<p>PURPOSE:To avoid the misoperation of make-and-break control of power apparatuses securely and easily by a method wherein interlocking conditions of the respective power apparatuses are provided as table data and operation instructions are given by referring to the table of the interlocking conditions. CONSTITUTION:The operation of power apparatuses is performed by referring to an interlocking condition table. For instance, as shown in the attached table, the data items and contents of the respective apparatuses are written in the table beforehand to set the interlocking conditions. Then, by referring to the interlocking condition table, it is judged whether the operation of the object apparatus satisfies the interlocking conditions or not. If the conditions are not satisfied re-selection of operation conditions is instructed and the operation contents and the operation conditions are selected again. In other words, if the operation instructions are not proper, the apparatus is interlocked. If the interlocking conditions are satisfied, the operation start is permitted.</p> |
