MCC USB-231 compatibility with Simulink

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.

So there is no way to incorporate my daq into a simulink model at all? I know you are able to feed data from the matlab workspace into simulink and vice versa.

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

[Walter Roberson]

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.
