NETWORK SYSTEM

摘要

Provided is a network system appropriate for remote control or remote monitoring of a facility device. When a client terminal device requests a server to execute a server side object, the server requests the facility device to execute a facility side object. A server side object execution request from the client terminal device is performed by using a first identifier attached to the server side object and a facility side object execution request from the server is performed by using a second identifier attached to the facility side object. Since the server has an identifier setting function to set the relationship between the first identifier and the second identifier, it is possible to reduce the load on the client terminal device and flexibly modify or add a facility device without considering the identifier unique to the facility device such as an IP address.
