In a distributed type plant monitoring/controlling apparatus, data required to be synchronized with each other in a system can be synchronized with each other, and a system with high reliability and a high performance is provided. In a plant monitoring/controlling apparatus in which a plurality of clients communicated with each other via a network are arranged, the plant monitoring/controlling apparatus is equipped with one client functioning as an original client with respect to each of functions, the original client corresponding to a software server for each of the functions used to monitor and control the plant; an original client of a first function transmits data related to the first function to another client; and the another client receives the data transmitted from the first function original client to store the received data into a storage unit provided with the another client, whereby the data stored in each of other clients are synchronized.
