Filed: 1995-10-02
Abstract: PROBLEM TO BE SOLVED: To provide a high-reliability method with a low-performance computer by adding a processing in which respective computers detect faults and a processing in which the computer, that detects any fault, changes the destination of data transmission. SOLUTION: When a measuring instrument 4 detects the fault of a PC-Client 2, the network address of sending destination of measured data is changed from that PC-Client 2 to the address of a PC-Server 3. Therefore, the measured data rides from a LAN 5 for measurement through a router onto a system LAN and can be received at the PC-Server 3. Therefore, the PC-Server 3 can be substituted for the function of the PC-Client where the fault has generated. Besides, when the measured data are directly received from the measuring instrument 4, the PC-Server 3 transfers the received measured data to the PC- Client 2. When the PC-Client 2 returns a normal response to the PC-Server 3, a command for returning the address of data transmission destination of measuring instrument to the original PC-Client 2 is transmitted to the measuring instrument 4 after data transfer.
