PLC VS DCS | Key Differences #PLC #DCS #differences
==========================
Difference between PLC and DCS
==========================
PLC for Discrete control like automobile industry....DCS for analog control like oil and gas
PLC centralized DCS distributed control System
High Response time DCS,
Monitoring OF DCS, PLC Need HMI
DCS predefined function
Response time of PLC is high
DCS takes much longer to process data, so it’s not the right solution when response times are critical safety systems require a separate controller.
A PLC can only handle a few thousand I/O points or less
DCS, which can handle many thousands of I/O points and more easily accommodate new equipment
Redundancy in DCS
Frequent process changes
PLCs are best applied to a dedicated process that doesn’t change often.
Logic development
PLC can programmed be programmed based on our application.
DCS comes with built-in control functions
Cost of DCS is high
PLC or DCS Which is Right for Your Operation?

Great platform for learning

For me, I find ladder logic easier to trouble shoot. That is why I am more apt to use PLC. I do work in the automotive industry. But we use multiple PLC's fashioned similar to a DCS system. We build these in a layered fashion. As we change processes, we integrate each new system with it's own PLC.

[@nicholasfranks2616]

Totally Agree , i prefer multiple PLC's to control different process instead of a DCS system.

The lines between DCS and PLC systems are far more blurred than ever. As a DCS engineer the analogue aspect does still seem the largest factor along with the operator interaction. Great channel, well done!

I was asked about this question and I answered the same thing that you said. But the one who asked the question told me PLC's can also do analog control and they are also scale-able. The only thing that PLC will have difficulty in achieving is bump less transfer of CPU/Controller redundancy.

Very informative and clear difference between Plc and Dcs understood...

[@makwanashivam1947]

thank u for deep knowledge

[@MuhammadShahzad-dx5je]

#awesome

[@akashbhosale3580]

Thank you sir
Keep making videos for instrumentation guys we r so thankful ♥️♥️♥️

[@abduMalik070]

Thanks brother for the simple and valuable vedio...
Keep it up

[@reshmaaeie-4132]

Very informative video, thank you sir for this video.

[@sportsguru4062]

Superb sir

[@sherazsaeed3494]

Great video

[@syedmaaz6542]

Informative video thanks a lot

[@ITandAutomationAcademy]

👍

[@WeconTechnology]

thanks ,it is good video for me, to say the difference.

[@rathinasabapathyr5358]

Clearly explained 💥💥

[@TauroChuck]

PLC also will come with redundant configurations. So what is the problem having one controller for the whole plant

[@ali2900]

Dear, Your all videos are very informative & very helpful especially for the beginners. The way you explain all the technical things is simply awesome. Best of luck dear.

[@ITandAutomationAcademy]

Thanks Ali

[@maazahmad1631]

Can you please make the real videos of DCS and PLC, and their working system.

[@user-tp9cu6hq9k]

Crashing a PLC in a running plant is not a fun experience. so easy to do and can cause soo many problems. To many plants don't have redundant controllers to save on costs.

[@virtualobscenenature2123]

Can you make a video about scadas? I've seen for siemens some products like PC7 for this systems. But for AB i dont really know how it works, the only thing I know about this is Wonderware for screen design, but what or how is the data process?
nice videos dude, I have few days since I found your material specially Q&A sesions. Regards

[@sujitdhumal1]

PSC 7 is a process control system and it is a kind of siemens DCS system and it has many libraries according to process application,like for Cement and coal mining industry it has CEMAT lab,for oil and gas it has different libraries and for HMI they use wincc application for presentation and control of plant.

[@jamesamarh8157]

Perfect

[@TauroChuck]

DCS takes lot of time to process data. PLC is very quick. Siemens uses S7400 CPU for both PLC and DCS application. This is simply not true.

[@itzamiramir3389]

Start DCS training please

[@adlh9481]

Pon subtitulos en español, aún no donimo el ingles

[@onsiteempro8454]

Please put for us in full not in short form

[@akshaythakur6653]

Redundancy also in PLC ..!!!

[@ITandAutomationAcademy]

Its possible to have but by default hardware is not redundant

[@TauroChuck]

Why dont you use10 PLC to handle 10000 IOs.problem solved

[@shakilmia1702]

Start DCS training please
