Error details :

Warning: This change caused queued output data to be flushed. Use queueOutputData to queue data before starting the object.

An error occurred while running the simulation and the simulation was terminated

Caused by: Hardware is reserved (possibly by an external application). Call release to unreserve the hardware or exit the external application, and retry the operation.

Component:Simulink | Category:Block error

Images for analog output and simulink models are attached.

Please note the model runs sucessfully while being connected to a single channel and data acquistion is succesfully achieved..Image for that is attached as well.

Thank you very much for your kind help in advance.

hey guy, i find that this error may caused by we set two blocks to acquire data. if we use just one block (select two analog input channel) to realize this function ,this error can be fixed .
