week12

We continued with the new challenge, first we started identifying all the outputs, inputs, presence sensor, cylinder end of careers and PLCs inputs and outputs.

 After doing that, we started investigating about MPI and PROFIBUS comunications, and we realized that the MPI connection was easier than PROFIBUS connection.So, to do MPI exercises we didn´t have any problems but to do PROFIBUS exercises we needed the help of the teachers.

We have a lot of problems with the PLCs comunication exercises because the funtioning of the PLCs are wrong. So when we started doing the PROFIBUS exercises at the beginning we thought we were going to finish the exercises quickly but we had many complications during the challenge.

We have divided into three groups, each doing the exercises and programming her project PLC.
Jon and Giancarlo did the MPI and X-GET and X-PUT exercises, Unai and Josu did some of PROFIBUS exercises and Alvaro did the rest of PROFIBUS exercises.

In this challenge we have to comunicate each button of each PLC with the rest of PLCs, and in our opinion this has not been an easy work.
