Hi husteadam,
PXI is based on CompactPCI which is based on the PCI standard. The RST line on the PCI bus is normally only asserted at boot up. This means, the reset line is only asserted when the computer is turned on or when the reset button is pressed.
It is normally not desirable to reset the PCI bus except at boot up because all devices would need to be reconfigured, and this configuration only occurs at boot up.
For these reasons, there is no VISA function or attribute to assert the RST line on PCI, CPCI, or PXI.
