When the user determines that it is unnecessary to apply the common logic diagram 52 to individual plant equipment, the process proceeds to step ST68.

When the user determines that the common logic diagram 52 is applied to individual plant equipment, the related equipment extraction unit 3 (related equipment extraction function) extracts the plant equipment related to the common logic diagram 52 from the plant equipment database 51. Extract (step ST63). The common logic diagram duplicating unit 2 (common logic diagram duplicating function) duplicates the common logic diagram by the number of plant devices extracted from the plant device database 51 (step ST64). The common logic diagram duplicating unit 2 (common logic diagram duplicating function) associates the duplicated common logic diagram with the information of the extracted plant device (target device name), and creates the logic diagram 53a (immediately after duplication) of each device. ) (step ST65). After completing the association of the information with the plant equipment in the duplicated common logic diagram, the user then determines whether or not to adjust the parameters for each equipment (step ST66).

If the user determines that parameter adjustment is unnecessary for each device, the flow proceeds to step ST68. If the user determines that parameter adjustment is necessary for each device, the parameter in the logic diagram for each device is changed (step ST67). In this case, the user inputs parameters (especially internal parameters) to be set from the parameter input section 4a. The parameter changing section 4 (parameter changing function) adjusts the parameters (especially internal parameters) in the logic diagram 53a (immediately after duplication) of each device according to the parameter changing command input from the parameter input section 4a. Parameters (especially internal parameters) are assumed to be upper and lower limits of temperature, for example, in alarm display.

When the parameter change in the logic diagram for each device is completed, the flow moves to step ST68. In step ST68, the logic diagram comparison unit 7 (logic diagram comparison function) compares the logic diagram data for each device. Furthermore, the logic diagram comparison unit 7 (logic diagram comparison function) displays a list of comparison results (step ST69). The common logic diagram printing unit 8 (common logic diagram printing function) associates the common logic diagram with the difference part for each device (step ST691). Further, the common logic diagram printing unit 8 (common logic diagram printing function) outputs the common logic diagram and the difference result together (step ST692). If the output is completed, the flow ends (step ST693).

The engineering tool 100 according to the sixth embodiment includes a common logic diagram printing unit that prints the comparison result created by the logic diagram comparing unit. When printing the comparison result, based on the common logic diagram drawn by the logic diagram drawing section and the comparison result prepared by the logic diagram comparison section, the specifications of the plant equipment described in the common logic diagram are printed. , Classify into specifications common to all plant equipment and specifications not common to all plant equipment. Specifications common to all plant equipment are printed as a logic diagram of common parts, and common to all plant equipment Specifications not specified are printed as a supplemental diagram of the logic diagram of the common part. By using the common logic diagram printing unit 8 (common logic diagram printing function), the logic diagrams of the same control are printed together on one sheet, so the confirmation work of the person who checks the printed logic diagram is reduced. reduced. In addition, since the difference is also printed at the same time, it is possible to prevent misreading and omission of confirming the difference.
