“Automation” is a new word for new purpose. Ordinarily automation is any improvement in the control of some activity or process by non-human, i.e. automatic means, but sometimes the term being defined more narrowly. Recent steps in automation have followed each other with unusual speed. Many people are surprised to find out entire processes in industries like chemical and oil-refining to have become nearly automatic.

We now use the term automation for specific techniques combined to operate automatically in a complete system. These techniques are possible because of electronic devices, most of which have come into use in the last thirty years. They include program, action, sensing or feedback, decision, and control elements as components of a complete system.

The program elements determine what the system does and the step-by-step manner in which it works to produce the desired result. A program is step-by-step sequence that breaks a task into its individual parts. Some steps in an industrial automation program direct other parts of the system when and how to carry out their jobs.

The action elements are those which do the actual work. They may carry or convey materials to specific places at specific times or they may perform operations on the materials. The term mechanical handling device is also used for the action elements.

Perhaps the most important part of an automated system is sensing or feedback. Sensing devices automatically check on parts of the manufacturing process such as the thickness of a sheet of steel or paper. This is called feedback because the instruments return or feed back this information to the central system control.

The decision element is used to compare what is going on in the system with what should be going on, it receives information from the sensing devices and makes decisions necessary to maintain the system correctly. If some action is necessary the decision element can give instructions or commands to the system.

The control element consists of devices to carry out the commands of the decision element. There may be many kinds of devices: valves that open or close, switches that control the flow of electricity, or regulators that change the voltage in various machines; they make the necessary corrections or adjustments to keep the system in conformity with its program.

An industrial engineer working with automated system is part of a team. Many components of the system, such as the computers, are electronic devices so electronic engineers and technicians are also involved. Many of the industries in which automation has proved particularly suitable – chemicals, papermaking, metal processing – involve chemical processes, so there may be chemical engineers at work too. An industrial engineer with expertise in all these fields may become a systems engineer for automation projects thereby coordinating the activities of all the members of the team.

But automation has many sides. Electronic computers are becoming very good at routine clerical work in offices and factories. Transfer-machines in engineering, many kinds of machinery for making finished goods, mechanical equipment for handling and assembly – these machines do the actual work on their own; the operators only watch and correct them.

Automation can also mean automatic control of processes and machinery. Control is necessary in a vast number of processes to maintain the quality of a product when the operating conditions, such as temperature and pressure, change from time to time.
