What is Scada Systems? – An Introduction to SCADA Systems



What is SCADA System?

SCADA System refers to Supervisory Control and Data Acquisition System. Primarily, it is a network of all the machinery and equipment in the system connected through a centralised hub. The hub acquires all the data from the site. It includes information like machine status, process status, health of the machine, its throughput etc.

Functions of SCADA

All the equipment connected through machine control are operated through instruction sent over the web. The processing unit analyses the data and supervises the healthy functioning of the signals transmitted in the entire unit. The data is stored for valuation in a distributed database. The acquired data also has reference metadata stored for in the different database such as a programmable logic controller (PLC).

How does it work?

The complete SCADA systems has four significant units namely – data communication, data acquisition, information or data presentation and monitoring and control system. With complete symphony in the above four mentioned units, the entire operation of the automation system can be monitored. The data acquisition system fetches real-time data from all the connected machine units. The data reports about the status of all the components and sensors, where data communication network comes into play. The system ensures accuracy in data being transferred through the internet protocol. Once the data is collected, the processing unit analyses the data and presents it to the operator through Human-Machine Interface (HMI).

The comprehensive system works in close connection with predictive maintenance also. The data relayed by communication system after processing is also analysed by this system to detect any shortcomings that may occur in the system. This reduces the susceptibility of system breakdown or expected downtime due to a faulty line.

Application of the System

Although this is a new technology, businesses have already leveraged the technology in both the public and private sector. It has brought about immense satisfaction in the operation managers because the system makes the production line foolproof. This also streamlines packaging and delivery lines following the processes. The overall automation and process control has helped to save a significant amount of money and time. This is the reason why many more enterprises are looking for automating their industrial processes. With the Industrial Internet of Things taking the front seat, it is essential to look for companies helping businesses step towards automation. Schneider Electric India is one of the significant names in the research and development of the automation industry. It has not only brought these systems to common units but also helps the employees to upskill their knowledge by training them how to operate the machinery.

Benefits of Hiring a Software Development Company



Want to build a software and you are confused between hiring a freelancer developer or a software development company? Then there is a high chance that you have figured out that software development company would be the best for you.

But the question is, why hire a software development company? Well, to help you out with the question, I am going to talk about some of the top benefits of hiring a software development company.

So let’s just head into the topic without wasting much of the time:

Benefits of hiring a Software Development Company

 Skills and Expertise

One of the main reason to hire a software development company is that they are backed by skills and expertise that you do not get with the freelancer developers. Freelancer developers often lack skills and exposure. Hence they fail to deliver the best in the business performance.

However, the thing about professional software development companies is that they have a huge team. And in a team, they have people who are skilled in different things. So whenever they get a project, they know what kind of framework or libraries are required for the project. As well as they easily develop the software.

Less Expensive

Software development companies are less costly compared to freelancer developers. When you hand over a project to a freelancer, there is going to be only one person who will do your job. Hence the developer will be taking more and more time to complete your job. And as days pass, your expenses increase too.

But software development companies are backed by a team, and there are a bunch of people who are working on the same project. As a result, it takes less time to deliver the project, and you pay less than what you pay to a freelancer developer.

Saves Time

As a business owner, your time is money, and you cannot spend too many days to get done with a project. As it would only cost you more money. And that is the reason why you should work with a software development company for your custom software development project. Software development companies value your time and deliver their project at a time. So you can be on your deadline while getting satisfactory work.


When you work with a software development company, you get to taste the reliability. Software development companies make sure that they are getting satisfactory services. Even if you want to make any changes in your software, then doing so is also pretty easy.

But the same is not possible with a freelancer. Once you are done with your project, you may not find the freelancer again. And this is where software development companies come into play.

Final Words:

So those were some of the top benefits of hiring a software development company. Although I would only recommend you to go with a software development company if you have a big project to be completed. For small projects, freelancers are perfect.
