<p>A sequence control method applicable to sequence control for performing a specified work by moving a plurality of execution units (108). When a time chart is derived from an operation chart, an I/O unit on a time chart is derived by a rule corresponding to the type of an I/O unit on an operation chart and the state vector thereof is generated. When a relation vector is derived, a relation vector has one to one correspondence between the time point and the output term and the attribute thereof is [ON, or OFF/no variation] logic. In case of a relation matrix, sets of corresponding time point No, corresponding output term, attribute and positive/negative term vector are arranged in the order of time point No. At the time of calculating the output state, the time point is managed and a calculation is made only for [current], response: a=m•x output: y=f(a,z), where z: attribute [ON, or OFF/no variation] logic. A computer (100) can be used in various fields of application while reducing the execution time.</p> |
