Automation

PLC

A programmable logic controller (PLC) or programmable controller is a digital computer used for automation of electromechanical processes. Unlike general-purpose computers, the PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed or non-volatile memory. A PLC is an example of a real time system since output results must be produced in response to input conditions within a bounded time.
The functionality of the PLC has evolved over the years to include sequential relay control, motion control, process control, distributed control systems and networking. The data handling, storage, processing power and communication capabilities of some modern PLCs are approximately equivalent to desktop computers. PLC-like programming combined with remote I/O hardware, allow a general-purpose desktop computer to overlap some PLCs in certain applications.

SCADA

Acronym for (supervisory control and data acquisition), a computer system for gathering and analyzing real time data. SCADA systems are used to monitor and control a plant or equipment in industries such as telecommunications, water and waste control, energy, oil and gas refining and transportation. A SCADA system gathers information, such as where a leak on a pipeline has occurred, transfers the information back to a central site, alerting the home station that the leak has occurred, carrying out necessary analysis and control, such as determining if the leak is critical, and displaying the information in a logical and organized fashion. SCADA systems can be relatively simple, such as one that monitors environmental conditions of a small office building, or incredibly complex, such as a system that monitors all the activity in a nuclear power plant or the activity of a municipal water system. SCADA systems were first used in the 1960s.

Industrial Robot

An industrial robot is officially defined as an automatically controlled, reprogrammable, multipurpose manipulator in three or more axis. The field of robotics may be more practically defined as the study, design and use of robot systems for manufacturing.

Typical applications of robots include welding, painting, assembly, pick and place, packaging and palletizing, product inspection, and testing, all accomplished with high endurance, speed, and precision.

Robots have been proven to deliver a host of benefits in a wide variety of applications. End users introducing robots to their production processes have typically Seen a significant transformation in their productivity and efficiency, with higher levels of Output, product quality and flexibility amongst the many improvements reported.

Machine Vision

Machine vision is the incorporation of computer vision into industrial manufacturing processes, although it does differ substantially from computer vision. In general, computer vision revolves around image processing. Machine vision, on the other hand, uses digital input and output to manipulate mechanical components. Devices that depend on machine vision are often found at work in product inspection, where they often use digital cameras or other forms of automated vision to perform tasks traditionally performed by a human operator. However, the way machine vision systems ‘see’ is quite different from human vision.

Hydraulic and Pneumatic

Hydraulics is a relatively new technology used in power transmission; which may be adapted to market requirements. The use of hydraulic drives, as well as hydraulic open loop & close loop control system has gained in importance in the field of automation. Nowadays it is unusual to find an automatic production procedure which does not include hydraulic components. As well as hydraulics, pneumatics played an important role as a technology in the performance of mechanical work. It is also used in the development of automation solution.
