xPC Target

Using GPIB Drivers

xPC Target uses a combination of Simulink blocks and MATLAB structures to support GPIB communication from your target application and target PC. The topics in this section are

• Adding GPIB Driver Blocks -- Add the setup and send/receive blocks you need to add to your Simulink model for GPIB communication.
• Creating GPIB Message Structures -- Create the initialize, send/receive, and termination message structures you need in the MATLAB workspace.

This section uses an example of a multimeter attached to a GPIB bus with an address of 16. This multimeter needs the initialization command

• :conf:volt:dc 
  

to set the device to read DC voltages, and needs the command

• :read? 
  

during each sample interval to read one voltage value
