Introduction

Good afternoon guys and teacher, my workmate is Monica and me. I’m Javier.

We are engineer and actually we are working in the company “Meat market”. We are responsible of the area of machines, so the company want to automate the transport of meat, for that we desing a solution and investigated a pair of teams of PLC’s.

Well, first we are going to explain who is a PLC?

It’s a computer used in the automated engineering to automate differents process into industry.

For example:

Packaging aplications Food and drinks Pharmaceutical Contol cluten/broke

This teams were selected according our needs.

For that we studied the number of motors to control
