FIG. 5 is a diagram illustrating a fourth specific configuration example of the system illustrated in FIG. 1. Referring to FIG. 5, a system 10d includes elements 100 of which some also function as a manager 200, a tablet functioning as a UI device 400, and a server 300.
Unlike the foregoing first to third examples, at least one of the elements 100 functions as the manager 200 in the system 10d. In the system 10d, the elements 100 mutually form a mesh network through Bluetooth (registered trademark). In such a configuration, even when communication with the server 300 and the UI device 400 (tablet) is temporarily disconnected in the system 10d, the elements 100 can autonomously perform a linkage operation.
Fifth Example
FIG. 6 is a diagram illustrating a fifth specific configuration example of the system illustrated in FIG. 1. Referring to FIG. 6, a system 10e includes elements 100 of which some function as a manager 200, a tablet functioning as a UI device 400, and a server 300. The system 10e is an example in which the manager 200 is incorporated into any of the elements 100 in the system 10c in the foregoing third example.
