An information device for factory automation connected to the control device that controls an object communicates with a terminal device having a display capable of displaying a screen for remotely monitoring the control device. The screen includes one or more components. The screen data for displaying the screen includes attributes of the respective components relating to the display, and a logic executed by the programmable indicator to determine the attribute values. When the terminal device displays a screen, the programmable indicator transmits the attributes and attribute values of the respective components in the screen data to the terminal device.
Abstract: A management server controls, by use of a first database, a first audio client system that includes a first speaker and a second speaker. The first database includes a first standard characteristic impedance, which is obtained by application of statistical processing to a first characteristic impedance of the first speaker and a second characteristic impedance of the second speaker. The management server acquires a new characteristic impedance of the first speaker, compares the new first characteristic impedance with the first standard characteristic impedance, to determine a condition of the first speaker, based on a result of the comparison. The management server updates, based on the condition of the first speaker, the first standard characteristic impedance of the first database, using the new first characteristic impedance.
