Control and Supervision
It is impossible to keep control and supervision on all industrial activities manually. Some automated tool is required which can control, supervise, collect data, analyses data and generate reports. A unique solution is introduced to meet all this demand is SCADA system.
SCADA stands for supervisory control and data acquisition. It is an industrial control system where a computer system monitoring and controlling a process.
Another term is there, Distributed Control System (DCS). Usually there is a confusion between the concept of these two.
Components of SCADA
1. Human Machine Interface (HMI)
It is an interface which presents process data to a human operator, and through this, the human operator monitors and controls the process.
2. Supervisory (computer) system
It gathers data on the process and sending commands (or control) to the process.
3. Remote Terminal Units (RTUs)
It connect to sensors in the process, converting sensor signals to digital data and sending digital data to the supervisory system.
4. Programmable Logic Controller (PLCs)
It is used as field devices because they are more economical, versatile, flexible, and configurable than special-purpose RTUs.
5. Communication infrastructure
It provides connectivity to the supervisory system to the Remote Terminal Units.
SCADA System Concept
The term SCADA usually refers to centralized systems which monitor and control entire sites, or complexes of systems spread out over large areas (anything between an industrial plant and a country).
Host control functions are usually restricted to basic overriding or supervisory level intervention. For example, a PLC may control the flow of cooling water through part of an industrial process, but the SCADA system may allow operators to change the set points for the flow, and enable alarm conditions, such as loss of flow and high temperature, to be displayed and recorded.
The feedback control loop passes through the RTU or PLC, while the SCADA system monitors the overall performance of the loop.

I really learnt very much from your blog. Thank you for share this information on PLC SCADA. Please keep share, I am waiting for your next blog. PLC SCADA has very good career, PLC programmer is the most attractive job in engineer field. PLC SCADA Training is must for doing the job in this field.
the subject need to be more advanced
I would like to give me a brief concept if its possible and can work that to design a hydropower plant using SCADA software.
I am in Port harcourt,Nigeria. I want to be a real time SCADA engineer, how do i get started
Hi I am a computer engineering student. My family members taken a municipal project for water purification worth of 35 crore. They asked me to join with them. I m good at test automation selenium likely that. I don’t know scada. But they pleased to . so can I join in that as scadac engineer???
Good blogging for beginners in engineering, the post also help everyone who wants to know about SCADA systems. It is one gateway to control all the activities in a plant or a company. You can get information on the equipment from a good and reputed manufacturer like Chemtrols. All you neded is to just log into the website and heck for details. You can even ask for a quote.
I working on Twido PLC TWDLMDA20DRT and would like to control it using movicon-scada. For some reason I am not able to establish communication between PLC and movicon using Schneider comm drivers. Please guide me how to establish the communication.
Dear sir,
I am D.naresh, my designation is electrical engineer. Now am doing AUTOCAD Designer in panel board manufacturing company. Sometimes the clients are asking PLC & SCADA Connections to panel. But i dont know how to connect. I want to know that if PLC & SCADA Coaching is important for Electrical engineers
can you suggest a good training center to join the course…..pls

hi ! i’m prepararing for my ppt projet about SCADA and HMI .. can you help me please ??
Hi Engineer
What kind help you need.? Let me know. As i know the part ill help you on the subject layouts.
I want more information
please am just newly recruited in the SCADA dept.need more information.
Very useful domain….regarding plc,scada,dcs
Interested in knowing more for plc and scada filed of work and studies.
Thank you.
Sir me scada ralated information and vedio in electrical engineering career growth me increased .so please help me . more information send me sir
hi frnds,
lot’s of automation institute is there but less no of opportunities, whenever i am searching job in automation field at web portal i am facing only institute advertisement only,can u please tell me automation job portal name please suggest me.
thank ui
Hi do you have a scada for street lighting
BONSOIR .. je prépare mon mémoire de fin d’étude et j’aimerai bien avoir plus d’information (en français si c’est possible ) Merci
sent more details about scada & plc &sir tell me even about training centres nearest to belgaum
Please share more scada videos. also provide tutorial links to learn about scada and plc automation system. also please let us know how to do PLC programing.
Sir, Can u send me more scada video tutorial links? i want to learn about scada and plc automation system.
do you offer scada training videos for RSVIWE32.
please sent me article
I love this
O
I really enjoy the lecture and it is well understand. but i really want to no difference between RTUs and PLCs. Thanks while waiting for your respond as soon as possible.
More details required
Is SCADA different to BMS? Or it is just the same?
classic information abt PLC S SCADA rather than wikipedia
Heartly THANKS
Hi,
