No device names appear when initializing a session with NI-DCPower on NI Linux Real-Time Targets

When selecting a resource name with niDCPower Initialize With Channels.vi in LabVIEW with a LabVIEW version prior to 21.0 on an NI Linux Real-Time target, the drop-down menu for selecting resources appears empty and you cannot select a device that is in your system.


Workaround:

  1. Manually enter the resource name for the device you want to use. Use NI Measurement and Automation Explorer (NI MAX) or NI System Configuration software to retrieve the resource name for any devices in the system. Or
  2. Use LabVIEW version 21.0 or later.

Test Panels in NI MAX do not work for NI-DCPower devices on Real-Time Targets

For NI-DCPower devices on a NI Linux Real-Time or PharLap target system, the Test Panel button in NI Measurement and Automation Explorer (NI MAX) opens Instrument Studio instead of a test panel.

Workaround:

Use an example VI or a similar VI and deploy it to the target to exercise functionality instead of a test panel.
