Why Your Business Needs Programmable Logic Controllers

Programmable Logic Controllers or PLCs are an integral part of industrial automation and control systems. PLCs are minicomputers without a monitor, mouse, or keyboard. They are specially built to withstand the harsh environment of an industry. As such, Programmable Logic Controllers, can withstand heat, cold, moisture, dust, and other such factors.

Apart from these features, PLCs are also highly flexible. It means that the programmer can change the machine’s functionality to suit your needs by changing just a few programs. It is easy to speed up an operation or manipulate the inputs to get the desired outputs.

How Does a PLC Work?

The PLC works the same way as a computer does. It receives data or input from the devices connected to or through the sensors installed, processes the data, and delivers the output as per pre-set parameters. A PLC can easily monitor and record information based on the input and output. So, PLC can help you track information such as temperatures, productivity, auto start, and stop processes. PLCs are generally failsafe and hence preferred to the traditional control systems.

PLC programming language uses symbols instead of letters, and a PLC has an I/O unit, communication port, and Human Machine Interface. However, PLCs can also have other features depending on their size and application in various industries. The functions and interactions rely on the program on which it runs.

Why Do Businesses Need PLC?

PLCs are used to control machinery as they are the components that make decisions according to the set program. Almost all modern-day machines contain a PLC unit because it facilitates easier control. All automated factories and machines have PLCs, and without a PLC, it will be impossible to adapt the device to your requirements. For instance, PLC makes it easy to turn up the production volume from 3000 units per hour to 5000 units per hour. All you need is to change the program, and the machinery is set to deliver the new target.

Without PLC, the Following Problems Might Occur:

  • Stoppage of production
  • Wastage of resources as new machines with greater capacities will have to be installed every time there is a surge in demand.
  • Customer expectations not met because of undue delays
  • Revenue loss

Benefits of PLCs

If you have a piece of machinery with PLC, it brings you better:

  • Peace of mind – correctly programmed PLCs can eliminate inconsistency and ensure better control and monitoring of industrial operations
  • Scalability – PLC programming helps to scale up your production lines and equipment quite easily
  • Better integration – good PLC programming provides better integration with future automation systems without needing to reprogram all your controls
  • Performance – PLCs ensure machines offer 100% performance
  • Security – PLCs can help secure your machinery from external threats and interferences by adding security features to the program

Apart from these, PLCs improve overall productivity through lower power consumption, better systems control, and record-keeping. They also help in optimally assigning the available workforce to ensure better productivity. PLCs are flexible, robust, and affordable.
