PROBLEM TO BE SOLVED: To provide an engineering tool capable of displaying a logic sheet in which a signal for input/output setting between a control unit logic and a plant simulation logic, is used.SOLUTION: The engineering tool comprises: a logic database 1 for storing a plant simulation logic for simulating a plant's operation and a control unit logic which is a logic of a control unit for controlling the plant; and an input/output setting database 2 for storing input/output setting in which a signal of input/output between the plant simulation logic and the control unit logic is set. The contents of the respective databases are displayed by a logic display function 11 and an input/output setting display function 12. Use destination extraction means 13 extracts corresponding logic sheets of the plant simulation logic and the control unit logic in which a signal of the selected input/output setting out of the listed input/output settings, is used, and causes the logic sheets to be displayed.SELECTED DRAWING: Figure 1 |
