In a system having a control server and a control device that connects to the control server through a global network, the control device can appropriately handle processing when normal communication with the control server is not possible.

When normal communication is not possible with the control server, the client-function unitcommunicates with the server-function unitas a client of the server-function unitbased on the stored access code, and executes processes with the server-function unit
