Abstract

To provide a network unit, a maintenance system, a computer program, and a data transmission method for a power supply device.SOLUTION: A network unit includes: a first communication unit configured to receive data from a power supply device having a power converter; a second communication unit for communicating via a specific network; a third communication unit for communicating via communication media different from the specific network; an operation unit including a changeover switch; and a control unit for controlling communication by the first to third communication units. The control unit communicates with another device by the second communication unit in accordance with a setting in the specific network according to a state of the changeover switch. When the network unit is activated in a state in which the changeover switch is in a predetermined state, the control unit establishes a communication connection with a specific communication device by the third communication unit.SELECTED DRAWING: Figure 1
