Missing Real TIme Plug In

[jeepers52004]

Where does DAQmx fit into the installation order?

I have no issue opening and accessing the daq device using LabView 2014.  When working in a project in LabView 2013, I don't have an option to add a cDAQ.  I've made sure I have daqmx installed and this would have been installed from initially receiving the cdaq.  It was at version 14.something which probably installed with LabView 2014.  I uninstalled the 14 version and reinstalled daqmx 9.8 with no change to the issue.

I'm working through uninstalling all of the LabView 2014 software now and appreciate any other suggestions to try before uninstalling LabView 2013 and completely starting over.

Thanks.

Hi Michael,

What hardware are you using? The cRIO is a real-time based system that does not support programming with DAQmx due to the I/O on the FPGA. Are you using a CompactDAQ Controller such as the ones described in this whitepaper?

http://www.ni.com/white-paper/14029/en/

If this is the case, you will need to install the following software on your host computer in this order:

LabVIEW

LabVIEW Real-Time

NI-DAQmx

These components will need to be installed separately. More information on the described on page 1-9 of the following document:

Hello,

I have both a cRIO and a cDAQ.  I've not done much outside of using VeriStand on the cRIO and have written a couple applications for the cDAQ.

The cDAQ is the hardware I'm having issues with at the moment.  After uninstalling everything related to LabView 2014 and reinstalling daqmx 9.8, I can at least add the cDAQ as a device in a project and open the VIs I had previously created. 

What I'm seeing in MAX is that all the tasks I had created for this project have red x's over them and I can't modify the tasks without getting an error nor can I add new tasks.

To set my development laptop (and hopefully a backup laptop) back up to work with both the cRIO and the cDAQ, would I install:

LabView Development System

Real Time Module

FPGA Module

Daqmx

RIO Drivers

I had everything set up and working just fine.  I was able to try things out on the cRIO and write and deploy applications to the cDAQ.  This all changed when I wanted to install LabView 2014 to see how useful the new features might be to what we are doing. 

As a question, even though a new instance of LabView was installed (2014), certain components were updated that caused incompatibilities with the 2013 version?

Thanks for all your help!

Were you able to install all of those software components after installing LabVIEW 2014? What specific components/functionality are you referring to that are missing/incompatible? Are you able to delete the tasks in NI MAX?

I have uninstalled LabView 2013 and 2014 and reinstalled LabView 2013 sp1 along with the real time and fpga modules.  I've also installed daqmx 9.8.

The tasks in MAX no longer have the red x's over them and I can add channels, however, the tasks still have error 88700 - internal error - when trying to save the tasks. 

In the actual VI under the target in a project, I can edit the tasks and get the same internal error when I try to add TDMS logging to the task.  If I uncheck logging, I do not get the error.

I don't know if or how this factors in but this applicaiton I'm trying to edit is running deployed on the cDAQ and recording data just fine.

Thanks

Hi,

I would like to clarify a few things from your last post:

1. You are able to successfully run your program and record data despite these errors?

2. Do these errors show up in the same place every time? (either when you edit the task, or when you add TDMS logging)

3. What are the task settings?

4. Have you tried running any shipping examples to see if the same error occurs?

I would first recommend upgrading DAQmx 14.2 to see if that resolves the issue.
