SECOND WEEK

We worked this week in the comunication of two PLC in TIA PORTAL V13. We finally comunicated both PLCs. It cost a lot of effort and time. We also had some different problems. First, we could't control the air system because the controller is broken and there wasn't a reclacement, so when the mechanical arm take the piece and move it to the tape, it did it very strongly and that caused that sometimes the tape's motor stopped.

Also the robot didn't worked and we couldn't introduce it in the challenge. It was a little bit disapointing. The robot looked the coolest thing of the challenge and we were enthusiastic about using it. Now we barely now about programming and using a Mitsubishi robot. We tried to start making the exercises but they were vey difficult and the didn't have enough time to finish all.

Another problem was that we didn't have the enough sensors to detect black and red pieces. So the detector we had it, we use it to the black piece and for the red pieces, we made an input on the PLC and the openened the barrier activating a switch.

We also had problem with the cables and tubes. The cables weren't numbered and we didn't know where the were conected. Some tubes were also wrong conected to the solenoid valve and because of that, the system didn't work at the beginning.

We also had to move the ramp where the pieces end because when they were on the tape and the barrier threw, they didn't fall correctly so we had to move it.

There were some problems but we did some things right. The camera worked perfectly and we learnt a lot about the In-Sight camera program. We also finished all the camera exercises because the were very easy except last exercise, it was so difficult that even the teachers didn't know how to do it.

We also made the screen for the mounting, the screen was easy to make it but we didn't have the enough time to finished like we want to.

Finally we presented the challenge to the teacher and he decided to approve the challenge or not. We were lucky because we didn't make any exam but we will make it in the rest of the challenges.
We also made a presentation in front of the class and we also made a demostration of the mounting.
