PROBLEM TO BE SOLVED: To solve the problem that since a huge number of protocols and APIs(Application Programming Interface) are generated every day as the result of consideration of a large number of equipment and software, the learning costs and operation costs of users and API providers or the like are increased beyond a controllable range in an integrated operational system.SOLUTION: An API providing server is connected via a network to an API client who requests an API, an HMI(Human Machine Interface) to be operated by an infrastructure operator and a plurality of communication nodes, and configured to preliminarily register event information due to a change in the state of each communication node and a settable function as an API, and to dynamically change the availability/unavailability of the API on the basis of the number of times of event notification which has occurred in each communication node and the preliminarily defined value or range of a threshold for the number of times of notification, and to, when the API is available, provide the preliminarily defined API to the API client. |
