WEEK 4

On Thursday 24, we did an English exam, and we hope to have a nice exam grade. Unai and Adrian had work hard for this exam, because their English is not the best one. We continued texting if all the models we programmed before, were working correctly, and yes they were. Also we had been investigating about the OB100, that is a startup. ¿What does this mean? It is a program that only launches once (at the beginning), when we start the process. Finally we finished the day investigating about the MPI comunications.




On Friday 25, we started with comunications exercises, but it had been a fail. We didn't understand it very well and we also didn't know how to do it. But finally, we started doing the organization chart of all the models, and we finished two of them. Aritz, continued with the OB100, and he finished but we didn't know if it runs correctly, because sometimes it didn't launch at the beginning. Finally,we tried to connect the models with a PROFIBUS connection.

On Monday 28, we had continued with comunications exercises, and we also finished the organization chart of the third model, so there is one more left. Andoni started with the HMI, but we discovered, that we didn't have the license to connect it to the computer or to the models. We were having a lot of issues to connect the computer with the PLC's and this had delayed us a long time. Also, we have to mention that some cables, that we use to the MPI connection, they don't run correctly.

On Tuesday 29, we had continued with comunications exercises, but we were starting to find difficulties, we didn't think that it would be so difficult and that we didn't going to need so many time, but hopefully we are learning a lot in this challenge. We also saw a fail in the model 0. We will comunicate to Andoni to check it, because is his model. We have finished the first exercise of comunications. In the last hour, Adrian, Xabier, and Unai had been writing the blog of the previous days, while Aritz and Andoni went to dual.




On Wednesday 30, we have been doing other comunications exercises. Adrian, Xabier, and Unai have been doing the Global Dates, donde they have had a lot of problems, so they didn't finish it. Andoni and Aritz have been connecting two models through PROFIBUS connection, but unfortunately they didn't get it. Tomorrow we will see the English exams.
