Beschreibung
Zusammenfassung:	A program development support unit includes an arithmetic unit and a storage unit. A ladder diagram editing program and an edited ladder diagram program are stored in the storage unit. The arithmetic unit is configured to execute the ladder diagram editing program to edit the ladder diagram program, and store the ladder diagram program in the storage unit. The arithmetic unit is configured to allocate two-dimensional coordinates to a ladder diagram expressed by the ladder diagram program. The arithmetic unit is configured to detect two-dimensional coordinates and types of circuit elements included in the ladder diagram, and detect two-dimensional coordinates of any vertical connection lines included in the ladder diagram. The arithmetic unit is configured to store the circuit elements, the vertical connection lines, the two-dimensional coordinates of the circuit elements, and the two-dimensional coordinates of the vertical connection lines in the storage unit in association with each other.
