Have you ever thought about how things in your house can now connect to the internet by themselves? Or how regular devices have recently become smart? It’s because of something called the Internet of Things, or IoT. The Internet of Things is like a network of everyday appliances that now have small computer systems inside them. These systems let them share information and make your life better.
Now, these microcontrollers and embedded software systems require a controlling system or a small CPU of their own. That’s where programmable logic circuits come in. You might be curious about what this is and what it does. Keep reading to find out more.
What are Programmable Logic Circuits?
A programmable logic circuit or controller(PLC) is a type of computer that controls and manages appliances and devices. It turns normal standard appliances into smart appliances (like stoves, fridges, and washing machines), security systems, and home hubs. It’s used to automate tasks like turning on lights or adjusting the temperature in your home.
They are also predominantly used for the automation of industrial processes like control machines in factories, on amusement park rides, and in light fixtures. PLCs are used in lots of different industries.
Why is Programmable Logic Circuit important in IoT Devices?
As we have seen above, a programmable logic circuit (PLC) is a small electronic device that controls how a machine or process works. It uses input data to decide what the machine should do and then sends out instructions to make it happen. PLCs are important because they help automate important tasks. Now let us see some reasons why PLCs are important for IoT-
Monitor Industrial Operations
Programmable logic circuits are most commonly used across industries as controllers for industrial equipment and processes. They are used to monitor the progress and appropriately control the systems to maintain the process.
Testing and Measuring
In many industries, a rigorous testing and measurement routine needs to be followed. Programmable logic circuits are one of the best ways to automate the process and ensure consistent results every time.
Execute process-type functions
A programmable logic circuit takes in information about what’s happening in the system (like temperature or pressure), decides what actions to take based on that information (like turning on or off heaters or fans), and then sends out instructions to make those actions happen. So, for example, in an HVAC (Heating, ventilation, and Air Conditioning) system, a programmable logic controller helps control things like heating, cooling, and ventilation to keep the environment comfortable and efficient.
Wrapping Up
The advancements being made in the field of IoT promise a lot of cool and fun innovations in the near future. Oracle even predicts the number of devices connected to the IoT will rise to 22 billion by 2025. Thus, it is important to understand how it works. If we take a peek under the hood of IoT, we see that a programmable logic circuit lies at the crux of this revolutionary technology.
