Abstract: The program generation apparatus includes a terminal detection unit for detecting position information including a position of a first terminal of an input/output apparatus to which an electrical wiring is connected. A display control unit displays, on a display part, a control program and position information of the first terminal detected by the terminal detection unit. The operation detection unit detects a symbol indicating the device specified by the operator. The setting unit allocates the position of the first terminal which is included in the position information of the first terminal to the symbol which is indicative of the device which has been detected by the operation detection unit.

Abstract: A plurality of modules are included by an electronic device, so as to be disposed adjacent to each other. Each of the modules includes a light emitting element configured to emit communication light toward an adjacent module disposed in one adjacent direction, and a light receiving element configured to receive communication light emitted by an adjacent module disposed in the other adjacent direction. Each of the modules disposed adjacent to each other is capable of emitting the communication light to the light receiving element of the adjacent module disposed in the one adjacent direction, and capable of receiving the communication light emitted by the light emitting element of the adjacent module disposed in the other adjacent direction.

Abstract: A machine control device includes a command unit that outputs individual operation commands to respective manufacturing machines; a power excess/shortage decision unit that decides whether time-series data on total power consumption of the manufacturing machines associated with the operation commands has maximum peak power larger than a power supply capacity of the power facility; and an operation command adjustment unit that adjusts the operation commands to the manufacturing machines from the command unit so as to adjust the maximum peak power to the power supply capacity of the power facility or less and maximize a production amount of the manufacturing machines.
