Industrial automation systems designed to solve several tasks at once – improve product quality, reduce its cost, and solve the issues of industrial safety. Such systems are built to meet the specific technological processes, and consist of elements that can be divided into tracking, analyzing and controlling, and executing. Tracking elements are usually different kinds of sensors that provide analyzing the possibility of automation have an idea of the different indicators of the process, and timely respond to them. Examples are familiar to us in everyday life temperature sensors, sensors of linear and Angular displacement sensors, level measurement of liquids and solids. Actuators work out the command control unit, making some adjustments in the process – move workers bodies and other items of equipment, control the temperature in the working area, enables or disables the flow of process liquids, and solve even a huge number of industrial applications. Analyzing and controlling elements of the automated line monitoring the process and make adjustments to it. In the simplest case, such systems are different kinds of relays and automation for such a system – the name is rather relative – make changes in production technology, as this usually entailed major changes in the design of the control unit, or require a very complicated and precise adjustments and readjustments. Sophisticated control systems are based on microprocessors and computers, which allows you to make changes in the processes by simply changing the control program. Formed in this way automation of production almost needs no direct human intervention in the production process, allowing people to use only as operators, looking for indications of control devices and the progress of the process, and adjusters – to replace worn-out tools, maintenance and repair of the production line..
