PLC is acronym of Programmable Logic Controller is a digital computer used for industry automation that includes machineries, factory assembly lines, light fixtures, amusement rides, etc. PLC is used in many machines in all type of industries. This controller is designed for multiple arrangements, extended temperature ranges, analog inputs and outputs, resistance to vibration and immunity to electrical noise.
PLC is powered by a non-volatile memory to automate the industry process. Modern PLCs offer advanced functionality with motion management, method management, relay management and sophisticated networking. PLC monitors inputs and different variables like values, create selection and manages output to automate a machine or method. With PLC systems, SCADA (Supervisory Control and Data Acquisition) is used to remote control and monitoring that operates with coded signals over communication channels. Now, industries totally rely on industry automation, there is huge demand for PLC and Scada operators across the world. Taking PLC Scada Training in Chennai will ensure better prospects for talented professionals.
What is Industrial Automation?
Industrial automation is the use of various control devices like PLC’s/SCADA/VFD/HMI/DCS, used to have control on various operations of an industry without significant intervention from humans and to provide automatic control performance. In industries, control strategies use a set of technologies which are implemented to get the desired performance or output, making the automation system most essential for industries. Industrial automation involves usage of advanced control strategies like cascade controls, modern control hardware devices as PLC’s,sensors and other instruments for sensing the control variables, signal conditioning equipments to connect the signals to the control devices, drives and other significant final control devices, standalone computing systems, communication systems, alarming and HMI (Human Machine Interface) systems. Automation has been achieved by various means including mechanical, hydraulic, pneumatic, electrical, electronic and computers, usually in combination. Complicated systems, such as modern factories, airplanes and ships typically use all these combined techniques. Industrial engineers have envisioned fully automated factories since at least the middle of the 20th century. But the real race to automate manufacturing can be said to have begun in the 1980s, when US car manufacturers came up with the vision of “lights-out” manufacturing. The idea was to beat their rivals by automating the factories to such an extent that the entire manufacturing process could be left to robots. To a great extent, it has remained only a vision so far.
What is Industrial Automation in Manufacturing?
Industrial automation in manufacturing is the use of “intelligent” machines in factories so that manufacturing processes can be carried out with minimal human intervention. It involves the application of various control systems to enable operating equipment to carry out on their own, with little human intervention, tasks that require speed, endurance and precision. Industrial automation can be achieved by several different means, including mechanical, electrical, electronic, hydraulic, pneumatic, and computers. Usually, two or more of these means are used in combination. Today’s state-of-the-art factories, ships, and airplanes combine all of these techniques. The main benefits of manufacturing automation include leaner operation processes that require less energy, less material, and reduced labor waste. These can lead to improvements in quality, accuracy, and precision. Today’s industrial robots have high computing capabilities, vastly improved vision systems, and increasing operational degrees of freedom. However, they are limited to operating in highly structured environments and, to a large extent, still need to be controlled by humans. They are also too specialized and inflexible for the use of small and medium industries. Therefore, they can essentially be considered tools of long production runs and large manufacturers. With the rapid development and proliferation of microcomputer and software technologies, automation in manufacturing is almost totally dependent on the capabilities of computers and software to automate, optimize and integrate the various components of the manufacturing system. Due to this dependence, automation in manufacturing is called computer integrated manufacturing.
What is the Future of Industrial Automation?
Although industrial automation in manufacturing in not without its detractors (such as an unsubstantiated claim that it will lead to mass unemployment), its future looks very bright. Industrial robots of the future will be multi-functional so that the same machine can be put to several different uses. They will have many capabilities associated with human workers, such as the ability to make decisions and to work autonomously. They will also have self-diagnostic and predictive maintenance capabilities. Thanks to industrial automation of manufacturing, the factory of the future will be more efficient in the utilization of energy, raw material and human resources. Also, contrary to popular belief, the experience so far has shown that automation will not cause mass unemployment. On the contrary, the mass use of robots will create more jobs. Humans and robots will work together to create a more efficient and productive workspace.
