Using DAQmx on cRIO on Host PC

[Seau1]

Hello Guys,
I currently have a cRIO connected to a PC via. ethernet.

The modules of the cRIO are configured as Real-Time (NI-DAQmx).

Is it possible to write the channels from the host PC?

When I create a VI (DAQmx.vi) inside the cRIO Target of the LV Project I can access and set the channels without any problem.

But on the VI (CRio Switching Panel.vi) on "My Computer" I do not see any of these channels.
Either I am not able to create a task for them in NI MAX for "My System"

No. You cannot control the DAQmx tasks on the cRIO from the PC. From the project, you are configuring the cRIO application. Once that application is deployed, only it can access the DAQmx tasks.

If you really just want control from the PC, you should be using a cDAQ, not a cRIO.

Correct, but you also can send your running program on the cRIOthe desired channel as string via e.g. a shared variable.

You can use ni/grpc-device: gRPC server providing remote access to NI device driver APIs. if you want to access DAQ channels from Windows Host directly.
