Question: I am currently encountering Hard Drive Memory space issue to store file on a National Instruments based CDAQ Tester. I am using Labview 2013 SP1 and have to all the software load in the CDAQ Controller. Some of the basic specifications for the CDAQ are as follows

  • Processor: Intel Atom 1.33GHz Dual Core
  • Controller OS: Windows Embedded Standard 7
  • Hard Drive Memory Size: 16 GB
  • Number of Slots: 8

enter image description here

Background: I am trying to control and acquire electrical measurement data from a Keysight 34461A digital multimeter via GBIP using Labview and CDAQ.

  • $\begingroup$ How much space do you need, and how much do you have? What is the deployment environment -- is it indoors, outdoors, AC mains available, network available, ... ? $\endgroup$ – Joe Friedrichsen Aug 21 '18 at 16:47
  • $\begingroup$ @JoeFriedrichsen, System is an indoor system, AC mains are available, but no network connection. There is no space left, I believe I need about 1-2 GB of space, $\endgroup$ – Mahendra Gunawardena Aug 21 '18 at 22:51

@Mahendra, I had run into Hard Drive Memory Space issue few months ago on my NI cDAQ. I am using cDAQ-9132 with a 16 GB hard drive, similar to your cDAQ. I was running LabVIEW Professional 2017 SP1 with all softwares installed. The memory space got full when I needed to install some additional drivers.

The cDAQ-9132 is not meant to have a full LabVIEW system running on it. The best practice is to only have LabVIEW run-time engine on the cDAQ and run LabVIEW application which is developed on a full computer with complete LabVIEW system.

To avoid memory space issue, I developed my code on the laptop which has over 200 GB memory space and has a full-fledged LabVIEW system. Once I developed the code I created a standalone application (EXE file) using instruction from the following tutorial: Distributing Applications with the LabVIEW Application Builder: Stand-Alone Applications . After that I created an installer for my application which I used to install the LabVIEW runtime engine and the drivers I needed on the cDAQ. You can find step by step instructions to create installer in the following link:Distributing Applications with the LabVIEW Application Builder: Installers (Windows).

Now to cleanup space on the cDAQ, you need to uninstall LabVIEW completely. Go to the control panel in Windows 7 and follow this tutorial: Uninstall or Repair National Instruments Software or Drivers in Windows. I have also used Temp File Cleaner which cleaned about 2 GB of space on cDAQ.

I hope it helps!

If the built-in storage is fully utilized, there are three other options for saving test data:

  1. Save to a network share
  2. Save to a USB flash drive
  3. Save to an SD card

All of these connections are on the main front panel (items 3, 15, and 10) of the cDAQ controller.

And the specifications report that the USB controller supports USB 2.0 devices and that the SD controller supports 32 GB cards.
