WEEK 6

On Thursday 7, we did a lot of things. There was the final day to do the daft and we were very bad. We had some problems when we started to connect the project with the PLC and the computer. There were 2 ways of doing that and with Profibus we couldn´t. We could comunicate with MPI but when we started to send all the bits and bytes, there was a big problem. Adrian and Unai were doing some exercises with MPI comunication, specifically X_GET and X_PUT comunication. It was a little bit difficult because they were a los of Inputs and Outputs and it was new for us. Aritz and Xabi were with the project. We had to comunicate 4 PLCs so we connected with MPI. We wasted too much time doing some exercises that anybody could do it.

On Friday 8, we did the second exam. It spend a lot of time doing the exam because they were different things to do. In the exam, we had to do 2 GRAFCET,  1 X_GET and X_PUT,  connect 2 PLCs and do a big program. It was a little bit difficult but we think that we are going to pass the exam with a good mark.

On Monday 11, we started with the presentations of the challenges, each group had to expose their work and explain what they had done during the three weeks of the challenge. We also had to talk about the problems that arose to us, and talk about how we got the solution. Then we went to each model, and we showed the work to the other classmates. Finally, the teacher came to each group to see if we had all the tasks done and completed correctly.


On Tuesday 12, today is the first day of the next challenge. we've started watching an introductory video about the program we're going to use during the challenge. That's what we've been willing to do the exercises on that program. One of them is to create a parking program for cars and pedestrians. Another of them is the filling of some bottles, another tries to perform the validation of bottles and apart from that place their respective labels and the final one, is about creating a program that would perform a machine to wash clothes.

On wednesday 13, we finished all the exercises of the new challenge, they were quite simple and we had practically no problem. On the other hand Professor Javi came and told us that we had to recover the PROFIBUS part of the previous challenge. Tomorrow we'll start with the model, investigating all the entrances and exits that have.
