cRIO-9024 Gateway Address - How to change this programmatically without rebooting?

[Chris_12345]

I would like my cRIO-9024 (LabVIEW 2014) application to be able to change the gateway address of the controller and then implement the change without having to reboot the controller.

Currently, the only method I can see to programmatically change the gateway address is to edit the ni-rt.ini file, and then reboot the controller. I would like to avoid having to reboot the controller. Is there a way to programmatically stop and start the ethernet service, or something equivalent?

NOTE: I have not tried this and it may not work.

Using the Software Management sub palette under System Configuration of RT Utilities you can set the IP Address (sub-net, discovery type, etc...)  Again, I haven't tried it and have no 9024 handy to test it on.

The 902x cRIOs run VxWorks, you have to reboot it to change the IP. I expect the same is true for the gateway IP and DNS configuration.

I will note that the newer LinuxRT cRIOs can do this 🙂 (906x and 903x series).

Sorry for the delay in responding. I finally tried this out, and using the SysCfg utilities works. I use Initialize Session, then set the Gateway Property, then Save Changes, then Close. A re-boot is needed for the change to be applied.
