PXIe-8840 trouble shoot

[aqib355]

I had worked on a PXIe system previously and I switched to a new system and there are some differences in the MAX software that I cannot figure out.

Old System: PXIe-1078 chassis with an interface card (PXIe-8381). It was plugged into the computer with Windows OS on it and operated it using MAX software.

New System: PXIe-1078 chassis with embedded controller (PXIe-8840 Quad-Core) plugged into the computer with Windows OS and operated using MAX software.

On the old system with only the interface card, I was able to see all the cards in the Devices and Interfaces menu (see Old_1) but in the new system with the embedded controller, I cannot see the cards (see New_1).

Also, when I wanted to make a new channel on the old system, I could see which card to select (see Old_2) but in the new system, I cannot see the cards (see New_2).

Is this what I am supposed to be seeing?

I am trying to connect some sensors and I am confident that the wiring and the hardware are connected right. I was able to use these sensors in a similar config with the old system but I am unable to do that with the embedded controller. After spending a lot of time with this, I am not even getting a signal. The output windows opens up and there is no input from any sensor. Maybe I cannot figure out how to properly use the embedded controller. Any idea what might cause this?

Any help is deeply appreciated! Thank you!

Are you trying to access the PXI cards from your normal Windows computer?

Your PXIe-8840 is a computer in itself with its own operating system. This can be either Windows in which case you would have to run your NI-Max software on this system to see the individual PXI cards or it can be NI Linux RT, in which case you will need to use LabVIEW Real-time in order to access it from your Windows computer as Real-time remote device.

If your PXIe-8840 runs Windows, the experience is very similar to what you had before but you need to work on the PXIe-8840 system with LabVIEW, and connect a monitor and keyboard to it.

If it runs NI Linux RT you are in for a considerable change in your development experience as you are now programming in LabVIEW Real-time.
