We’re going to use 2 IEC 61131-3 languages and a higher-level language called C++. The IEC 61131's five programming languages specified in the IEC 61131-3 Standard are Ladder Diagram, Instruction List, Function Block Diagram, Structured Text, and Sequential Function Chart. We are going to use Ladder Diagram and Function block in our exercise. Ladder Diagram was the first language developed for PLC programming. The simple explanation for why Ladder Diagram programming became so popular was that it closely resembled traditional “Relay Logic Diagrams”. Electricians and Engineers alike were familiar and comfortable with Relay Logic Diagrams and easily adapted to Ladder Diagrams. Early Ladder Diagram programming involved entering typical relay-type symbols onto a rung via hand-held programming devices connected to a PLC. It wasn’t long before computers and Graphical User Interfaces made this process much easier. This was all well and fine until more complex PLC hardware and I/O were developed and programming languages needed to advance thus spawning Function Block and other languages. Now we are at a point in history where there is an overlap between the activities of IT programmers and PLC programmers. More complex functions are not easily accomplished with traditional IEC 61131-3 languages and require higher-level languages such as C++ which is a familiar language in the world of IT programmers. For example, C++ programs can be easily created to produce “logged data” to assist with “Predictive Maintenance” (PdM). A program of that complexity cannot be easily created using Ladder Diagram. We want an LED to turn on when two normally-open pushbutton switches are operated. - The ladder diagram has 2 open contacts operated by SW1 and SW2 on the Starterkit. Operating the “coil” output will turn on LED1 on the digital output module. Operating SW1 and SW2 switches will close normally open contacts, energize the coil and cause LED1 to turn on. - Basic blocks of FBD are based on “Logic Operators” such as AND, OR, and NOT. The FBD to solve our problem is built around an AND Function Block. - Eclipse IDE can be used as C++ Editor. Because C++ is not an IEC 61131-3 language, it is not a programming choice available in PLCnext Engineer. With a few simple tools, a C++ project created in Eclipse can be imported into a PLCnext Engineer project. Physically there's no difference in operation between any of the 3 programs we used to solve our problem. What programming language should you use? There’s really no single correct answer as there isn’t one best PLC programming language. It’s apparent that we wouldn’t use C++ to solve the simple problem presented in this exercise as Ladder Diagram or Function Block are easier and more appropriate. Each language has its strengths and weaknesses and degrees of suitability for specific applications and of course, the challenge is to choose the correct one. @phoenixcontact1923 ============================= If you're just starting out in the world of PLC programming, you can upgrade your skillset with a free course on PLCnext from RealPars! https://learn.realpars.com/courses/plcnext-starterkit-configuration-and-programming-basics Starting with the basics and working up to programming in ladder logic or C++, you'll have a handle on this exciting new technology when it's all said and done. https://learn.realpars.com/courses/PLCnext-ladder-logic-course https://learn.realpars.com/courses/c-plus-plus-plcnext ============================= Get a RealPars pro membership: https://learn.realpars.com/bundles/pro ============================= Missed our most recent videos?

About YouTube Live View Counter
YouTube Live View Counter is the best way to check your Favorite Creator's Statistics updated in real-time! Data seen on Most Social Medias might be inacurate or delayed, that's why Livecounts.io came with idea for YouTube Live View Counter!
Everything is directly taken from official API Service provided by Social Networks. Every single count is updated every 2 seconds and is as accurate as possible.
To search for specific channel simply click "Change User" button below Follower Count Box, type your favorite creator's username and you're good to go! This IS NOT case-sensitive thus you type for example "MrBeast" or "MrBeAsT" and it should still work!
If you're interested in watching Follower Count battle then navigate to Compare Page below Follower Count Box or on Navigation Bar.
Thanks for using YouTube Live View Counter! If you have any idea to improve the website then feel free to get in touch with us it on our Twitter page.
The YouTube Live View Counter explained
What the YouTube Live View Counter does
The YouTube Live View Counter tracks the view count on a single video and refreshes it about every three seconds, the fastest cadence we run. When a big upload or a premiere goes live, YouTube's own view count updates in slow, lumpy jumps and freezes for stretches while it verifies views. This tool reads the public figure far more often, so you see the number climb in something close to real time.
Under the main view count you get three more live stats for the same video: likes, dislikes, and comments. The dislike figure is worth calling out. YouTube hid the public dislike count in 2021, and this counter brings back an estimate so you can still gauge how a video is landing, not just how many people opened it.
How to use it
Want the counter on a stream or a watch-party page? The embed option gives you a widget you can drop in. Want to race two videos, maybe a music video against its rival's? The compare tool puts both view counts side by side.
- 1Paste the video's URL, or search for it by title. A full YouTube link is the surest way to land on the exact video you mean.
- 2Confirm the right video from the results, since popular titles get copied and reuploaded constantly.
- 3Watch the view count climb. The likes, dislikes, and comments update alongside it, and the chart tracks the pace over time.
Why the count moves the way it does
View counting on YouTube is stricter than subscriber counting. YouTube checks that a view is a real person watching, not a bot or an accidental reload, which is why a brand-new video's count can stick at a suspiciously round number before it lurches forward. What you see here mirrors that. During a premiere or a viral spike the number races. Once the initial rush fades it settles into a steadier pace.
All of it is public. This is the same view count sitting on the video's page, pulled more often and shown without the delay YouTube adds when it is busy verifying. We do not inflate anything or add views. We just make the real number easier to watch as it changes.
Reading the chart
The chart under the counter plots every reading, so its slope is a live read on how fast the video is gaining views. A steep climb in the first hour is the sign of a video the algorithm is pushing hard. When the slope flattens, the initial rush is over. Turn on Advanced Metrics to add the total views gained since you opened the page and an average per-minute rate. That is the quickest way to tell a genuine breakout from a video that opened fast and then stalled.
The likes and comments moving in step with views tell you something too. A video gaining views but almost no likes is spreading without landing. Strong likes and comments alongside a climbing view count is the shape of a video people actually care about.
The moments people show up for
A new music video from a major artist is the classic case. Fans open the counter the second it drops to watch the first million, then the first ten million, roll in over the opening hours. Records get set and broken this way, and a live counter is the only place to feel the pace rather than read the recap.
The same goes for anything chasing a landmark. A video creeping toward a billion views pulls a crowd who want to catch the odometer flip. Creators use it too, watching how a fresh upload gathers views in its first hour to judge whether it is breaking out.
Common questions
Why does the count sometimes freeze? YouTube pauses public view counts while it verifies that new views are real, usually on fast-moving videos around round numbers. The counter reflects whatever YouTube is showing, so it freezes when YouTube does, then catches up in a jump.
Where does the dislike number come from? YouTube removed the public dislike count in 2021. The estimate here is built from the data that was public before the change plus ongoing signals, so treat it as a strong estimate rather than an exact figure. Likes and comments stay exact, because those are still public.
Does it work for any video, and is it free? Any public video works. Private, unlisted, or restricted videos that hide their stats cannot be tracked, because the numbers are not public. It is free, with no sign-up. Ads keep it running. Paste a video link and watch.
