Are you sure you want to use the built-in function for the cold junction compensation?
what's that RAY ?
You should do a search on this forum
Also, are you sure you are using "T" type thermocouples? The usual ones are K & J types..
Well the one I had T and was working so it is T
I saw different problems :
the stop button is doin the same thing as pause button. I want a stop button to reset the graph and all states to the default one....so the user can take another Test .
You didn't mention that in your problem statement... So it is not a problem, it is a lack of definition 😉
Here's your original request (post 1). You have to be specific.. 😉
Hi Guys , Just wondering how to add a stop button to reset my program without exiting.
I
have 3 buttons , 1-Start 2-Pause(it pauses the data collected but once
i hit start again , it will continue on the same graph and same output
file) 3-Exit (this exit the whole program) .
How can I add a stop(more likely as reset) button to collect a new data without exiting the program ?
I know it is something to do with the inner loop.
Thank you
i also found out that when i use another Daq refresh rate , the vi freezes up , it works only fine with 500ms .
I would also love to have the user enable the channels after running the programe , not before 🙂 as i had it in my last VI......
I didn't try the other rates, but they are likely so slow that it "feels" like it is frozen (although the weather is not helping :D)
I can look at that on the weekend..
Why dont we use the VI I had and just add stop button to reset every thing to default (to do another test) , or the architecure i have does not allow that ?
THe architecture would not allow the other feature about clearing the graphs... This architecture is scalable, meaning you can add to it. Plus, how well did the original one work? And why would you want to revert (step back) to the older code??
this is what NI eng suggested :
However, I noticed that you have an empty case in the Case Structure that executes when the "Start Button" is not selected. You can design your application so that it will reset when the "Start Button" is not selected, and develop your resetting code in the False case of the Case Structure. If you want to proceed this way I suggest you do the following:
- In the False case of the case structure have the same property nodes and constants that you use in the structure "Reinitialize to Default". With doing that, when the Start Button is not selected, the Physical Channels, Daq Rate, File Path and Waveform Chart indicators will be cleared. I understand that’s what you want performed when you say you want it to reset.
With this suggestion, you don’t need to implement a new "Reset" button and the logic about it to manipulate the while loops. I’m suggesting this due to your time constraints. Please let me know if this is helpful or if you have other specific questions related to this issue.
So Ray what do u think ?
He may have wanted to preserve your architecture. I wouldn't recommend it.
