PURPOSE:To operate a monitor device excellently, by parallel operation of different new and old data constitution, while keeping the continuity of monitoring and recording even with the data constitution different between two systems, in a monitor device consisting of a dual system. CONSTITUTION:A computer 1 discriminates if maintenance key words 31 and 41 of auxiliary storage devices 3 and 4 are equal, after setting input and output signals. If they are equal, data take-over is made from the device 4 to the device 3 as to all data files 32 and 42 and the computer 1 and a computer 2 operate with shared processing. On the other hand, if the key words are not equal, the data take-over is made from the device 4 to the device 3 as to the file 32 corresponding to a dual write flag 33 except a file data 35 of the device 3. Whether the parallel operation or a single operation is discriminated by a digital input. When the single operation, the computer 2 is stopped and the computer 1 performs all the processings and in case of the parallel operation, the computers 1 and 2 share all the processings. |
