Hello
I use two NI cards : the first one is PCIe-6251 and the second one is USB NI-6221.
I would like to know if it is possible to "stop" a communication between the card and the system which is controled.
I mean : my PCie-6251 sends Pressure command to a PID regulator. It is a continuous voltage signal (analog output signal from NI PCIe-6251). I would like to know if it is possible to stop this continuous signal (using Matlab) and to send another continuous (in fact another pressure command) signal to the PID with the USB NI-6221 card using Matlab too. And so on...
In other words : Can I find a function like DAQmxWriteAnalogF64() for instance which can stop a continuous analog input signal from a NI device ?
In fact, I would like to pilot two different NI cards which are both connected to an analog PID regulator with BNC cables, using Matlab functions.
I don't have Data Acquisition Toolbox...
I can't explain here why I need to do that but I just want to know if it is possible or not.
Thanks for your help...
