system configuration settings

[bigred]

Recently I lost my system configuration for running DAQ and had to copy the cofig from another system with DAQ to open my data acquisition. However I always have to have the disk in the computer to run. How can I save the config from the disk to the system so that I do not need the disk anymore? Also one of my systems uses a switching valve controlled by labview and compared to other systems this one is slower to switch the valve (I can say MISSISSIPPI before it switches). The valve itself is fine. I have always had problems with this system (crumby baseline, etc.) Can anyone help? Thanks

Hello bigred,

Take a look at your disk and see if there is a file in it called niconfig.daq. This is your daq configuration file. Copy this file into any location on your hard drive. Then open up Measurement and Automation Explorer (MAX) and select Tools on the menu bar. From here, select Traditional NI-DAQ Configuration and then Set Active Configuration. Then navigate to the folder that you copied niconfig.daq to and double-click on it. This should set your DAQ configuration to the settings saved in that file without further need of the floppy disk.

I would need to know more about your system before I could really say what is causing the slowdown in valve switching. What type of DAQ board are you using? Have you tried testing it in MAX? If the slowd
own occurs there as well, then the problem is likely in device configuration or hardware. Otherwise, the slowdown is more likely caused by software, i.e. the LabVIEW code.

When you say that it switches faster on other systems, is that when running the same LabVIEW code with the same DAQ hardware? If so, there may be some other hardware considerations involved. Does one system have more memory or a faster processor than the other? Either factor could cause faster execution of code.

What kinds of VIs are you using in the code? Certain VIs may run slower than others.

Let me know if you have any further questions on the configuration question. For your valve switching question, I would need to know more particulars about that setup and the code.
