Patent ID: 8321602

Claim:
A device management apparatus comprising: a device DTM that controls a field device; a communication DTM that controls a communication between the field device and the device DTM; a FDT frame application that manages the device DTM and the communication DTM; and a monitoring DTM that performs monitoring and collecting of data transmitted between the device DTM and the communication DTM and outputs the data to the FDT frame application, the monitoring DTM collecting first property information of the communication DTM and second property information of the device DTM, the monitoring DTM storing the first and second property information in a DTM profile list, and wherein the monitoring DTM comprises: a data receiver that receives the first property information of the communication DTM and the second property information of the device DTM that the FDT frame application links to the communication DTM; a data buffer that stores the first property information and the second property information that has been received by the data receiver; and a profile editor that reports the first property information of the communication DTM in the DTM profile list to the device DTM when the device DTM queries the first property information, the profile editor reporting the second property information of the device DTM in the DTM profile list to the communication DTM when the communication DTM queries the second property information, wherein the monitoring DTM is disposed between the device DTM and the communication DTM, the monitoring DTM collects the data transmitted between the device DTM and the communication DTM without effecting communication between the device DTM and the communication DTM, the monitoring DTM performs formatting of the data that has been collected by the monitoring DTM, and outputs the data, which has been formatted, to the FDT frame application.
