Assembly line control

Abstract

Basically we have three automatic systems that collaborate to build the final product which is a plastic pot with some kind of a liquid inside placed in a carton box. At the beginning machines didn´t work properly so we wrote new programs for each one. Writing a new code imply to know how the machine works in a more specific way, so imply to know where are all the sensors, where are all the valves, how the robots are working with the pressure, etc. It is also necessary to know that all the machines have their own address linked with the PLC register in order to allow PLC and system to communicate in the right way. In this case all the parts are already named with a label so we can easily recognize all the symbols in the software. To create a scheme of processes, which is very important for writing the code, we will use grafcet.
