Controlling device, communication system and controlling method

摘要

A controlling device for controlling a plurality of controlled devices connected to a data bus for data transmission based on a predetermined communication format comprises: an inputting element for inputting text information corresponding to each of the plurality of controlled devices; a device identification information acquiring element for acquiring device identification information from the plurality of controlled devices, the acquired device identification information being unique to each of the controlled devices; a storage controlling element for storing into a memory the text information input through the inputting element, in combination with the device identification information acquired by the device identification information acquiring element; and a display controlling element which, based on the device identification information acquired by the device identification information acquiring element, retrieves the text information stored in the memory in combination with the device identification information, the display controlling element further displaying the retrieved text information. This allows a user to recognize the controlled devices more easily than if they were displayed together with their preinstalled ID information.
