A terminal device which communicates with an information device for factory automation to be connected to a control device which controls an object, the terminal device comprising:

• a display capable of displaying a screen for remotely monitoring the control device;
• and
• a control unit of the terminal device for controlling the terminal device,
• wherein the screen includes one or more components placed on the screen,
• the screen data for displaying the screen includes attributes of the respective components relating to display, and a logic executed by the information device to determine attribute values which are values of the attributes, and
• in a case of switching the screen of the display, the control unit receives the attributes and the attribute values of the respective components placed on the screen in the screen data from the information device.

A non-transitory computer-readable recording medium that stores a program for causing a computer to execute a control method of controlling an information device for factory automation to be connected to a control device which controls an object, the control method comprising:

• communicating with a terminal device having a display capable of displaying a screen for remotely monitoring the control device;
• and
• controlling the information device,
• wherein the screen includes one or more components placed on the screen,
• screen data for displaying the screen includes attributes of the respective components relating to display, and a logic executed by the control unit included in the information device to determine attribute values which are values of the attributes, and
• in a case where the terminal device switches the screen of the display, controlling the information device comprises transmitting the attributes and the attribute values of the respective components placed on the screen in the screen data to the terminal device in the communication.
