PLC vs SCADA vs DCS

What's the difference between #PLC #SCADA & #DCS?
A PLC, Programmable Logic Controller, reads inputs, executes logic, and writes to outputs.
A SCADA, Supervisory Control and Data Acquisition connects to a group of PLC's and provides remote monitoring, control, and alarming.
A DCS, distributed control system, has both SCADA and PLC functionality. The PLCs are sometimes called RIO or RTU units often run proprietary or application-specific code, such as a rolling mill DCS.
SCADA can then connect to a DCS using drivers such as Kepware Technologies to integrate the DCS system with other applications across your plant/enterprise.
Hope this answers your question!

[@asab0777]

Thank you for the excellent explanation! The use of specific analogies and examples was also very helpful.

[@4.0Solutions]

You're very welcome!

[@jessicaflores3944]

I've been learning about all these components and systems for a few months now and after this video it has all magically clicked. It feels pretty empowering to finally "get it".

[@4.0Solutions]

Thank you Jessica!! Glad you finally get it! Please join the Discord Community! www.iiot.university/discord

[@alfredojrflores9810]

K.I.S.S. = keep It Short & Simple - straight forward & yet detailed explanation, thank you

[@tanvvichaudhary23]

Must say, your explanation is as simple as it can get. I am working for a company and planning a marketing strategy for their automation products. Even though I am an electronics engineer, I have never tread tht technical path so I had to rely on internet for my research and product and segment understanding. I have found your videos so so useful that now I have better clarity and understanding as to how to approach things further.

[@paulkomba944]

Fine I got u well

[@hanisahjaafar5435]

Thank you for this video sir, so if SCADA can manage more than one PLC it could be a DCS or not? Thanks again sir!

[@4.0Solutions]

SCADA can manage more than one PLC and more than one DCS yes. A DCS is typically integrated.

[@wyc2462]

Master of 4.0 Solutions.

[@4.0Solutions]

Thank you!

[@shahidiqbal5273]

Dear Sir,
I have around more than 10 years of field experience in the E&I works where i am directly involved in handling field instrument connected with different PLC and DCS based control system...... Your lectures are always upto the mark, I want to do some research where the conventional SCADA with even OPC or ERP cost can be reduced using IoT cloud........ Could you please guide me in this direction....
..
My area of interest is AI, Embeded system.. microconterollers, Arduino, Resbarry Pi.... Etc.......

[@4.0Solutions]

Reach out to [e-mail] and our team can help.

[@syahirahshukri7148]

Sir, what is the application of SCADA? And what are the types of remote stations used for SCADA?
Thank you sir.

[@4.0Solutions]

czcams.com/video/BnPgwMKPZOk/video.html

[@nurulsyairahmohdfadzil5041]

Sir, may i know what makes DCS more beneficial than SCADA ? and what is example of SCADA's application ? btw thank you for the video, it helps a lot :)

[@4.0Solutions]

Hi Nurul! Have you seen this video yet? czcams.com/video/BnPgwMKPZOk/video.html

[@farraadeebah423]

in the vid, it mention abt the PLC change the output on a certain condition. my question is how can it change the output? does it have a disturbance in the system? and is it a big change or a small change ?

[@4.0Solutions]

It will change it's output based on what all of it's inputs are and the logic that it runs to determine what it's outputs should be based upon it's inputs. Think of it like a "black box"

[@Muddassarshah969]

Sir do you have more video about PLC & Scada if yes kindly paste the link I want to learn more about that

[@4.0Solutions]

Glad this was helpful for you! We will be doing some additional whiteboard lessons soon, but if you are looking for practical, basic information, you might take a look at this channel as well > czcams.com/users/realparsfeatured

[@vusalgozalov]

Thanks. By the way you look like Hank from Breaking Bad

[@diyanaderaman5337]

sir can we decide which one is better between these 3? btw thank you for your great explanation sir:)))

[@4.0Solutions]

There is a place for each!

[@norfarishamasturafissol7729]

Thank you, Sir.
Sir, if PLC system has problem, does it give us an alarm like SCADA system does?
Thank you, Sir.

[@4.0Solutions]

Yes it does! If you configure it to do such.

[@ciah5998]

Hi sir! May I ask something? So from your video, it means that PLC is under SCADA, and SCADA is under DCS or I'm wrong? 🤔 But, between SCADA and DCS, which one is better i mean from their safety, technology and others, and why? 🤔 Other than cars, can we find DCS in other daily applications too? 🤔

[@4.0Solutions]

PLC is under SCADA. DCS is is own thing. DCS can also be integrated into SCADA. Check out the IIoT Mini-Course to learn more www.intellic.online/iiot-mini-course

[@youriregnaud8461]

Is answer to question 2 (Thingworx as DataLayer) is available on video?

[@4.0Solutions]

The short answer is no. Here is the answer on video (with timecode) czcams.com/video/ZPKUsqIYUTc/video.html

[@sarahaina7856]

Sir, so what is the difference between i/o system and fieldbus?

[@4.0Solutions]

Great question!

[@mohammadalifaimanshamsukam1910]

SCADA and DCS is quite similar but what is the sligh difference between them??

[@4.0Solutions]

Check out part II! Link in the description above.

[@lejlamony]

Hi. I need scada for on grid solar plant 155kw where to buy it.

[@qasrinasyazwanibintirostam694]

Sir, can i ask something ?
1. According from these two type, which is more advantages, is it SCADA or DCS ?
2. Does all types of cars use DCS ?
3. Which one is more save in cost for using it in industries ?
Thank you sir !

[@nurulhusnamohammadmisroji6315]

I wonder the same things

[@4.0Solutions]

They both have their place in industry! It really depends on the application.

[@nurulnajihah5871]

What are the benefits of using the SCADA, DCS and PLC?

[@akmalsyazani4342]

Oooo

[@4.0Solutions]

See what is Digital Transformation video on our channel Nurul!

[@ntcuong01ct1]

1 MES can control multiple SCADA in a plant, right?

[@4.0Solutions]

Yes

Sir why all tesla is using DCS. And how about the other cars?

[@4.0Solutions]

Yes they are all most likely using a combination of all of them.

[@muhammadhakimi250]

Sir whats the difference between SCADA and DCS ??
