I have I 9792 Real-time ethernet gateway, it has two ethernet ports. As one of the ethernet port is used for communication with my NI WSN Nodes and the other one is left free. So i was planning to connect the second port with cDAQ 9191 WI-FI Chassis. Is it possible to do this, IF YES then How?
You cannot do that, since real-time controller doesn't support DAQmx.
Whilst you cannot use NI DAQmx you could use the web API for the 9191
It would allowing to acquire relatively slow data and will require a lot of programming compared to the DAQmx driver but it is a way forward
