PURPOSE:To secure the concurrence of data among software modules through simple constitution by automatically allowing the execution of the software modules in the order depending upon a flow of data. CONSTITUTION:Software modules for realizing functions of a regulator and an arithmetic device are used in combination to perform control, and the execution of the software modules is allowed automatically in the order depending upon a flow of data. For example, when the ratio of fuel F and air A to be supplied to a furnace is controlled by the modules 1-19, the execution of modules which are not in referencing operation is carried out according to their numbers. Namely, althrough the execution is performed in the order of modules 1, 2, and 3 firstly, a module 4 refers to data of another module 7, so a module 13 which succeeds to #4 among modules relating to the module 7 and is not refers to other module data is selected to perform the execution in the order of modules 13, 12, 7, 4, 8, and 5. |
