PLC 101 - Everything You Need to Know About Programmable Logic Controllers

We are aware of how industrial processes have been revolutionised by automated machinery. Undoubtedly, these machines have evolved to become essential tools for enhancing productivity and driving innovation. Whether your work involves pricing garments or devising packaging solutions, the integration of automation has fundamentally transformed the way we approach these tasks. But all these automations are not possible without a critical invention called a programmable logic controller (PLC).

In an industrial setting, a Programmable Logic Controller (PLC) operates as a computer system. PLCs, provided by reliable programmable logic controller suppliers, make decisions regarding associated outputs based on the monitoring of the system's inputs. PLCs often serve as the heart of a predictive maintenance system, alerting firms to potential issues before they escalate into major breakdowns.

In this blog, we will delve into everything you need to know about PLCs, including their benefits, functionality, and their future in the market. Keep reading to learn more.

The benefits of using PLCs

These days, PLCs have a number of benefits over hardwired relays, including dependability, flexibility, affordability, speed, faster connectivity, and sophisticated data processing capabilities. The most distinctive benefit of PLC systems is their reprogrammability. As a result, they are very flexible in processing modifications or requirements for monitoring applications.

  • PLCs are an established technology that has undergone extensive testing and study over time. Various studies are available for different types of PLC that help guide integrating and programming them.
  • PLCs come in a wide range of price ranges, including many basic types that are quite cheap and frequently used by small firms and startups.
  • PLCs are incredibly adaptable, and the majority of PLC versions may be used to handle a range of different systems and processes.
  • The benefit of PLCs is that they are completely solid-state electronics, preventing any loss of moving parts. As a result, they are easily strong and dependable to the harsh environments in industrial buildings.

How does PLC programming perform?

The PLC's control strategy or logic is defined by its programming. Any machinery's input devices can receive signals that are transmitted to the PLC via the connector rails. The bits in the PLC memory are then used to store these signals.

The device on which the program is written is the PLC programming device. The CPU then reads the instructions from memory and executes them, which is how the output devices are controlled.

The Opportunities for PLCs

The market is still seeing new products, from industrial-embedded hardware to devices like Programmable Automation Controllers (PACs), which combine PLC capabilities with higher-level PC functionality.

PLCs continue to be popular despite the introduction of these new products due to their usefulness, cost, and simplicity. And for many years to come, software like Ignition will make it possible for organisations to maximise their usefulness.
