Abstract
A data communication system performs transmission and reception of data by token passing and updates data by an arithmetic process of data transmitted to and received from a slave station. The data communication system includes a management master station that updates data of slave stations, and a local station that updates data of slave stations. The management master station performs a data update when a token frame destined to the management master station is received, and the local station determines a destination of token frames transmitted from the slave stations, and performs a data update when a destination is the management master station.
