Data Acquisition Toolbox doesn't work with Simulink

Hello,
I am using the NI 9188 Chassis with different Modules for IO purpose. It works properly with Matlab and the Data Acquisition Toolbox, that means things like
myDAQ = daq.createSession('ni');
myDAQ.addAnalogInputChannel('cDAQ9188-AI' , 'ai0' , 'Voltage');
myDAQ.DurationInSeconds = measurement_time;
myDAQ.Rate = measurement_rate;
myDAQ.startForeground();
are working fine. But when I try the In- and Output Blocks within Simulink, the Blocks only say: Device: none, and I'm not able to configure anything.
I am using Windows XP with NIDAQmx Driver and Matlab 2012a. Things like daq.getVencors oder daq.getDevices are showing up the correct hardware.
What I found out is, that my Hardware is only able to deal with the session base interface. Isn't it supportet with Simulink?
Thanks for any efforts in advance.

If you use Real-Time Windows Target Blockset, check if your hardware is in the list of supported hardware.

If you use xPC Target Blockset, check if your hardware is in the list of supported hardware.

Yes, Data Acquisition Toolbox provides blocks that are only available using the Legacy interface and the 32-bit version of MATLAB.

My hardware seems unfortunately not to be supported by them. I've tried another blockset, called daqlib, wich I thought is supposed to work with any of the here listed hardware:

My Chassis is the NI9188 and the Modules are NI9205 and NI9402.
Do you have any further ideas? Thanks for your help so far.

The Data Acquisition Toolbox appears to me as a Blockset. It's displayed in the same level as the others are.
S-Function could be a solution for e.g. outputting single values to an analog output, but what if I need a whole Signal, for example a Sine with a special duration?
Thanks so far.

I have tried the following: Create an s-function for analog input.
In the initialisation function i create the session. in the output fuction I call the inputSIngleScan().
Is this a proper way to do this?
THanks for helping
