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.
