I have a PXIe-4135 instrument. It sometimes goes into overload protection for various reasons. It has to be reset to work again. In NI MAX, I can simply click "Reset" and it works. But I don't know how to do it in LabVIEW.

The Reset functionality in the NI MAX uses the System Configuration API. You can find an example of resetting devices using SysCfg API at <LabVIEW>\examples\nisyscfg\Reset All Devices.vi.
You can specify an expert of "daqmx" to the filter to get all NI-DCPower devices, or you can filter out the specific device by the Alias Name/ProdName.
