Abstract
Recently, together with development of communications technology, monitoring and control systems have been used in many fields. When monitoring and control systems are developed, one of important things is considered about a redundancy so that the system can be operated normally whenever hardware faults are occurred partly.


In this paper, we introduce a monitoring and control system with a redundancy function for servers and networks. The system, therefore, has an active server and standby server. Each server also has 3 communication ports, and 2 ports are connected to all field units and 1 port is connected to another server. In fields, all field units have to be constructed 2 communication ports connected each server through communication lines. Also, each server's communication program is implemented by analyzing and handling fault elements, and is modularized for linking easily with a monitoring and control module. An experiment with 2 servers and 2 field units is constructed to demonstrate its effectiveness.
