strange result in fuzzy logic designer

[arjen.walstra]

i have never used any fuzzy logic functions of labview but for a new project i was told it might help.

The project involves controlling the temperature of a fluid through a peltier element which is controlled by a power supply.

I did some research on the internet and started playing with the 'fuzzy logic designer.

first i tried duplicating a video found on youtube. however the result of my configuration did not match the one from the video.

Than i tried making a very simple function which also didn't work.

Am i doing something wrong or is this a bug in the system?

I am using LV2016 64b (and also tried LV2015 32b) on a windows 7 machine.

to screenshot below show the single input and output variable and function as well as the result and 'test system'

I would expect to get a linear doubled output compared to the input.

But the 'test system' is showing something entirely different.

Thanks for the support,

arjen

We need to see your VIs (the actual files ending in .vi, not pictures of the Block Diagrams).  Is there a compelling reason to use 64-bit LabVIEW?  Are you working with really big (like GBs) sets of data?

If your code includes multiple VIs, compress the folder containing them and attach the resulting .zip file.

Hi Bob,

I haven't even started making the vi's yet. At this point I am only using the 'fuzzy logic designer' that gets installed along with labview. I have posted the front panels of the designer. 

I used to have lv2015 32b but "because I can" I now have lv2016 64b. Any reason why I should not use lv2016 64b? But that would be another discussion.

And the short answer (available by doing a Web search) is that not every Toolkit and Addon have 64-bit versions, nor are there as many 64-bit Drivers.

I haven't had issues so far for my applications. I tried the 'fuzzy logic designer' in my previous version of labview also (2015 32b) with the same result. Can I please get help for the original issue?
