The Siemens LOGO! is a brilliant way to get started on PLC programming for small automation products in industry, school or at home. The basic models have eight inputs (up to four can be configured as analog inputs), four outputs, a 6 x 16 character LCD with programmable backlight color and a cursor keypad. This means that many applications can feature user settings without a separate HMI.
QuickPLC is pleased to provide a series of to-the-point tutorials on the PLC's instruction set and on the LOGO!Soft Comfort programming package.
An amazing set of videos produced, thank you for these. Would I be right in saying that for the Logo! Siemens PLC, which possesses 4 digital inputs that can be converted into 4 analogue inputs, the 4 analogue inputs can only receive 0-10 Volt signals but in order to use a 4-20mA input it would require the use of resistors to match 10V to 20mA? Would it be possible for you to make a video with 4-20mA & 0-20mA sensors being used and the signals converted in a demo circuit by an analogue amplifier on logo? Thank you!
Thank you for the positive comment. See if ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zewpKflxjqM.htmlsi=eXY8_sWaDRCGDnT1 answers your questions and let me know. You might also find ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VwrP_mM-KTg.htmlsi=EBFFUT8C1y7Mrwql of great interest.
Dear Sir, I much appreciate your tutorial. thank you very much for your teaching. this was really helpful for my knowledge improvement. if you can please do the new tutorial about Danfoss VSD control & communicate with Ethernet cable. Good Luck.!!!
Then you need to ask a question. I can't guess! What are you trying to do? Did you watch Timers 1 (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tFgtkgBxwZI.html)? See the playlist. There are four videos on timer instructions.
Had a play with the calculator this morning with an analogy proximity sensor and it’s an excellent tool for getting what you want quickly. Rest assured I will pass the link to my apprentices when we start programming. Keep up the good work.
Excelente vídeo, ganhou um inscrito. Poderia fazer um vídeo ensinando como fazer para integrar o logo com programa ignition achei bem interessante animação dos dasboard
Correct. This is explained clearly at around 3:27. While you lose some resolution, you gain a ""live zero" and save the cost and space of an analog module. You said, "... or the same resolution." I don't understand that part of your comment. Thank you for the feedback.
Great videos, well explained. I'm trying to use an analogue input to vary the setting of a timer as I would in a normal PLC. is it possible to do this in logo?
When watching one of your videos just a moment ago i thought to request a video explaining differences between the LOGO controller, but here we go! You have it already. Nice. Only i can try to guess that you haven't got a video explaining additional I/O modules and if all controller models can controll all of it and how many of I/Os can be added. Or of you have this video already, then soon i will find it. ;) Thank you.
Thank you for the nice feedback. No, I haven't started to look at add-on modules. I still have a lot to do on the basic modules, the web server capability, cloud and networking. You'll have to read the manuals for now!
I think you’re getting ahead of yourself. I was referring to your comment about ‘understanding’. Millions upon millions use computers successfully every day without having to know what each component does in the circuit. Now do understand my previous comment?
That's a nice trick! A slight recommendation would be for the print base to be three pieces, the handle, the actual base and the vessel, with the vessel in one piece and on its head, that would achieve the ideal 3d printing orientation to avoid warping, and if for some reason you need really good tolerances you could print it with a raft
Thanks, Eric. I had a couple of constraints. I have a really cheap, low-quality printer at home but decided to make these on an Ultimaker 2+ at my local library. (It just worked!) The print bed is about 22.5 cm square so it was a tight fit. It also put all the support on the inside which kept the outside clean. I think I could have avoided most of the distortion by fitting the lamp top during the glue-up. It would have held the lamp sides in the correct relative positions. Have a look at ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-PWJ1t3-23SE.htmlsi=TVp8rnDAgg5_9OKE to see more!
@@QuickPLC-kh5of I see, in that case you may benefit from creating a guiding lid, just some "jigsaw" pattern on the bottom that will help you align everything else, you could also get some ideas from wood joins, I've made my fair share of them for 3D prints and they do wonders
Thank you for the feedback. We hope that your lives can get back to normal as soon as possible. There are many refugees from your country in my town in Ireland.
Hello! I have a question again)) - did I understand correctly: the NOT block in one cycle has an output of 1, in the next cycle it has 0 and then everything repeats?
Hello. Everything is fine! Starting from 1:37, you assemble a circuit with recursion to the NOT block. In the first cycle, the output of the NOT block is a logical one, in the second cycle it is a zero, and so on, each odd cycle is equal to a logical one, and every even cycle is equal to a logical zero? It turns out that the block does NOT switch its state in each new cycle?
Ah, yes. Have a look at the "LOGO! M & Q and the program scan" (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Bm6qlgkng1M.html) where I go into some detail. I think this will answer your question. Follow that up with the "LOGO! Shift Register" (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tsi72VobvYg.html) video and you'll be expert! Let me know how you get on.
I used Inductive Automation's Ignition system. The Perspective module is designed for browser applications. The full software is expensive but you can use the two-hour trial mode indefinitely (with a manual reset) or use the free Maker edition. They have an Inductive University with online training. I'm hoping to make a video of using Ignition as a HMI for the LOGO! I'm glad you liked it.
Thank you for your feedback! I really liked your videos, although I haven’t watched the whole playlist yet. I will get acquainted with the program! Thank you!
Great videos and definitely the best I've come across (I'm studying EE lvl 3). The only improvements in my opinion would be some real life examples of how the less common blocks could be used. Eg, in what scenario would edge be useful.
Thanks for the feedback. I want to finish off the basic operation tutorials first but may slip in some application videos too. I'll take note of your suggestion for edge-trigger applications.
