cannot connect to real-time target.... ugh I give up!

[bpearson]

This one is really frustrating... I haven't been doing much with Labwindows for a long time, so in getting back into it... I just installed LW/CVI 2013 on a new machine in my lab.  hooked up a new PXI chassis, formatted a new drive in it and installed all the drivers.  When trying to connect to the target from labwindows environment I get the popup in the screenshot.  As you can see, the chassis is on the network, at the right ip, and the drivers are installed on the target.... what is wrong!?  Thanks.

Well i installed all the drivers from the Aug 2013 drivers disk... so not sure why the platform version would be out of date....

Hello bpearson,

What versions of CVI Real-Time Module and MAX do you have?

As a quick test, temporarily disable your firewall and try connecting again. Does that make a difference?

[bpearson]

I have MAX Version 14.0 and LabWindows/CVI Development 2013/SP1, and realtime module 2013

In a lab enviroment on an isolated subnet... no firewall on at all....

Hello,

Can you upgrade CVI Real-Time Module to 2013 SP1?

This problem occurs with CVI Real-Time Module  2013 and MAX 14.0.

great.... no... love problems like this that can only be solved by upgrading... ie spending money... I don't have maintenance anymore, so SP1 will cost me apparently... so will downgrading Max work too then?  I don't understand why MAX would interfere though if I am running Labwindows... does Labwidows environment call into Max libraries when trying to connect to a target?

Hello,

It's acutally NI System Configuration wich comes with MAX and interferes when installing CVI Real-Time on the target.

Downgrading MAX should solve the problem.

If you don't want to upgrade to CVI Real-Time Module to 2013 SP1 there is also an workaround:

    Edit C:\Program Files\National Instruments\RT Images\CVI\version\cvilvrt.cdf and do one of the following:
        Remove the CVIRealTimePeer entry.
        Specify the desired IP or host name.
    Reinstall the LabWindows/CVI Run-Time Engine for RT component to the target via NI MAX.

Have a nice day,

Constantin
