PROBLEM TO BE SOLVED: To present in an understandable manner a part where conditions for driving a coil are written.SOLUTION: A processing part executes unit searching processing, which searches a ladder diagram for a circuit block having a coil closing or opening a contact point contained in a search target block designated by a user. Further, the processing part carries out the unit searching processing repeatedly which is targeted to the circuit block searched for by the unit searching processing. Moreover, the processing part displays, in a search result display screen 102, the circuit block searched for by each unit searching processing as a circuit block one-level lower than the circuit block as the search target. |
