PLC invention considered as top innovations in Automation Industries?

Posted by

he introduction of the Programmable Logic Controller (PLC) revolutionised the way industrial control systems were developed and put into operation, making it one of the most significant advancements in the automation sector.

Industrial control systems depended on intricate electromechanical relays, timers, and other components to regulate operations before the development of PLCs. These systems were frequently large, costly, and challenging to maintain.

All of that was altered by the introduction of PLCs, a small, programmable device that could be quickly modified to manage a variety of operations. Because Rockwell Automation PLCs are dependable, adaptable, and simple to update as necessary, firms can swiftly adjust to changes in production requirements.

PLCs have significantly contributed to the improvement of industrial process safety by offering cutting-edge safety features including emergency stop functionality and fault detection.

Overall, the development of PLCs has had a significant impact on the automation industry, improving the effectiveness, affordability, and safety of industrial control systems. It is still an essential part of several industrial applications today.

Who invented PLC?

Dick Morley, an engineer, created the first Programmable Logic Controller (PLC) in the late 1960s. Morley was employed by Bedford Associates, a business with headquarters in Bedford, Massachusetts, in the United States.

In order to make the process of automating machines simpler, Morley came up with the idea for the PLC. In order to replace the intricate and cumbersome relay-based control systems that were frequently employed at the time, he set out to develop a new gadget.

The “Modicon” (Modular Digital Controller), which was Morley’s first prototype, was based on a basic computer and could be programmed using ladder logic, a graphical language that is still frequently used in PLC programming today.

When the Modicon hit the market in 1969, firms who were searching for a more effective approach to manage their industrial operations adopted it immediately. PLCs have now evolved into a staple of industrial automation systems and are still frequently utilised in a variety of sectors.

What are the famous PLC manufacturer nowadays?

When the Modicon first appeared on the market in 1969, businesses looking for a better strategy to manage their industrial operations adopted it right away. PLCs are still extensively used in a range of industries and have developed into a mainstay of industrial automation systems.

  1. Siemens 

One of the biggest PLC producers in the world, Siemens offers a variety of PLCs for different industries and applications.

  1. Rockwell Automation (Allen-Bradley) 

Global leader in industrial automation, Rockwell Automation’s Allen-Bradley trademark is one of the most recognisable in PLCs.

  1. Mitsubishi Electric 

PLCs are among the many electrical and electronic devices that Mitsubishi Electric, a global Japanese firm, makes.

  1. Schneider Electric 

French multinational company Schneider Electric is an expert in PLCs and other energy management and automation systems.

  1. ABB 

ABB is a global corporation with Swiss and Swedish roots that manufactures a variety of industrial automation and robotics equipment, including PLCs.

  1. Omron 

PLCs are among the automation and control devices produced by Omron, a Japanese electronics manufacturer.

  1. Delta Electronics

These are only a few instances of well-known PLC producers, but there are several additional businesses that create high-quality PLCs for various uses. The particular demands and requirements of each application will determine which PLC manufacturer is best.

What are the main major components of PLC?

A typical Programmable Logic Controller (PLC) is made up of a number of significant parts, such as:

  1. Central Processing Unit (CPU) 

The PLC’s CPU, which is its brain, manages how the machine functions as a whole. It controls communication between the PLC and other devices as well as programme logic execution.

  1. Input/Output (I/O) Modules 

The interaction between the PLC and the outside world is provided by these modules. While output modules give signals to actuators and other devices, input modules receive signals from sensors and other gadgets.

  1. Power Supply 

The voltage and current required to run the PLC and any attached devices are supplied by the power supply.

  1. Memory 

Programme memory and data memory are the two forms of memory found in PLCs. While data memory houses variables and other information utilised by the programme, programme memory houses the logic of the programme.

  1. Communication Ports 

Human-machine interfaces (HMIs), supervisory control and data acquisition (SCADA) systems, and other PLCs, among others, may all be connected to current PLCs via communication ports.

  1. Programming Device 

Programmes are written, edited, and downloaded to the PLC using a programming tool. This might be a mobile device, a PC, or a console for specialised programming.

These are the primary parts of a conventional PLC, however depending on the PLC’s type and manufacturer, some of these parts may have different purposes.
