DCS vs PLC | 5 IMPORTANT Differences NO ONE Teaches You! // Difference Between PLC and DCS

[@JosBrouwer1]

Yeah. DCS uses higher languages such as CFC. This creates a very high quantity of undecipherable code when compiled (in Step7/PCS7), which caused Stuxnet to go unnoticed for a long time (remember?). It surprises me that for DCS the S7-400 series is representing, while as PLC the far more powerful S7-1500 series is representing. And also: for PLC programming the STL is (fortunately) being phased out, S7-1200 series no longer supports it. STL should have been phased out already with the introduction of the S7 series in my humble opinion. Most PLC programming nowadays is SCL, but I also like to use Graph (SFC/Grafcet) for sequences. LAD can be very useful too, anyone with some understanding of electrical diagrams can understand the working of that. PID controllers and motion control in PLC is also no problem at all (I did motion control in PLC already in 1988).

Thank you for your comprehensive input, Jos! These were absolutely important points to consider.

[@robertomelo8815]

Basically, the S7-400 is the supported CPU of Siemens DCS up to date, and ET200SP is the remote I/O... No 1500 supports this for now, but that doesn't mean the S7-400 is outdated or phased out. Siemens continues to update the 400 line-up with much superior processing and capacity than the old ones. In some specific uses, such as PC-S7 DCS, Safety (F) and redundancy (H) systems, there is still preference for S7-400 models.

It is PERFECT indeed. Simply clarified imortant points, which were always a question for me. Thank you. Keep it up.

[@Upmation]

Happy to hear that Saeid. You are most welcome!

[@bouafiasaber3764]

Thanks for detailed videos, I don't know why this channel is not popular yet , Please make more videos , don't interrupt .

[@Upmation]

Hey Bouafia, thank you for your comment! For that, we need your support to share these videos and spread the word in other social media. We're planning for more videos in the near future. So please stay tuned. Thank you!

finally, someone who make me understand the difference between plc and dcs, after a lot of videos, and vague explanations, thanks sir ❤️

[@Upmation]

You're very welcome! Glad it helped!

[@andresgallardomansilla7444]

Such a useful video, and as you say this are normal never mentioned. Ideas for future videos: 1) FDS (Function design specification) 2) Industry 4.0 or IIOT

[@Upmation]

Hi, Andrés! It's great to hear it was useful to you! Thank you for your comments and suggestions. I will definitely transfer them to the team. Particularly, IIoT and Industry 4.0. Thanks again.

[@SOGUIREL]

This tutorial put DCS and PLC difference in the ROM MEMORY of my brain.

[@Upmation]

Hey Maurice! Such a metaphor! Happy it was helpful to you!

[@jaikrishna7020]

Great Content. It will be very useful if you make playlists on various communication protocols. Your presentation skills will take these topics to Pro level....

[@Upmation]

Hi, Jai! It's a great suggestion! We'll definitely consider it and will publish some videos about Industrial communications and their protocols. Thank you!

[@vickyoli]

I just had to learn about this and is this by far the most useful video and make the different and similarities clear.

[@ahmedmohamedhassan1033]

the greatest video I've ever seen about difference between PLC & DCS , Thank you very much

[@kharazmkharazmi8236]

Thank you very much, your explanation was really great . God bless you.

[@gabry96colo]

this is not a matter of cpu models but a design philosophy. in a dcs the process is delegated to a slave processor that is rarely on main cabinet but "on field" in this way, aside from isolating the machine from the plant, it makes also the electrical wiring a breeze: instead of all the io signals to link with main cabinet you can just use one network cable in a loop and instead of transmitting all io-link data to process on main cpu you send only the setpoints and receive the result. this is essential when comminucation stability is not guaranteed and latency is not idea to have fast response

[@akhilesh117]

Very nicely explained...please make more videos.👍

[@Upmation]

Thanks a lot! Of course, we will. Please stay tuned for the upcoming videos. You can take a look at our website (upmation.com) and leave your email in there so that we'll inform you about other videos and Free courses.

[@engrmdzohurulislam481]

I'm watching from Bangladesh! Your tutorials very Nice! I hope will more video about plc related electrical drawing learning video! Please

[@mohdhafizuddin2114]

After 6 years in the industry, now this vid enlightens me. My experience with DCS is zero compared to PLC.

[@Upmation]

It's amazing to hear that! We are very happy to help.

[@belovedpearl3274]

How much year you have experience in plc

[@vishnuprakash3187]

This video is so much informative to a newbie, thanks. well presented.

[@Upmation]

Glad you enjoyed it! and you're very welcome!

[@hmrd8555]

Great going sir. Thanks for this great presentation

You're most welcome, Harish!

[@momarmbow8265]

very interesting contents why did you stop your videos ?

[@Upmation]

Hey, Momar! Yes, it's been a pretty long time since we could not publish a new video. But because of the emails and supports, we receive from passionate fans like you, we decided to get back up and continue.

[@athilaldurry5880]

Hi, Sandesh! Thank you very much. Enjoy!

Nice very good video Can you make DCS vs SCADA ??

[@Upmation]

Thank you! Of course, we can! I'll transfer your suggestion to the team.

[@vikalsharma]

Best ...it's perfect comparison.

[@Upmation]

Hi, Vikal! Thank you!

[@ardalanizadi3202]

So great! Thank you

[@saifalniamah9002]

The videos are useful. I have one question : I am looking for a WinCC V7. 5 (explorer). How can I get it?

[@Upmation]

Thank you very much! I'm afraid, I don't know how you can get the older versions that are most probably not supported by the company anymore.

[@ShivamBhatt00]

In dcs we can't add progarm ?

[@vladx3539]

shouldn’t you be discussing scada in this topic?

[@skidst]

Just one remark. DCS stands for Distributed Control System.

[@Upmation]

Thank you for the comment. Distributed and Decentralized are both used for DCS and both have the same meaning.

[@alexr1680]

@@Upmation Distributed means computation is spread across multiple nodes instead of just one. Decentralized means no node is instructing any other node as to what to do.

[@andreyace8768]

[@simplereef4854]

Ever hear of DeltaV PK HAHA

[@gene_Code]

Lmao some other video says it is Distributed Control System. Which is it

[@Upmation]

Distributed and Decentralized have the same meaning in this context. You may find "Distributed" more common.
