CLD Exam

[ade77]

I want to take the CLD exam, and I am still having problems even with the sample CLD exams.

Any suggestions on how I can improve my knowledge to that level.

There are no text available for an intermediate user.

Thank you.

NI offers a LabVIEW Intermidiate course.  It covers some items that you would use in the CLD exam.  I highly recommend it.  This intermediate course is more advanced than the intermediate courses of old.  It offers a wealth of knowledge on such things as state machine architectures, producer-consumer architectures, use of references, designing user interfaces, VI performance, communications such as TCP/IP, shared libraries, VI server, and Active X.  If you can't afford the class, I believe you can purchase the training materials.

I would also recommend looking at and evaluating the examples posted by the more advance users on this board, go to lavag.org, and review the materials there. Remember, if it were easy what would be the value? Good luck

hi

i am planning to take CLD next jan(6 months more)how to prepare so tat i get through cld.i am a student workin with labview at college level.i cant afford intermediate training program.can someone give tips to get self trained efficiently.which part should i concentrate more .it would be of great help because i want a career in labview

thanks in advance

I would highly recommend getting the training first.  Otherwise, you need lots of experience and reading many of the posts in this forum. A good place is to look at the Rube Goldberg thread in the Breakpoint forum.

You need to know all the different ways of commenting your code, as well as to be almost intimate with the various architectures (State Machine & Event Structure).  You must be able to code WITHOUT using a single local variable, know where & when to use the shift registers, avoid Globals, probably knowing Action Engines is a good idea (Functional Globals)..

what else...  oh yeah..  be verfy familiar with the Functions and Controls palettes.  and be relatively quick at programming in Labview.

Curious:  how much experience do you have so far with Labview?  Can you post examples of your coding experience?

On a similar note (Some thread-hijacking involved, sorry )

I have only recently been asked for the first time ever if I have any NI qualification....... (Which I don't, I've never been to a course)

How hard is the CLD exam?  I've heard people saying it's kind of strictly on NI's view of things, with some answers being debatable on forums like this one......

What to the resident CLDs think?

The things that worry me about the CLD exam are:
1) 90% of my work is done with LV7.1, and 6.02.  8.0 is the highest version I've even seen.
2)My company couldn't give a rat's @5$ about certification so it'll be on my own dime.  I'd hate to pay and not pass!

From what I've read, a lot of it is about design style.  Building an application that is maintainable and scalable etc., but the changes that came in with 8.0 (projects etc.) have not been insignificant.  I think I will need tio sit on my CLAD for a little while

hi joe,

well u ve asked about my programming knowledge.its in the incipient stage and im working on it.i am familiarising with loops and arrays.looks like  cld needs lot of hard work n time(worth spending).i will think about the training prog.can u mention some small programs tat i can try out.so tat it will be a sort of  practice for me.

thank u

The project isn't really important for the CLD.
The main differences you will notice during CLD are the changes in palettes. So download an evalution copy of LabVIEW and just use it get at comfort with the palettes.


My experience:
2 hour of programming
1.5 hour of documenting
0.5 hour of fine tuning.

I did my CLD with 96 points. A colleague didn't finish the CLD BUT he had all the placeholders for pieces of code and he passed (just), thinking ahead is very important.

Get customized with state machines.

CLD is worth it's money,  it forces you to rethink your strategies towards building code (and even thinking about how you code is always a plus).
The intermediate I took 2 years ago was quite comprehensive, I really really learned a lot about queued driven state machines.

Yes,
in the past 6 months I have spent a lot of time fixing old code written both by myself and other folks who have no training in LV, just experience.  God, the nested case structures!  It is amazing to me to look at the difference in two programs (the before and after) when one of those nested bastards is properly modularized and turned into a state machine.  They are so easy to navigate and see what is going on.  It is now maintainable!  I hate to think about how many of those abominations I wrote before I learned the proper way to program in LV.

I thought that I had read about people having trouble with their older LV installs after removing the evaluation copy.
