It is my understanding that you want to generate a signal in Simulink and output it using an NI PCIe-6341 data acquisition (DAQ) device.
To achieve this, you need to use the Data Acquisition Toolbox from MathWorks and the appropriate “NI-DAQmx Support Package” in Simulink. Here's how you can do it:
  • Use signal generator blocks (like Sine Wave, Step, or Signal Builder) in Simulink to create your desired waveform.
  • Install the NI-DAQmx driver and the NI DAQ Support Package for Simulink (available from the Add-On Explorer).
  • In your Simulink model, add the block: Analog Output (Simulink Support Package for NI DAQ Devices).
  • Configure the block by selecting NI PCIe-6341 and choose the analog output channel.
  • Set the sample rate, signal amplitude, and timing to match your hardware requirements.
For further reference on how to send signals from Simulink to an NI device, you may visit the following link:
For more information on supported hardware and integration with NI DAQ in Simulink, refer to this documentation from MathWorks linked below:
Hope this helps!
