Hi Dev:
Thanks for your quick response. I really need that.
The following message is what I need you to verify and answer:
Attached is my first picture file that indicated two segment. One is some time that is before DAQmx read vi and the other part is 1/10 seconds inside the loop. Am my understanding correctly? That is what you were talking about in the paragraph above. Please verify me here
The acq i have posted will work for your PCI 6250.
In that VI, the virtual channels are configured,sample clock is set(these VI's two execute only once), the configured channels are scanned using DAQmx read continously inside the while loop and data is displayed every 1/10th of a second.
Here, you configure your channels and set ADC timing clock sequences just once and keep acquiring continously.
But in your old VI, you used to configure the channels and acquire from them on each loop iteration and that is not how continous acq should function.
That means the reason that takes time to count before the DAQmx read in my old VI is because I put the program in the timeout event case. The virtual channels need to configure each time of each loop and the acquiration of data is also need to take time. But in your vi, I don't need to take consideration of the time of the virtual channels and ADC timing clock because I set the parameters before I hit the run button in the program. Am my understanding correct?
What did you mean here? Did you mean that your program did not need to take count of the second before the DAQmx read vi. I don't understand. Could you pleas explain to me? Thanks
Yes, you do not have to programatically take count of second before each DAQmx read.
This is because, DAQmx Read will time itself and read data for a 1/10 sec period and update the data on the front panel after an interval of every 1/10 sec.
About adding a few more boolean buttons, yes you may add them but do take care of the program flow.
What do you mean? Do you mean I may add them in event structure. or case structure? Can you specify to me here directly? If the answer here is event structure, does it mean event structure is not necessay to apply everything in case structure feature. It is simply becasue of the example above that event structure can not take the time count out when executing the new program you gave me above.
Also, I would like to ask how come I can not turn the enable button on of my fixture using your program. I have already define the digital line on MAX, but it works on my sample I attached here, It did not work in your program. I don't understand why? What did I do wrong? Could you tell me please?
