摘要:
A transmitting section spontaneously transmits a command including device information relating to a field device, to a field server. An updating section receives commands including device information which is spontaneously transmitted from field devices, and updates a database on the basis of the device information. Based on the device information stored in the database, a server communicating section communicates with the field devices.
