Programmable logic controller (PLC)

A programmable logic controller (PLC) or programmable controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, control of amusement rides, or control of lighting fixtures. PLCs are used in many different industries and machines such as packaging and semiconductor machines. 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, otherwise unintended operation will result. This small controller, is the life in the industry because it is the charge to controll all the process there, through a progam language.

About the IEEE Foundation

Bringing the exhilaration of scientific discovery to students, fostering technological innovation, preserving history, promoting public awareness of the long-reaching effects of engineering - these are some of the important functions of the IEEE that are supported by the work of the IEEE Foundation - the philanthropic arm of the IEEE (Institute of Electrical and Electronics Engineers, Inc.).

With contributions from generous sponsors around the world, the IEEE Foundation seeks to increase the understanding of how technologies are created and how they impact society, individuals, and the environment. Interdisciplinary in its activities, and transnational in scope, the IEEE Foundation has the potential to improve people's lives in every country.
We invite you to explore these web pages to learn more about the IEEE Foundation, and how you can help us to help you make a difference.

Exhilaration: great happiness, excitement

Awareness: First stage in the process of learning about a new product, service, or idea in which the consumer has received information about the existence of the innovation but has not yet formed an opinion.

Philanthropic: Organized to provide humanitarian or charitable asístanse.

Sponsors: One that finances a project or an event carried out by another person or group, especially a business enterprise that pays for radio or television programming in return for advertising time.

Seeks: To try to locate or discover; search for.

Environment: The totality of circumstances surrounding an organism or group of organisms.

Scope: The range of one's perceptions, thoughts, or actions.

My Interview...!

1. Could you please define Engineering in your own words?

Is a science that applies scientific knowledge to invent, to refine and use it in favor of the humanity.

2. What influenced you to pursue Electronics engineering, industrial engineering, computer science engineering or informatics engineering?

I chose electronic engineering because I wanted learn about the sistems desing, also I like numbers and circuits.

3. Could you please describe the educational process required to become an Engineer?

First, A good engineer must have knowledge about maths, physics, desings, prodution and control of process. After must have creativity and dedication.

4. What are the skills you need to be a good engineer?

The skills that a engineer must have are the hability and fast for solve problems, work in group, to be focus in his goals, have a rutine disciplinary and to have imagination.

5. What job considerations were you looking for after you completed your education?

I would to work in a private company, in the control area.

6. What's something of your school life that you enjoy the most?

I enjoyed much in my school life to be my friends and go out with them.

7. From your perspective, what is the most difficult part of being an engineering student?

For be a engineer, you have to be very dedicated and study hard. If you dont like the engineering you sould not study it.

8. What are your plans for the future?

Graduate me and find a job.

9. Point out your most personally gratifying moment in engineering school.

When I have good grades is a good moment.
