<p>PURPOSE: To provide a logic diagram preparing device which can prepare a specification description logic diagram necessary for preparation of plant operation automation program just by performing a simple input operation and while making a user understand the preparation process of the logic diagram. CONSTITUTION: The logic diagram preparing device is provided with a data input means 1 which inputs various data based on a plant operation plan, an analysis/conversion means 2 which prepares a hierarchical schedule table, i.e., the knowledge that is used for editing the input data into a prescribed data format and then preparing the timing conditions of a logic diagram, hierarchical schedule table display means 4 and 5 which selectively display the prepared hierarchical schedule table, the timing condition generation means 6 and 7 which prepare the timing conditions of the logic diagram based on the data on the hierarchical schedule table prepared by the means 2, an IBD generation means 10 which prepares a logic diagram based on the generated timing conditions, and the logic diagram display means 4 and 12 which display the prepared logic diagram.</p> |
