摘　　要：Math Works公司提供了基于RTW的x PC Target开发环境。使用x PC Target时,用户可以将1台PC机转变为一个实时系统,以实现对外部I/O设备的实时控制;x PC Target为外部I/O设备时,提供了部分驱动,同时,支持其它I/O设备的连接,此时,也需要用户编写驱动模块来实现对设备的接入。文章以Moxa CP118-U-I为例,介绍了使用S-Function编写x PC Target下可调用的串口驱动模块的方法,并进行了实时仿真试验验证,实现了控制器与仿真机的实时串口通讯,具有较高的工程应用价值。The user can change one PC as a real-time system,to realize the real-time control of external I/O devices;xPC Target for external I/O devices, provides part of the drive, at the same time, connection, support other I/O devices at the same time, also need to access the user written on equipment drive module.This paper takes Moxa CP118-U-I as an example, introduces the use of S-Function prepared xPC Target can call the serial driver module, and the real-time simulation,real-time serial communication controller and simulation machine,has high engineering application value.
