It's not surprising to learn that the majority of the conveniences we take for granted are carried out through automated processing in a society that is always becoming more efficient. Machines are accomplishing crucial tasks including analyzing data, taking decisions, and cooperating with one another with little assistance from human operators.
Industrial automation has advanced, allowing systems like SCADA and parts like PLCs and HMIs to be combined to promote convenience, boost production, and enhance safety from potentially dangerous situations.
The SCADA systems and PLC that are used today in hundreds of important facilities virtually invariably feature HMIs. When it comes to processing automation and cutting-edge system designs, these procedures are essential. These systems will only become better. By 2024, it's anticipated that the use of SCADA would increase by over 7% as more firms switch to this more effective technique.
But while some of these systems share features and capabilities, it's crucial to understand how they vary and work especially for the demands of your sector.
A Quick Overview of HMI, PLC, and SCADA
SCADA systems are essential to the operation of industrial automation. These sophisticated systems can analyse data, store information, and carry out tasks without much help from humans, just like a computer.
HMI
A user interface or dashboard that enables human interaction with a machine is known as a human-machine interface. HMIs are utilised in a variety of technologies across the world, from power plants to cellphones.
HMIs are used for human-machine interaction but are not a component of any one piece of software.
- Screens
- Buttons
- Levers
- Computer mouse
- Keyboards
SCADA systems can operate without an HMI, but it is frequently advised. The operator will be able to interact with the system effectively and will be informed of any errors that require attention.
PLC
A programmable logic controller is frequently referred to as a mini-computer that can interact with many devices, equipment, and systems. They are essential parts of SCADA since they are made to control and troubleshoot networks.
This system is utilised for any circumstance that demands high-reliability control by a human operator and simplifies machine operation while simultaneously offering required functionality. Additionally, they are a crucial component of industrial automation, and SCADA systems would not be able to work without them.
The primary functions of PLCs within SCADA include:
- Robots
- Assembly lines
- Counters
- Measurements
- Calculations
- Sensors
- Motors
- Lights
- Fans
- Circuit breakers
SCADA
SCADA, also known as supervisory control and data acquisition, is an automated control method that many big sectors, including manufacturing, construction, and engineering facilities, employ for industrial automation.
A SCADA system consists of two parts:
- PLC (programmable logic control)
- RTU (remote terminal unit)
Human-machine interface (HMI) is a distinct element that is frequently included with SCADA. SCADA is a system that combines hardware and software components to manage interactions, monitor and record data, and control activities using PLCs and HMIs.
The Important Role of Industrial Automation
Utilising several control systems to operate machinery and equipment is known as industrial automation. This varies greatly across various businesses, including factories that produce goods and control systems for structures, transportation, and communication.
This kind of high-functioning procedure employs machines and computers to take the place of humans in the work force and requires little supervision from the human operator. As a result, the following are some of the key benefits of an automated system:
- increased productivity as a result of machines' continuous operation
- Increasing product quality while maintaining the same output each time
- lower labour costs by using automation in place of people
- reduced regular inspections thanks to PLC and Human-machine interface (HMI) cooperation
- raises the degree of safety by removing personnel from potentially dangerous areas
In the end, automation is a great approach to complete important tasks with little assistance from humans. And despite being applied in many ways, this technique has been used by people for generations.
A Brief History of Automation
Over the following many centuries, people continued to develop methods for simplifying labour. There were several methods to make living more practical, including gathering food, constructing homes, and the advent of the Industrial Revolution. Furnaces, engines, and temperature regulators were among the earliest self-contained machinery that people used in the 1800s.
Industrial automation accelerated as the 20th century rolled around and people began to use electricity more often. Industrial automation, which was a little more complicated than the automation people had been accustomed to for years, was the control and utilisation of multiple systems to operate equipment like machines. Products, supplies, and essentials like transportation and energy generation are in great demand nowadays. Utilising industrial automation is one of the simplest methods to satisfy these expectations. These comprehensive systems aid in the control of these important aspects of daily life, all of which need for efficient systems like SCADA, PLCs, and HMIs.
How Do HMI, PLC, and SCADA Connect in Industrial Automation?
There is a lot of technology to keep up with in today's environment. Therefore, even though it may seem difficult to comprehend the precise workings of complicated systems like SCADA, it is a simple chain of information. Keep in mind that SCADA systems are designed to:
- Automate processes and procedures
- Track and analyse data and errors
- Perform remote site monitoring
- Increase productivity and guarantee same-quality outputs
The easiest way to think of SCADA is as the central database that houses and manages all of your activities. The system works and communicates within the operating environment thanks to this communication with the PLC. The SCADA-PLC system may have an HMI, which might be in the form of a screen, buttons, levers, or a keyboard, allowing people to interact with it. Machines used in factories, computers, and automobiles are a few examples.
HMIs play a crucial role in providing information to the operator in industrial manufacturing. Any problems with the SCADA system may be found by the PLC system, which then presents them to the human operator through the HMI so they can be corrected.
Manufacturing Facilities
Automation systems are used in several sectors, but some of the more well-known ones include:
- Cattle, grains, fruit and vegetable preserves, and packaging are examples of food.
- bottled water, soda, beer, cigarettes, and cigars are examples of beverages and tobacco.
- textiles, such as cloth for clothing, bedding, towels, curtains, and other items
- Products made of wood, such as timber, plywood, veneer, flooring, and building supplies
We can safely conclude that there is a global need for commodities, which also implies that productivity requirements are higher than ever. Manufacturing facilities use industrial automation technologies, which boost productivity and reliably generate high-quality goods, to assist fulfil these expectations.
Power Production
There is a critical need for autonomous power production as global energy consumption rises continuously. The distribution of output is greatly increased by automation systems like SCADA, despite the fact that these facilities need human operators.
Food and Retail
If you've recently visited a McDonald's fast food restaurant, you might have noticed a new feature: an ordering kiosk. Productivity is increased with this computerized touch screen ordering system, which results in less waiting for customers and more time for workers to concentrate on their jobs.
But automated systems aren't just used by McDonald's. You may come across instances of these methods at any particular eatery or grocery store, such as:
- Conveyor belt systems
- Online shopping options
- Self-checkout machines
- Drone deliveries
Automatic banking is yet another excellent example of SCADA systems in the retail sector. People may withdraw money from their checking accounts at any time thanks to ATMs. These systems collaborate via SCADA, PLCs, and HMIs.
Conclusion
The world of work is changing as a result of industrial automation. Machines can now operate and process data faster than ever before, increasing production consistency while reducing labour expenses and labor time.
