Using LabVIEW algorithms on CTD test

[UnholyPenguin]

On my recent run of CTD, I got 18% because my LabVIEW algorithm didn't transfer to their tester.  On my side, I zipped and unzipped the code 4 times to make sure it worked...

My question is, has anyone successfully used LabVIEW code on the CTD test?  If so, how did you do it?

By LV algo, do you mean the drivers provided by NI to build the sequence?

[UnholyPenguin]

I mean an algorithm performed on the data retrieved from the simulated instruments.

You will be implementing all the logic in the Sequence itself. It should not depend on any user-developed external code.

Well, I guess I have A LOT to learn than 😅

Santo, do you have any advice for learning more TestStand syntax? Small practice tests like the CLD 1-18 practice cases?

I took the live training course and did the practice exam 5 times.  However, I found they did very little to teach me the complex TestStand algorithms that were needed for the real test.  I'm finding all TestStand resources to be deprecated/link down/host website down when researching old CTD practice questions.

CTD is straightforward compared to the requirements of CLD. On the other hand, on-the-job experience with TestStand will help you pass the exam rather than just the training or practice tests.

I think on the job I would use LabVIEW or Python to write algorithms. I thought TestStand was supposed to be a sequencer to plug-in algorithms from existing programming languages! 😅  I guess I'll go through forums and try to answer some community questions for practice

You're correct. In the scope of CTD, since the choice of programming language will vary, code module is provided out of box and the developer is expected to focus on using the existing code module in the sequence and thereby they can evaluate only the TestStand knowledge and not how you implement logic in the code module.
