PURPOSE:To express an arbitrary digital data in an easily understandable type by easily acquiring and storing the arbitrary digital data in a device for an arbitrary period through a data acquisition storage means, a data expression setting means, etc., and using an expression method in a type corresponding to the meaning of the data. CONSTITUTION:A data acquisition storage means 11 acquiring and storing arbitrary digital data A1-An in a protective controller for a specified period, an acquisition content setting means 12 setting data as objects to be acquired, the acquisition period of the data and the intervals of the acquisition, a data expression setting means 13 setting the method of expression of the data stored by the storage means 11, and a data display means 14 displaying stored data by using the method of expression set by the means 15 are provided. The data A1-An in the device are acquired according to content set, and displayed outside the device through the data expression method in which the data A1-An are set. Consequently, the arbitrary digital data A1-An can be displayed by an easily understandable expression. |
