Sequential Function Chart (SFC) Programming for Beginners

[@davidpalmer963]

How the specific information is presented in these Videos, is very well thought out. IN one paragraph alone, at least 10 key functional points are administered to the viewer. Concise and to the point....That's REAL PARS!

[@realpars]

Thank you very much! We're happy to read that, David.

[@NattePannenkoek2]

Hele toffe video!😁👍🏻

[@realpars]

Dank je wel!

[@davebennett5069]

thank you for expounding upon the specific reasons i don't use this. SFC is simultaneously more complex and less capable than other languages.

[@AlexandreSantos-gg9il]

RealPars is fantastic! from Brazil thanks.

[@realpars]

Glad you like it, Alexandre!

[@PLCTrainingforBeginners]

So many thanks. From Vietnamese with ❤

[@realpars]

You're very welcome!

[@yssing]

I use that all the time when analyzing any given situation that needs to be translated to ladder or ST.

[@jdgakuba7137]

Thanks a lot Real Pars!

[@realpars]

Our pleasure!

Hi every one in real pars inspite of the differences of language between us you making mix between fun & learning in the same time you fired the flame of pation on me when i watched a single video in your channel & then i became adicted to learn more & more to became better automation engineer thank's for every one for the great efforts that you made for every single moment of your time that you spent to help us learn & joy & i hope to see you on the top always thank's from the ❤ Real pars.

[@realpars]

Thanks a million for your kind support, Muzamil! We truly appreciate that.

[@aliabd-alhalim4695]

Well...Its awonderful explanation with u wish u always more success.

[@realpars]

Thank you so much, Ali!

[@ahmedmaher5247]

Thanks for your efforts ❤️

You're very welcome!

Thanks from Bangladesh

[@realpars]

You're very welcome!

[@joelowens6862]

I have printed and studied several PDFs about SFC. It does seem unnecessarily convoluted and the transistions are vague, in my perception. Ladder Diagram seems the most complete, and Instruction List is more like assembly language for PLC. So I think LD and IL are probably the areas where I am going to put more focus.

Realpars, but please can you place the "JOIN" button beside the "SUBSCRIBE" button on your channel so that we can contribute to sustain this (our) channel? Thanks.

[@realpars]

Thanks for your support and your suggestion! I will be happy to forward your feedback to our team. Thanks again and happy learning!

[@davidpalmer963]

tHAT IS BECAUSE REAL PAR'S IS DA BOMB!!

[@realpars]

Thank you very much!

[@mynameismootokoita]

good explanation

[@realpars]

Thank you!

[@DemetriusHazardus]

Very nice 👌

[@realpars]

Thank you!

[@hectorenriquesantandermeza5208]

Thank you Real Pars! That was an amazing explanation. In some cases a grup of mathematichal equations are used to make a transition from SFC to Ladder diagram. Im not sure but there is another method used to draw a sequence called "Time Phase Diagrams" in wich the status of two or more inputs and outputs are arranged in a bidimentional graphic fashion with time variable, depending if IO are digital or analog, then you should construct a set of equations and link them by their properties to develop the ladder diagram. I think it will be great if someday you could make a video related to time phase diagrams. Greetings from Ecuador!

[@realpars]

Thanks for comment and feedback! I will happily pass this on to our course developers. Happy learning!

[@deniskalugin7984]

Thank you, RealPars! Always informative and easy-to-understand explanation! P.S. I hope I will be able to focus on studying your offline courses and continue to learn PLC and HMI programming. For thoose, who did not start yet, I highly recommend them.

[@realpars]

Thanks a million for your kind comment and support, Denis! We truly appreciate that. Always feel free to reach out when you have any questions or concerns, we're more than happy to help!

[@sumeetdeshmukh9911]

Hi, thanks for video! I am working with S-7 1200 1214 dc/dc/dc PLC, and in TIA portal the graph option is not available in FB. I then tried SFC but it is looking like STL. Can you tell me how to resolve this issue.

[@realpars]

Hi, @sumeetdeshmukh9911. Thank you for your question! We understand your point. Here’s a link where you can find information about Siemens PLC types, documentation, and software. details.support.industry.siemens.com/cs/document/109744173/documentation-for-simatic-controller?dti=0&lc=en-WW

[@srujanm8109]

Hi, Thanks for the video. Could you tell me what exactly is the difference between N and P (Impulse)? Thanks in advance!😊

[@realpars]

Thank you for your comment! In this video, we did not discuss N or P pulses. Or have I misunderstood your question? Regardless, I will happily go ahead and forward this as a topic suggestion to our course developers.

[@Jzzzzx]

Question. Would it be possible to reset an input like a start button in sfc? Ive tried to reset the input but it doesn’t seem to work. Thanks

[@realpars]

If the Start button is a physical input (an Ix.x address), you will not be able to reset it from an SFC. It could also be that other logic in the PLC keeps the variable in question in the ON state. SFCs do not "override" other logic. Some PLCs have different "rules" about setting variable states within an SFC. Make sure you know what your particular processor allows.

[@George-Smith]

Thanks for the video But am in Cameroon and i really love AUTOMATION engineering i don't know the guide on how realpars could help me

[@mdnezamuddin6219]

Tnx

[@ducati651]

Thanks enginer

[@realpars]

You're welcome!

[@alexanderskusnov5119]

LD and FBD are old. Now we use CFC (Continuous Flow Chart). And for text nobody uses IL, only ST.

[@YewrMan]

The standard is around nearly 10 years. It's just an explain.

[@SakeBarSushi]

TPo

[@ranmjj]

SFC... why?

[@TOM8940]

The is one of the programming language in the PLC standard

[@ranmjj]

@@TOM8940 I know... one that we just really don't need. Structured text with opp extensions till something else better will come. It's time we throw away what does not make sense.

[@ЧупакабраИнгерманландская]

@@ranmjj Nonsense. I advise you to read about finite state machines. And it will immediately become clear that SFC is the highest language for programming robots and machine tools today.

[@ranmjj]

There is a reason why no one in the IT world no one uses graphical languages... these should fi ally die. Everything u do graphically can be done textually.

[@ЧупакабраИнгерманландская]

@@ranmjj But we are not in the pure world of IT. It is much easier for maintenance personnel, such as adjusters, to understand the graphical diagram for maintenance than your "text", the more they do not have to be professionals to search for problems and failures.
