Netzwerk-Kontrollsystem und darin verwendeter Kontroller und Vorrichtung

摘要

The network control system of the invention is composed of a control object device connected to the network, and a controller provided with a remote controller. In this network control system, a predetermined duration is specified for expressing the transmission duration of the message to be transmitted in the network to the operation of the remote controller. When the user manipulates the remote controller, the remote controller converts the received remote controller signal into a message including operation information showing which button has been manipulated in which manner, and transmits the information to the control object device on the basis of the duration. On the other hand, the device receives the message, and acquires the operation information on the basis of the duration, and hence operates as specified.
