WEEK 16

Once finished programming the whole process, we had to start with the screen.

First we had to put all the inputs and outputs in the memories of the screen,
and this was something that cost us a lot to do and we lost a lot of time.

Then we had to connect the project lights to the screen to display the alarms,
it was an easy job.

When we had the screen programmed, we had to connect and communicate with all
the PLCs and check that everything was correct, but we did not empty the project
and we had to reprogram the screen.

We tried it again and everything worked correctly and since the exercises of the previous challenge were poorly delivered, we have started to do them again and prepare for the recovery test that we have next Tuesday.

The teacher has given us some review exercises and as we hace some problems, we to come in the afternoons after working in the company.

WEEK 15

The model we are programming works when a sensor detects a piece, and when it detects it, it causes a cylinder to exit and move the piece forward. When the piece hits an end of the race, it causes an arm to search for the piece, sucks the piece, and then moves it to the right.

Through 3 sensors, we say what color the piece is, whether it is metal, orange or black.
if the piece is black, another cylinder pushes it.
If the piece is orange, lift the elevator, and using an analog sensor, say if the piece is small, medium or large.

If the piece is large or small, you have to lower the elevator and eject them as if they were bad.

If the piece is medium, when the elevator is up it pushes the cylinder, and takes it to a rotating plate.

After it reaches the drill, it is activated, then it will arrive at the stamping and later, a cylinder take the piece and classify the piece in two different places, depending on whether it is orange or metal.

It has a button (P1) that we have said that activates the process, and also contains a button 2 (P2) that resets the entire program and an emergency mushroom, which stops the entire installation.

Week 14

We have to continue with the last long exercise because we can't start doing and programmimg the project since finish correctly all the exercises.

So, to do this exercise, to do this exercise we had to  the work together whole group and divide different parts of the last exercise.

Josu and Álvaro did the grafcet and program of the first PLC, Unai checked all the inputs and outputs of this exercise and Giancarlo and Jon did the same of Josu and Álvaro but with the second PLC.

Josu and Álvaro had a lot of problems with the resets of all the states of the program but Giancarlo and Jon didnt have any problems because their PLC program was shorter and easier.

When arrived the our to put un common the three parts of the exercise we didn't have problems because the works were be done right, so It has been an easy work.

Once the last exercise was finished we started with the maquet we had raised in the challenge and we had to do the same, divide the work into three parts.

How Unai worked correctly identifying the inputs and outputs we decided together that it can be her work.

Josu and Álvaro programmed two short PLC programms and Jon and Giancarlo started programming the most difficult PLC program with analogics inputs.
