What is the difference between PLC and SCADA?
In today's post, we will know what is the difference between PLC and SCADA and also talk about the electrical interview question asked by the interviewer on PLC and SCADA.
What is PLC?
The full form of PLC = PROGRAMMABLE LOGIC CONTROLLER
By its full name, we know what a PLC is. If we talk about using PLC, with the help of this, we can program and control any of our equipment.
Example- Suppose I have a bulb. Now I want to run this bulb for 1 min, then after closing 10 sec, I want to run 5 min and this process should go on all day. So in this way, the bulb can be easily carried out with the help of control PLC.
We can control any electrical device according to us with the help of PLC, to do this we only have to do programming in the software of PLC, after that the device starts running according to the way we have programmed. is.
What is SCADA?
The full form of SCADA = Supervisory Control and Data Acquisition.
SCADA is used to supervise our equipment. Example- Suppose the company has 3 motors, SCADA takes care of all these things for how long the motor is running and how much Ampere current is taking. Data Acquisition in the name of SCADA means to store the data.
SCADA has two main functions.
- First of all, SCADA performs the monitoring of our system. That is, it monitors all of what is happening inside the company. For example, which motor is running in the company and which is not running, apart from that how many ampere current is the motor takes. We can monitor all these things with the help of SCADA.
- Apart from this, SCADA works to store the data of our system. Example- Suppose if our company has three motors, and we want to know how many hours these three motors have run throughout the day, and which motors are closed for how many hours, then we can easily find all the points by taking the help of SCADA. So in this way, SCADA also works to store the data of the system.
Difference between SCADA and PLC
Till now we have come to know what is SCADA and PLC are, now we will know the difference between PLCA and SCADA.
PLC vs SCADA
- PLC is a kind of hardware, while SCADA is a kind of software that we install on our computer.
- PLC works to control our devices, meaning with the help of PLC we can turn our device off by putting different conditions. While SCADA shows the ongoing work in our company with the help of Animation on Computer. As the tank is getting full in the machine or a lift is going up and down, all these things are shown to us in the form of SCADA graphically or Animation.
- PLC works to control whatever machine is inside our company, that is when to turn off the machine, at what time the PLC does it. Whereas with the help of SCADA, we can store the data along with the monitoring of the system, that is, we get the history of how many hours a machine is running and how long it has been shut down with the help of SCADA.
Interview Question Asked
Now if you ever go to give an electrical interview and you are asked the difference between SCADA and PLC then you have to give this answer.
Difference between PLC and SCADA?
Answer- PLC's full name is Programmable Logic Controller. It is used for automatic control of the machine. All PLCs have a Programming Software, inside which we program the machine according to how to control it, after which the machine runs and stops according to that program.
The full name of SCADA is Supervisory Control and Data Acquisition, a software that is installed in a computer. With the help of this, monitoring the machine becomes very easy as SCADA shows us the work going on in the company in animation and graphically. Apart from this, it also stores the data of our machine.
So, I hope today many answers related to your PLC vs SCADA would have been received. If you still have any questions related, then you must contact me on my social media accounts.

Have a Good Day!
Happy Learning!
