XABI
This week we finished the 4 exercises that were presented to us, after finishing the 4th exercise where we had to program the function of a washing machine, Lander started the study of FIFO (First In First Out) and ATT while Gaizka and I began to program (TIA PORTAL) the model. First of all, we decided between the three to divide the model into 2 parts, the main part where the piece is fed by a cylinder and a suction arm will take you to where the piece is detected and differentiated by its color (Gray, Orange and Black). After the piece is measured by an analog output which we will transform through a block of Scale. and finally if it does not have the desired height it will be discarded and if it has the correct measurement it will be taken to the second part of the model. With the second part of the model we are just beginning but we anticipate that it has to do with FIFO and ATT.
In the subject of technical English, we just did an exam that contained several questions about our studies and for the next week we have to prepare a dialogue between 4 people, where 2 interpret the role of interviewers and 2 the role of interviewees.
GAIZKA
This week we have finished with the TIA PORTAL exercises and we have started with the model. On the one hand, Lander and I will begin to program and Xabi will start making the screen.
We have also had a written English test in which we had to answer about 10 questions. In general we believe that we have done quite well and for the part of the model we also believe that we are doing well on time.
LANDER
We have started the week finishing the third exercise. After that Xabi started we the fourth and last exercise while Gaizka and I started with the main program. First of all we tried to understand the proccess we had to program, and then we declared all the digital inputs and outputs. We realized that few sensors were failing so we changed them for new ones. During the rest of the week we programmed the first half of the proccess with automatic, semiautomatic and step by step modes.
I also investigated and learned how the FIFO works, to implement it in the program.
