How to use cDAQ from PXI controller

[CoastalMaineBird]

I have a PXI 1042 chassis with PXI 8196 controller, connected to a host PC.

Currently, the PXI handles all data acquisition tasks, including collecting data from TCP connections, and local DAQ boards.

It aggregates all this data and ships it to the host in a unified manner.

Now, my client wants to add cDAQ support to the system.

I don't have a real cDAQ chassis.

I can add a simulated cDAQ chassis to the host (via MAX), and a simulated device in the chassis's slot.

But I cannot do this to the remote device.

When I right-click on the DEVICES and INTERFACES on the REMOTE systems section, I can choose CREATE NEW & SIMULATED DEVICE.

But the list does NOT include CompactDAQ Chassis.

If I do the exact same thing on the HOST, I CAN create a chassis, and populate it. Software works just as I would expect it to.

Why is this not available on the REMOTE (PXI) side?

Hello CostalMainBird,

Are you using a real time OS in your controller?

[CoastalMaineBird]

Yes, I use LVRT 8.2 and the OS is RT on the PXI box.

CoastalMaineBird,

USB DAQ is not supported on LabVIEW Real-Time.

Hello,

I have this same issue, only that I DO have a NI cDAQ-9188 Ethernet chassis.

I'm not able to see this chassis on the Network Devices of my remote system (PXI 8184, Real-Time OS).

It's not a USB chassis, so maybe it's compatible with LV Real-Time?

I don't believe your cDAQ device is compatible with the RT OS.

NI-DAQmx and NI-DAQ Driver Support: Portable Devices

Software Support for CompactRIO, CompactDAQ, Single-Board RIO, R Series, FlexRIO, and EtherCAT

The cRIO 9148 offers similar functionality for RT systems.

I see.. Thank you Tim.
