xPC Target

Input/Output Driver Support

xPC Target supports a wide range of I/O boards. The list of supported I/O boards includes ISA, PCI, PC/104, and CompactPCI hardware. The drivers are represented by Simulink blocks. Your interaction with the drivers is through these Simulink blocks and the parameter dialog boxes.

I/O board library - The I/O driver library contains Simulink blocks for xPC Target. You drag-and-drop a block from the I/O library and connect I/O drivers to your model the same way as you would connect any standard Simulink block.

Input/Output support - The I/O device library supports over 40 standard boards. Input/Output boards plug into the target PC expansion bus, or are modules in PC104 and industrial PC computers. xPC Target supports the following I/O functions:

• Analog input (A/D) and analog output (D/A) - Interface sensors and actuators to your target application
• Digital input and output - Interface to switches, on/off devices, and communicate information in parallel
• RS232 support - COM1 or COM2 ports for serial communication
• CAN support - CAN-AC2, CAN-AC2-PCI, and CAN-AC2-104 boards from Softing GmbH

The xPC Target CAN drivers enable you to interface with a CAN fieldbus network to provide communication through a CAN network between real-time applications and remote sensors and actuators. The xPC Target CAN drivers are compatible with CAN specification 2.0A and 2.0B and use the dynamic object mode.

• GPIB support - Special RS232 drivers support communication with a GPIB control module from National Instruments
• Counter - Pulse and frequency code modulation applications
• Watchdog - Monitor an interrupt or memory location, and reset the computer if an application does not respond
• Incremental encoder - Change motion into numerical information for determining position, direction of rotation, and velocity
• Shared memory. Use with multiprocessing applications
