Industrial Automation and its Classification
Overview
Think that you have a low level or mid-level industry and you want to control and maintain some main panel from your desk. You have to do it without going the main point physically. Now think that you want to run some specific machine and motor continuously and unconditionally day by day. How this thing possible to do that?
It is very much possible with the help of Industrial Automation. To make industrial automation, there is a need for some electrical devices. These are the PLC, HMI, VFD/Inverter, SCADA, etc. To make a system automatic, these all the devices are essential.
In the field of industrial automation, plc mainly electronics-based small computers. The working principle of this plc is that it is basically monitored and checked the device. It also produces output based on custom program, that custom program which is set by the user.
If we say about HMI in the sense of industrial automation, HMI (human-machine interface) is a user interface that interacts with an operator or person with the machine, computer to the controller for an industrial system. The human-machine interface mainly consists of hardware and software. The software of the human-machine interface allows user input that user inputs later translated as signals for machines. That is providing the required result to the user.
Now lets some talk about variable frequency driver in the field of industrial automation. Variable frequency drive or inverter is a kind of electronic device that, it is basically used in the industry and factory for the purpose of controlling machine. VFD can control the machine with varying frequency and voltage level.

Industrial Automation
Industrial automation is a kind of device control system, such as computers or robots, and information technologies, for maintaining and handling different kinds of processes and equipment in an industry to replace a human being. In these modern days, the industrial automation market, for industrial framework developers to successfully address ever-evolving challenges, new technology brings many opportunities.
To that of human thinking industrial automation is the system of replacement with computers and machines. The automation word means that self dictating or a mechanism move by itself. That is derived by the Greek word, Auto and Matos, where Auto means self and Matos means moving.
Industrial automation also mentioned as the use of readymade technologies and automatic control devices that gives output the automatic operation and maintenance of industrial processes without significant human interfere and achieving upper performance than manual control or maintenance. These industrial automation devices include PLCs, VFDs, PCs, PACs, HMI, SCADA systems, etc. There are also many technologies that include various industrial communication systems.
Benefits of Industrial Automation
Due to the favor grant by the integration of industrial automation technology- adding improved the rate of production speeds, finest quality control, and development safety. A developing amount of manufacturing facilities across morally every industry is opting to adopt it over traditional manual or manual systems. Below given some of the important benefits:
Developing in Manufacturing Quality and its Production Efficiency
To make a manufacturing company superior in their market, they have to produce better quality products. They have to reduce the overall production error rate. The computerized manufacturing and assembly materials, such as CNC machines, programmable logic controllers, variable frequency driver, human-machine interface, supervisory control, and data acquisition, etc. these are actually making programs arrangements to control repetitive tasks with developing small error rates.
Also, these materials or equipment have the ability to instantly execute new operations and additional steps in an assembly process.
Increasing the Production Rate
If you compared with human-operated facilities with automated manufacturing facilities, automated manufacturing facilities offers faster and continuous production capabilities without the risk of errors. In spite of the fact that modern automation despite everything needs some labor for assessments and oversight, robotized forms have a more noteworthy profitability rate per individual in the assembling region than mechanical procedures.
Reduced Costs
The industrial automation system reduces the costs of industry, factory, etc. To make the system automated; there is needed less maintenance than the human operating system.
Safety
Automatically processes are safer than human operating machines. Automated process safer, because it requires less operator involvement. It is better than taking on the role of the operator; human supervisors are able to monitor tasks and production from a safer distance. While the machine can handle the tasks dynamically.
Reduce Routine Checks
In the automation system, human or user can set time for whole day operations. Such as starting time, closing time, and etc. That means, there is no need to check every time what is going on, when it needs to stop, etc.
Classification of Industrial Automation
Industrial Automation system can be classified into three types:
- Fixed Automation
- Programmable automation
- Flexible Automation
Fixed Automation
Fixed automation systems, or “hard automation,” are ordinarily utilized for production systems with solely assigned equipment and high-production needs. The equipment in a fixed automation system is made and intended to perform just one lot of procedures on one section with significant levels of proficiency. Fixed automation systems have applications in both consistent stream systems and discrete large scale manufacturing systems. These systems work with reason constructed machine equipment that does monotonous, fixed procedures to arrive at high-volume production objectives.
In fixed automation, the arrangements and sorts of tasks permitted by the setup of the equipment are limited and preset. Wiring, cams, gears and other equipment convey the modified guidelines that fixed automation machines follow in the production procedure. These systems will, in general, assembling a similar item style, and they are planned such that makes changing item styles troublesome. In spite of it’s at first high speculation costs, a fixed automation system is appropriate for high volume production forms where items tend not to change a lot after some time. This considers the greater expense of fixed automation system plan and development to be extended where systems can be altogether amortized sometime before production stops.
Programmable Automation
Programmable automation takes into consideration machine designs and activity sequences that can change dependent on signals sent from electronic controls. With a programmable automation framework, products can be created in groups through the reinventing of machine tasks and sequences. The products made right now are bunch amounts, and these groups can be as low as only two or three dozen products and as high as a large number of units delivered at once.
At whatever point another item clump is required, the programmable automation gear can be changed and reconstructed to deal with the new and distinctive item types. The mechanized creation line process can’t proceed while the reinventing and changeover forms are happening. After these changes, the creation of another sort of group runs.
Flexible Automation
Adaptable automation systems are exceptionally versatile systems with computer info and controls. Directions are made and entered by human administrators utilizing computer code or through other Human Machine Interfaces (HMIs). These computer instructions are a significant level, beginning low-level changes naturally and recognizing different automation forms and their system areas. Firm automation systems, different machine apparatuses can be associated with advanced material-taking care of system ordinarily through mechanical automation. Every part of the creation and material-dealing with the system is controlled from a focal computer system.
In the adaptable automation system process, computers constrained by human administrators issue instructions to machine devices. These computer-created instructions start procedures of stacking and emptying the machine apparatuses that are important for playing out the procedures important to make the ideal parts. After the creation automation system completes its last assembling stage, the subsequent items are moved to the following machine in the arrangement naturally.
