Sample Exam Solutions for Review

[J_M_M]

Thanks for the detailed feedback. I am still struggling with the wires, but I hope to get better at it after more practice. Thanks for your advice on the documentation, I did not think about putting details on each state; I read it so many times that it was embedded in my brain. I will keep that in mind for the test and also to add the tip strips for the controllers in the front panel. 

Thanks again!

Hello,

I have completed some CLD practice exams and the CLD16 example

It would great if I can get some comments on the solutions

(Car wash example, Stop commands does not initiate immidiately on press if the card is in position and the design is running since the Enqueue element at opposite end, enqueues the current state if the timer did not elapse)

The Car wash and ATM exam took around 3 hours to finish, I am currently working on the remaining samples, What should I expect in the CLD exam as difficulty and complexity versus the samples?

I found the samples to be extremely relevant to the real thing.

You've fallen into the same trap a lot of people have here.  You need to put all your stuff into projects!  At first I wondered why so many people did not do this, but then I realize that there is no mention of it anywhere in the instructions.  I believe this is because the project is already started for you in the real test.

I can't see your code because I don't have that version of LabVIEW, but I can see that there are no project files.  Put your stuff into projects and re-upload.

Hello,

I have re-uploaded the solutions in a project heirarchy and included a 2014 save (I am working on a 2015 version)

Thank you

Some inital thoughts:

• Pay more attention to wiring.  Too many unnecessary bends in the wires costs you easy style points.
• Use tip strips for your controls.
• You don't need to "Quit LabVIEW".
• In the wash count.vi, you forgot to at least wire error in to error out.  I know this was an oversight and not your coding practice, but I had to mention it.

• You used subVIs.
  • Furthermore, you gave the subVIs descriptions.
• You gave your main VI an icon.  (I had to drill it into my head to remember to do that; I kept forgetting.)
• You labeled your wires.
• You made use of the linked input tunnel.
• Documentation was adequate.  (Except for the tip strips.)
• It works.

I'm too tired to give this a proper shakedown, but this is what I have so far.  I hope it helps.  🙂

Dear All,

Thanks for all the valuable feedback, it does help in improving the coding.

I have finished the Car Wash sample exam and I would appreciate your feedback on it. I tried my best to avoid crossing wire, but it is quite dificult to avoid them all in just 4 hours. I tried using SubVIs to organize them and it works, but I did not want to create a subVI for every crossing wire.

Anyways, your feedback would be much appreciate it.

Best Regards,

JMM

Thank you!

That is helpful, I was working on further improving my coding speed

and style

Dear ghattas.ak,

I was having a quick look at you car wash sample exam and I realized that it was utilizing almost 100% of my CPU, then I noticed that you did not add any wait function on your second while loop. Just keep that in mind for the exam. Also, your timer subVI has the error terminals but they are not connected to anything.

The rest of the program looks good and it is easy to follow. The "Quit Labview" was kind of too much, but it does not hurt to have it if times allows it.
