| 摘要: |
| 提出了利用串口设备服务器实观普通数控设备联网的有效方案。RS—232串口服务器采用MOXA NPORT EXPRESS DE—311。一种单口型服务器。DE—311可以工作于主机／驱动模式、时：等模式、Socket模式和以太网调制解调模式，其中主机／驱动程序模式最为方便。在主机／驱动程序模式下。远端的串口设备可以映射为主机的一个虚拟COM口。原来基于COM口的应用软件(像西门子的WINPCIN)，可以不作任何修改直接用于网络中的数控设备。这一解决方案，已成功用于西门子系统数控设备的数控代码传输。 |

| Abstract: |
| An effective scheme for organizing CNC (Computerized Numerical Control) equipment network using serial device server is introduced. The RS-232 serial device server adopts MOXA NPORT EXPRESS DE-311,a single-port serial device server,which may work under master-com-puter/driver mode,equity mode,Socket mode or Ethernet-Modem mode. Under the master-computer /driver mode,the remote serial device may be mapped as a virtual COM port of the master com-puter. The application software based on COM port (such as Siemens WINPCIN) may directly used without any modification for the CNC devices in the network. The scheme has successfully applied in the NC data transfer of Siemens CNC devices. |
