PURPOSE:To prevent the production of input mistake, by checking if the program corresponds to the conditions of ''unnecessary data'' preset, when it is input. CONSTITUTION:The conditions of ''unnecessary data'' are written in a register R2. The ''unnecessary data'' are the conditions which are not taken place actually such as different ones operated in the same time and no repetition of the same operation within + or -10min from a certain time. The program input from an input device E is once stored in a register R1 and the discrimination is made with the program data M stored already under the condition of ''unnecessary data''. As a result, whether the program newly input is unnecessary corresponding to the program data already stored or not, is judged. Especially, it is effective to the addition of data and correction mistake. |
