Abstract

A data collecting device collects operation data of facility equipment that constitute a facility device control system. Upon receiving a collection data request command from a monitoring device, the data collecting device reads one or multiple items of operation data of the type specified by the collection data request command from among multiple items of collected operation data, and sends to the monitoring device response data wherein the read data is stored in a prescribed format. When a user inputs an operation that requests monitoring of operation data, the monitoring device has the user select a desired operation data type from among the operation data types that can be disclosed to the user, and sends to the data collecting device a collection data request command wherein the selected operation data type is specified. Upon receiving the response data from the data collecting device, the monitoring device displays, in the prescribed format, one or multiple items of operation data included in the response data.
