2D arrays are not supported using the RT-FIFO VIs. But it is possible to change data into a 1D array and pass that data using these VIs. First the 2D data needs to be concatenated into a 1D array, then you will send it to the RT-FIFO write like normal. After you read the data from the RT-FIFO read you will need to use the Reshape Array VI to turn the 1D array back into the original 2D data.
