Did you try to change the device address through NI FUBS Configurator? The detailed information please refer to the NI-FBUS Configurator User Manual. Also, NI provides an example to set the device address through the VI API. You can find the example "NI-FBUS Set Tag And Address " in the " ...\National Instruments\LabVIEW 2017\examples\NI-FBUS\Interface Device".
Please let me know if you have any questions, and I shall be happy to answer them.
I am so delight to see someone discussing the issue of modifying device tags.
Do you know how to modify device tag through NI-FBUS 16.0 .NET Framework packs? (Device's tag property is read only)
After read NI-FBUS VI Help, i found it is easy to modify device tag through LabView. But as a .NET developer i'm still wondering if there is a way for .NET to make it.
I'm looking forward to your reply.
