<p>PROBLEM TO BE SOLVED: To provide a device supervisory control bus method making it possible to effect control between a supervisory control board and packages to be supervised, while maintaining the number of backboards or the like of the packages at a required minimum. SOLUTION: To effect control between the supervisory control board 2 in a device 1 and the plurality of packages 1 to n to be supervised which are connected to the supervisory control board 2 via buses A and B, the supervisory control board 2 creates mounting position information data in advance for each of the packages 1 to n, and delivers the data to each of the packages 1 to n. The package 3 stores the mounting position information data delivered, and the supervisory control board 2 creates supervisory control data by adding the mounting position information data to the data used for control of the package 3, and delivers the supervisory control data to the package 3. The package 3 then processes the supervisory control data only when the stored mounting position information data coincides with the mounting position information data added to the supervisory control data.</p> |
