<P>PROBLEM TO BE SOLVED: To provide a method of storing and displaying operation history for displaying history of operation along with operators, which achieves efficient storing of the operation history of an injection molding machine in an extended period without duplicated information. <P>SOLUTION: When the injection molding machine is operated, authentication of the operator is requested by operator authentication recording processing (3) in a controller. An authentication record of the operator is stored in a login history file (F1). The history of the operation performed by the operator is stored in an operation history file (F2) by operation history recording processing (4). When a setting is changed by the operation, set values before and after the change are also stored. In history display processing (5), history of the operation requested of display, is read from the operation history file (F2), and information of a corresponding operator is retrieved from the login history file (F1). The operation history is displayed on a display device 1 along with the operator information. <P>COPYRIGHT: (C)2012,JPO&INPIT |
