Technological processes control automated systems
Automation is the use of control systems and information technologies to reduce the need for human work in the production of goods and services. In the scope of industrialization, automation is a step beyond mechanization. Whereas mechanization provided human operators with machinery to assist them with the muscular requirements of work, automation greatly decreases the need for human sensory and mental requirements as well. Automation plays an increasingly important role in the world economy and in daily experience.
Technological processes control with use of automated systems includes the solution of the following main objectives: processes` parameters control (temperature and pressure in the apparatuses, content and quality of liquids and gases, etc.); alarm system (warning, preventing) of the parameters` values deviation beyond the permissible limits; blocking (inhibiting) of improper equipment switching; equipment protection in emergency situations (switching off, the placement into a safe mode).
Production processes automation begins with the definition of problem which determines the level (degree) of the specific object automation, such as process installation. Hereby determines the direction of all future work, its scope and cost of expenditures, in particular, the acquisition and implementation of automation. The important thing in solving of the automation problem is the selection of the control system, i.e. determination of the degree of people's participation in the management, use of automatic devices, computer equipment.
Automation has had a notable impact in a wide range of industries beyond manufacturing. Telephone operators have been replaced largely by automated telephone switchboards and answering machines. Medical processes such as primary screening in electrocardiography or radiography and laboratory analysis of human genes, sera, cells, and tissues are carried out at greater speed and accuracy by automated systems. Automated teller machines have reduced the need for bank visits to obtain cash and carry out transactions. In general, automation much has been responsible for the shift in the world economy from industrial jobs to service jobs in the 20th and 21st centuries.

Automation
Automation is the system of manufacture performing certain tasks, previously done by people, by machines only. The sequences of operations are controlled automatically. The most familiar example of a highly automated system is an assembly plant for automobiles or other complex products. The term automation is also used to describe non-manufacturing systems in which automatic devices can operate independently of human control. Such devices as automatic pilots, automatic telephone equipment and automated control systems are used to perform various operations much faster and better than could be done by people.
Automated manufacturing had several steps in its development. Mechanization was the first step necessary in the development of automation. The simplification of work made it possible to design and build machines that resembled the motions of the worker. These specialized machines were motorized and they had better production efficiency. Industrial robots, originally designed only to perform simple tasks in environments dangerous to human workers, are now widely used to transfer, manipulate, and position both light and heavy work pieces performing all the functions of a transfer machine. In the 1920s the automobile industry for the first time used an integrated system of production. This method of production was adopted by most car manufacturers and became known as Detroit automation.
The feedback principle is used in all automatic-control mechanisms when machines have ability to correct themselves. The feedback principle has been used for centuries. An outstanding early example is the fly ball governor, invented in 1788 by James Watt to control the speed of the steam engine. The common household thermostat is another example of a feedback device.
Using feedback devices, machines can start, stop, speed up, slow down, count, inspect, test, compare and measure. These operations are commonly applied to a wide variety of production operations. Computers have greatly facilitated the use of feedback in manufacturing processes. Computers gave rise to the development of numerically controlled machines. The motions of these machines are controlled by punched paper or magnetic tapes. In numerically controlled machining centre, machine tools can perform several different machining operations. More recently, the introduction of microprocessors and computers have made possible the development of computer-aided design and computer-aided manufacture (CAD and CAM) technologies. When using these systems a designer draws a part and indicates its dimensions with the help of a mouse, light pen, or other input device.

Automation of processes
A process control or automation system is used to automatically control a process such as chemical, oil refineries, paper and pulp factories. The PAS often uses a network to interconnect sensors, controllers, operator terminals and actuators. The PAS is often based on open standards in contrast to a DCS (distributed control system), which is traditionally proprietary. However in recent times the PAS is considered to be more associated with SCADA systems. PAS is the lowest level of automation, while MES (manufacturing execution system) is considered to be directly positioned above a PAS. Process automation involves using computer technology and software engineering to help power plants and factories in industries as diverse as paper, mining and cement operate more efficiently and safely. Major blocks of PAS are: microprocessors, micro controllers and microcomputers, multiprocessors, LANs, SCADA, RTU (remote terminal units) and analog and digital I/O modules.
In the absence of process automation, plant operators have to physically monitor performance values and the quality of outputs to determine the best settings on which to run the production equipment. Maintenance is carried out at set intervals. It is generally results in operational inefficiency and unsafe operating conditions. Process automation simplifies it with the help of sensors at thousands of spots around the plant that collect data on temperatures, pressures, flows and so on. The information is stored and analyzed on the computer and the entire plant and each piece of production equipment can be monitored on a large screen in a control room. Plant operating settings are then automatically adjusted to achieve the optimum production. Plant operators can manually override the process automation systems when necessary.

Factory owners want their equipment to deliver the highest output with as little production cost as possible. In many industries including oil, gas and petrochemicals, energy costs can represent 30 to 50 percent of the total production cost. In process automation, the computer program uses measurements to show not only how the plant is working but to simulate different operating modes and find the optimal strategy for the plant. A unique characteristic of this software is its ability to "learn" and predict trends, helping speed up the response time to changing conditions. The software and controls regulate equipment to run at the optimum speed that requires the least energy. They also ensure the consistency of quality, meaning less energy is wasted producing products that turn out to be defective, and they forecast when maintenance is needed so less time and energy is spent stopping and restarting equipment for routine inspections.
