The present invention improves the convenience of the design of a system by making it easier to verify power consumption when designing and building an FA system or the like. An operation screen (90) is displayed, for example, upon execution on a PC or the like of software for supporting the design of a control system. It is possible to design the configuration of a control system in an editing region (91), and a plurality of unit images (82) representing an IO unit are connected in order to a unit image (81) representing a communication coupler. It is also possible to insert a power-source-supply unit into this configuration. An icon (72) indicates an insufficient supply of power to the units downstream of the unit indicated by a selected image (83). When a user mouses the pointer (71) over the icon (72), the detailed contents of the icon (72) are displayed in a message (73). The designer or the like is capable of easily verifying the position at which a power-source-supply unit should be added. |
