xPC-Target What Is xPC Target? xPC Target is a solution for prototyping, testing, and deploying real-time systems using standard PC hardware. It is an environment that uses a target PC, separate from a host PC, for running real-time applications. xPC Target lets you add I/O blocks to your model and then use the host PC with Real-Time Workshop®, Real-Time Workshop Embedded Coder (optional), Stateflow Coder (optional), and a C/C++ compiler to create executable code. The executable code is downloaded from the host PC to the target PC running the xPC Target real-time kernel. After downloading the executable code, you can run and test your target application in real time.

xPC-Target • Hardware requirements • Software requirements — The xPC Target software requires a host PC, target PC, and, for I/O, the target PC must also have I/O boards supported by xPC Target. However, the target PC can be a desktop PC, industrial PC, PC/104, PC/104+, or CompactPCI computer. • Software requirements — The xPC Target software requires either a Microsoft Visual C/C++ compiler (Version 6.0 or 7.1) or an Open Watcom C/C++ compiler (Version 1.3). In addition, xPC Target requires MATLAB, Simulink, and Real-Time Workshop.

xPC-Target xPC Target Explorer • Configure the host PC for xPC Target • Add and configure target PCs for xPC Target, up to 64 target PCs • Create boot disks for particular target PCs • Connect the target PCs for your xPC Target system to the host PC • Download a prebuilt target application, DLM, to a target PC • Start and stop the application that has been downloaded to the target • Add scopes of type host, target, and file to the downloaded target application • Monitor signals • Add signals to xPC Target scopes and remove them • Start and stop scopes • Adjust parameter values for the signals while the target application is running

Configuring the xPC Target Host PC (1) MATLAB Command Window : xpcexpl (2) Click Compiler(s) Configuration node. (3) Enter the path (or browse) to the compiler for Compiler Path. ex) C:\Program Files\Microsoft Visual Studio (4) Click Apply to apply the changes.

xPC-Target Serial Communication Null Model Cable Wiring Before you can create and run a target application, you need to set up the connection between your host and target computers. You can use either serialor network communication. • Null modem cable — Connect the host and target computers with the null modem cable supplied by The MathWorks with the xPC Target software. You can use either the COM1 or COM2 port. • I/O boards — If you use I/O boards on the target PC, you need to install the boards correctly. Null Model Cable Wiring * the wiring for this cable for a 9-pin DB9 connector. A null modem cable that you can use to connect the host and target computers for serial communications.

xPC-Target Serial Communication (1) From the Host target communication list, select RS232. (2) From the Host port list, select either COM1 or COM2 for the connection on the host PC. xPC Target determines the COM port you use on the target PC automatically. (3) From the Baud rate list, select the baud rate for the serial connection between the host PC and this target PC. (1) (2) (3)

xPC-Target Target Boot Disk At the MATLAB Command Window : xpcexplr (2) select a target PC Configuration node. (3) From the Target boot mode list, select a boot disk mode. (4) Click the Create Bootdisk button. (5) Insert a formatted 3.5-inch floppy disk into the host PC disk drive, and then click OK. (6) When the 3.5-inch disk drive stops, remove the 3.5-inch disk. (7) Insert the boot disk into your target PC disk drive and reboot that PC.
