Abstract

PURPOSE:To prevent the careless change of controlling set data by inputting a password by each operator at a function selection time and fixing a set available range of control data according to the work level registered by the operator. CONSTITUTION:In the set data protection method for preventing malfunction in a process controlling computer which uses set data c of memory b dependently upon CPU a to control process e through I/O device d, when set data c of memory b is changed, password k for each operator and operation level permitted for the operator are previously registered to collate the passward, which is inputted by the operator at a change operation time, with registered password k; and when the inputted password is one of registered passwords k, operation level 1 permitted for the operator is calculated. Then, the caluculated operation level is compared with set function level m selected by the operator, and operation is permitted in case of 1>=m.
