I/O Driver Blocks

I/O Driver Blocks
You add I/O driver blocks to your Simulink model to connect your model to
physical I/O boards. These I/O boards then connect to the sensors and actuators
in the physical system.
This section includes the following topics:
•“xPC Target I/O Driver Blocks”
•“Adding I/O Blocks with the xPC Target Library”
•“Adding I/O Blocks with the Simulink Library Browser”
•“Defining I/O Block Parameters”
xPC Target I/O Driver Blocks
A driver block does not represent an entire board, but an I/O section supported
by a board. Therefore, the xPC Target library may have more then one block
for each physical board. I/O driver blocks are written as C-code S-functions
(noninlined S-functions). We include the source code for the C-code S-functions
with xPC Target.
xPC Target supports PCI and ISA busses. If the bus type is not indicated in the
driver block number, you can determine the bus type of a driver block by
checking the blocks parameter dialog box. The last parameter is either a PCI
slot for PCI boards, or a Base Address for ISA boards.
