 Shawn discusses how many so called “experts” don’t use the correct terminology when referring to Rockwell and Siemens Modules in today’s episode of #AutomationTechTalk Lunchtime Edition livestream: Watch Automation Tech Talk on The Automation Blog: Listen to Automation Tech Talk on The Automation Blog: Automation Tech Talk Show Notes: Thanks for listening!

It’s Sean Tierney here from Insights and Automation. And I’m trying something completely new. I hope it’s working. I hope you can hear me. I’m actually in a different room here. What I’m calling studio C, which as I’m updating all my PLC courses, I need to I needed another spot to be able to, um, film videos. And so I’m kind of looking off to the side because I need to get another monitor in here. But in any case, I hope you’re doing well. I don’t know if you guys are seeing my audio. I don’t know if you’re hearing my audio or seeing my video. I don’t know what the quality is, but hey, you get to try things out. I’m actually trying Restream instead of StreamYard because there’s some audio delays with the StreamYard that, uh, if you’re not using the webcams, audio or whatever. So in any case, I just figured I’d just, uh, show you, uh, you know, test this out. And I wanted to talk to you about discrete versus digital. I o so I’ve seen some people who call themselves experts. Of course, you guys know I train for a living. I teach, uh, you know, Allen-bradley, Siemens PLC, HMI and SCADA and, uh, you know, there’s a lot of competition out there, a lot of people saying they’re experts and a lot of them actually share incorrect information. And one of the not so, not so horrible information is shares when they’re calling Rockwell’s IO discrete IO. And of course, if you want to use the word discrete, fine. Right. I always use the word digital. And I’ll show you why I use that word. And I know even in Rockwell, there was controversy years ago, I remember seeing a, uh, a letter come out from Rockwell. I don’t know if it was rescinded or not, saying we’re going to go from one to the other or whatever, but in any case, it kind of came to mind. Uh, I was reminded of this. Let me go to my my screen here, but I recently, uh, partnered with Schneider Electric, uh, great company to cover their modicon edge. Io wants a new a whole bunch of io they came out with, and I think it’s really cool. I filmed, I think, a forty five or fifty minute, uh, episode on it. They’re reviewing it now Ensure there’s no additional graphics they want to add or anything I technically got wrong. That’s one of the things we do with our sponsors, is they can go through and say, did you cut this? Add this. You know, just just we want to make sure it’s technically correct. They don’t they don’t get the storyboard, a script, the the episode. But in any case, it was a lot of fun doing that episode. It’s again, it’s not ready to go out yet, but soon. Uh, in any case, um, I noticed I kept saying digital I o and their modules specifically say on them discrete I o. And so, um, I just noticed that the restream is putting their logo right over my face. Isn’t that nice? So let me take care. See, this is what we call about testing things. You get to test things out. And I have a very easy fix for that. No, that’s not what I wanted to do. Thank you. All right, we’ll put that over there. Okay. That solves that problem. So in any case, um, you know, and I so I’m recording the video. I keep saying digital I o and then I’m opening the boxes and they see discrete and I’m like, oh that’s, that’s very interesting. It’s a different um, they use a different name for that. And I’m like, you know, I’m curious, you know, I’m saying digital I o because it’s a Rockwell thing, right? I’m like, I’m curious, what does Siemens call their I oh, now they call their I o modules. Signal modules. Right. Which is a slight difference. So I brought up the online uh tool here with Siemens. I said let’s see. And it’s digital modules digital and analog modules. Right. So you have digital and digital digital in out. Right. I’m like okay. So Siemens is using the word uh digital instead of discrete like Rockwell. And uh, but but Schneider is using discrete and not that it’s a big deal. Again, I’m doing this part as a, you know, tongue in cheek picking on some of my competition or uses the wrong terminology with the wrong brands, but also just to test out. And we already found some some mistakes already, but with the Restream. But in any case, before buying Restream, I want to test it out to make sure it does what I want it to do. So in any case. ...
