Hi all this is my first attempt at the security system CLD practice exam. Would like some feedback on my solution please i have my exam booked for beginning of Feb. All comments to improve my solution are welcome.

Thanks

Hi Craig,

will you upload it as LV2012 version?

As Requested. Saved in LabVIEW 12.

I have a rather old description of this practice exam, but I hope we use the same version.

Your solution looks ok for me, I tried the functionality and it works as it should. On the real exam I would not spend time on implementing an error handler subVI, which is not requested. I think we should concentrate on realising the described functionality.

I plan to do my CLD in February/March, it was good to see your solution. Now I try to go through the core 3 material, but after that I will spam the forum with my own practice trials. 🙂

Generally not bad!  Now I'll pick on you a bit.

Panel sizing:  Really, its annoying to have really really big panels with lots of on-screen white-space.  Especially when you open them on a system with a single smaller monitor.  The VI Analizer has a test for that.  Make it happy.  Its only a style point but its a point off your exam.

"Code it once:"  in both loops you have identical code in multiple cases.  That should tell you you did something wrong.  How could you re-write those cases to combine them?  (HINT: in the event loop you even USE the Crtl Ref node!)

Your type def bool arrays did not make it into the project.  That is a good way to get broken arrows on code that you thought would work.

This is my attempt at the ATM, would appreciate any feedback.

I found this one really hard so didn't manage to complete the functionality, the vi that controls the deposit withdraw or fast cash was tested and worked, but i didnt get chance to implement them in the main vi.

Cheers

Jeff once again thanks for reply. I take onboard your comment regarding duplication of code! I could quite easily have reduced the event structure to a single case that minitores all off the swtiches, and then based on the CTRL REF called the correct state! Also the white space is something i need to work on i have a habbit of making the area large so i dont cram in the code. The type def Bool array i am uncertain on, i cant find it and didnt realise i made a type def bool array. Can you tell me the label of the control you are reffering to please jeff?

I am currently bombarding you with my solutions for all of the practice exams so thanks for all your help!

however the ATM example really is not that great!

Cheers

Craig
