The study of network communication between the master controller and external equipments is done in the paper. This system uses C/S (Client/Server) mode which is economy and strong. Moreover it has the advantage of extensibility. By adding more clients and servers can provide the performance of the system when the task increases. The operating system based on network communication programming between Windows NT two machines is presented in this paper. The working process, programming steps, technical characteristics etc. based on C/S mode are also proposed in detail.
