| Abstract: |
| It is proposed to adopt the network software packet"Pathworks for DOS"of DEC in the development of dual Ethernet communication function for signal acquisition and control device. The key techniques,which are applied in the development of dual Ethernet system for real time monitoring and control,are expounded,including non-blocked I / O operation of DOS application program,main-standby dual network communication of IPC,communication error-tolerance capability of dual Ethernet system based on Windows NT / 2000,prevention of repeated parameters / command downloads and so on. Its communication reliability is analyzed. |
