Unable to find target's IP programatically on a "Non-development" system

[XM43]

Hi,

Hope you are doing well,

I was hoping if some can guide in the right direction for problem mentioned below:

Problem Statement /Case:

I have a VI (attached and included block diagram screenshot) which finds target's IP address as a part of starting sequence and then updates it in a global variable in another sequence. Which is later used in multiple parts of the main application. Ideally, there would just one method instead of 3 as shown.

• Screenshot for quick look

Entire application works as expected on Development system. But not on a non-development system, VI (exe) Identify device name and alias but returns 0.0.0.0 as IP.

Hardware: sbRIO-9638

LabView Version: 2019 Professional Full

I would really appreciate if anyone has any suggestions or recommendations.

Additional Information:

Troubleshooting so far on Non-development system:

-I ran the application on debug mode and found that the application is able to identify the device name and the device alias but it returns 0.0.0.0 as IP address.

-Just using string to IP function in multiple mode returns "Preferred IP" addresses as can be seen in "cmd" window.  (e.g. 172.22.11.1 (preferred) instead of 172.22.11.2 (assigned)).

- I can see the device in NI MAX and the IP address as well.

Software Installed on Non-Development PC:

- While building the application, under the additional installers section, following software and drivers were selected: (Since I was not sure what could be causing it, I included a bunch for no reason)

• Microsoft Silverlight 5.1
• NI Compact RIO Runtime 19.5
• NI Common Runtime 19.0 for .NET
• NI RIO Compact Software Configuration support
• NI LabView Runtime 2019
• NI MAX (and NI measurement studio common runtime 19.1)
• NI PXI platform Services runtime 19.5
• NI System Configuration (.NET and Runtime)
• NI System Web Server 2019
• NI Variable Engine
• NI Web-Based Configuration and Monitoring 19
• NI-RIO Software Configuration Support 19.0
• NI-Visa Runtime 19.5

-Could not include the installer due to size restrictions.

I don't have RIOs so I don't know if this will work, but could you just use the property for the IP address directly instead?

Hi Kyle,

Thank you for your response. I will implement it and let you know how it goes.

Hi Kyle, previous reply was by a mistake.

Firstly, I did try out your suggestion but unfortunately it did not work and is giving out an error -2147220623 (Property node does not exist for this resource) or may be I did something wrong. So I attached a screenshot and also the VI if you wouldn't mind taking a look.

Secondly, I explored more ways to find IP address and came across "Find Systems.vi" and it does work on both the development and non-development system as expected.

Third, even though I have something that works now, I am curious to know as to what was wrong with my first approach? If you or anyone else has an explanation I would really appreciate it.

I think Find Hardware works for systems you already added to your system, while Find Systems also searches the network for devices nod added to your system.

I have a new sbRIO-9638 card that I am unable to get in contact with. It never turns up in Max. Do you think your program would find it then ?
