Abstract
In a network control system, a device has screen display data indicative of its operating screen, and a controller issues a screen request (101) to obtain the screen display data, etc., as screen information (111) from the device. By using the screen display data, etc., the controller displays the operating screen. When an operation is carried out to the operating screen, its operation information and identification information of the screen display data are sent to the device as operation request (241). The device executes a function corresponding to the operation request. As a result, when the screen display data in the device is changed, the device sends the changed screen display data, etc., to the controller as screen information (121).
