<P>PROBLEM TO BE SOLVED: To provide a ladder program creation device capable of efficiently creating a ladder program for a programmable logic controller from a circuit drawing for device simulation. <P>SOLUTION: A ladder program creation device comprises: a DB312 that stores model information of a simulated operation circuit drawing simulating device operation simulated by an arithmetic circuit, and ladder program information based on the model information; a simulated operation circuit drawing creation part that display on a display part the model information of a selected device as a simulated operation circuit drawing with a circuit input value definition table, a simulated operation circuit simulated by the arithmetic circuit, and a circuit output value definition table; a simulated operation circuit drawing editing part that edits each definition table in the simulated operation circuit drawing; and a simulated operation ladder program creation part that, receiving a request to create a ladder program after editing, extracts change information from the difference obtained by comparing the edited drawing information and model information registered in a database and that creates a simulated operation ladder program file reflecting the extracted change information. <P>COPYRIGHT: (C)2013,JPO&INPIT |
