Hello, I am trying to use the data acquisition toolbox to use my USB-231 DAQ inside of my Simulink model. The DAQ shows up inside of MATLAB and I am able to read and write, but inside of Simulink I am unable to access the board from the Data acquisition toolbox's Analog Input/Output. Is there any troubleshooting I can do to get my board to show up or is there some other workaround I need to get it to work in Simulink. Thank you for any help you can give me.

The USB-231 is not a supported device. The supported devices are listed at
https://www.mathworks.com/hardware-support/measurement-computing.html
Perhaps it "works" as an unsupported device.
However,
Note: The support package does not support counter/timer subsystems, digital I/O subsystems,
triggered acquisition, specialized voltage measurements (thermocouple, etc.),
or the use of Simulink data acquisition blocks for Measurement Computing DAQ hardware.

Also are you saying that all measurement computing devices cannot use the analog input/output blocks from the data acquisition toolbox in library browser?

All Measurement Computing devices cannot use the analog input/output blocks.
I would suggest using a MATLAB Function Block in a discrete model . However, I do not know whether it would be possible to use Acceleration mode with such an arrangement.
