuff, and I hope to have them on the show many more times this year too. But in any case, I I love having all vendors on the show.

I think I was telling you guys early in the week. I met with, local, integrator who carries a lot of the brands that I have not had on the show, and I wanna get those people on the show. So they’re gonna they’re gonna I’m sorry. I should say a local reseller and panel shop, and they should, they’re gonna try to hook me up with them. So great guys over there, Chris and Amy.

But in any case, I wanted to, you know, when when we came out to the new modules like this guy, you could see they now have this huge I hope you guys can see this okay. Huge heat sink on them, and there’s a warning even on the, like, the LA. I don’t have an LA, but there’s actually a warning here. You can you probably can’t read it from there. But it’s like, hey.

This thing could be hot. So when you take it out, be careful. And they feel a lot heavier. If you compare this to, like, an l seven right? So here’s my safety l seven.

The partner’s still in the chassis. But look at that. You can you can see right through that. K? Not as beefy.

Right? It’s still a very powerful controller, but when you compare it to this guy, the heft of that that, heat sink And the l eights, I think, are even hell heavier than this. I don’t know about the l nines. I I hope to get my hands on one, in the near future, but, you know, they’re not even out yet. So I don’t wanna put myself too far ahead.

But in any case, you know, when when Rocco was releasing new chassis, they decided to increase the venting. So, again, just for comparison, here is the series b chassis. Okay? Right. And let’s see if I can hold these both up.

I haven’t practiced this. I it’s just lunchtime. And, look at the series c chassis. So I picked this up from my home studio. I had to drop a $110 on it, but, hey.

You know, now that I got it, I got it. Right? Look at the difference of the amount of airflow you can get through that baby. Okay? And now they say and I I you know, I didn’t test it.

I’m not consumer reports. I don’t have heat cycling ovens and all kinds of strain gauges and stuff that, you know, I could test this, but they say it’s just as strong as the other one. Right? I gotta be careful not to break it. I don’t wanna have to buy another one.

But, in any case, it’s a lot more venting. Right? And it makes sense because these newer products generate a lot more heat because it’s just the chipsets are in there. Now I thought it’d be fun, though, to let’s let’s see what Rockwell officially says about these new chassis. So now we’ll go back over to the stage here, and, I am logged in.

This is a free I do not have a tech connect. I don’t, like, need all the tech support they offer. So I had one a long time ago, but I let it expire because, well, I’m self employed. But in any case, I haven’t needed to call them. So here, this is a tech note I found just right before coming on.

I just typed in ControlLogic series c’s chassis. Boom. Came right up. I I love the simplicity of their and the ease of use of their knowledge base. I really do.

But in any case many companies have good knowledge bases. Those who don’t should look at the people who do because it it does make a difference from the user perspective. In any case, they say, hey. Series c, direct replacement for series b, and then they have a nice little story in here. So the difference is the ventilation, alright, the knockout pattern in the sheet metal for the convection airflow.

While the design team was making the sheet metal changes, they took the opportunity to incorporate a few other mechanical and physical enhancements, that have been received in the past. Improve card guide. Now I haven’t compared the two, but I can tell you sometimes those old chassis, the the guides were sticky, and it was very annoying because you’re spending a lot of money for something you want that card to slide in and out. New additional optional mounting hole for high shock vibrate slash vibration environments. That’s always good.

Improved ventilation for future high performance modules. I think somebody at Rocco told me they were getting to the point where you’re gonna have to start derating. These things were generating so much heat. They would have to start derating the you know, you know, a lot of companies do 20, you know, zero to 50 c or zero to 60 c without getting into the extreme products. So, but, yeah, they with with the they needed more airflow to avoid that derating.

So saying, hey. You only can go to 40 c or whatnot. What else do they have here? Improved stiffer mounting tab. I don’t know, I don’t know what what we’re talking about here.

The plastic seem the same. Maybe it’s the, maybe it’s the, the ears, the mounting ears here. I don’t know if they feel stiffer. Just trying it out now. Trying it out live.

They they feel the same. So I don’t know. I don’t know what I don’t know what that is. Because if somebody from Rock was wanting watching and you wanna join, join, let me know. New additional grounding screwed.

Is there a another grounding screw? Oh, yeah. There’s two now. Let me go back to full screen here. I didn’t notice that.

Full screen. Okay. So there is now two. I don’t know if this is coming out well on the camera. One, two.

Whereas before, there was only just the one. So, you know, two’s better than one. I mean, I I don’t know what that cost them to do that, but I’m thinking probably less than a buck of chassis when I don’t know. They sell for a lot new. I mean so you think that if people want it, give it to them.

Okay. So let’s go back to here. Please note, the series c’s chassis will carry all the same certifications as series b. Temper temperature ratings improved from zero to 60 to minus 25 to 60. You wonder I I I don’t wanna think the additional airflow would allow you to go cooler.

Right? Maybe I’m wrong. Maybe the additional the additional, no. It has to be something else. I don’t know.

You guys tell me. What do you think? Why can it go cooler now? Nonoperational shock will decrease from 50 g from 50 g to 30 g. Interesting.

Interesting changes. So, yeah, that’s it. Let’s see what techno this was. This was QA twenty three six eighty five. And so that is what I learned new today.

Actually, I knew about this back. I think it it happened back in 2015. And, you know, I think the the cool thing was that, you know, they told us ahead of time, it’s a 100% direct replacement except for this the the storage fee, I guess. But, I just wanted to share that with you because I finally got one in for the, for the home studio for those snow days or any other days that, you know, the car breaks down, or something else, I can still film out there at the home studio. So I’ve take actually taken a couple of the cameras out of Studio A, which I’m just using Studio B now, and, and bringing those home as well.

So, in any case, so that’s what I had. Now I’m looking over at the chat here. I want I wanna thank everybody who joined, by the way, and who watched. I’m not seeing anybody in the chat. So I think with that, what do we got coming?

Last yesterday, we had the PROFINA episode. I edited it yesterday. You know, I have you have to watch it a couple more times to edit it, and I really thought it was good. I really enjoyed it. They do have free seminars coming up, so keep that in mind.

Also, free IO Link seminars coming up, and the the episode I’m recording this afternoon is on IO Link. So pretty excited about that. Very popular product. I can’t wait to add some IO Link lessons to my courses, but, you know, everything has to everything comes in its own time. But I do have plenty of IO Link products here, and I have some IO Link shows coming out as well.

But with no questions, I think I’m gonna go get ready for my meeting. I wanna wish you guys all good health and happiness. I think tomorrow, I’m going to release, my interview with Giovanni for the lunchtime, show. So it’s about a thirty minute inter interview, and I had a lot of fun talking to Giovanni. And, again, if any of you wanna come on the show and hang out with me for a half an hour or forty five minutes during lunchtime, just get into contact with me.

But I’m gonna keep today’s show a little bit shorter because I have to run to another meeting. But with that, I wanna wish you all good health and happiness again. Until next time, my friends. Peace.
