Can be provided to In this case, the monitoring control client 221 may display the equipment status information of the equipment connected to the other server according to the analysis result of the equipment status message of the equipment connected to the other server.

In operation 560, the server interface 240 may determine whether the message received in operation 510 is an equipment control message of a device connected to the monitoring and control device server 200.

In this case, the server interface 240 may compare the APID included in the message received in operation 510 with the APID of the equipment connected to the monitoring and control device server 200. And, if the APID included in the message received in step 510 and the APID of the equipment connected to the monitoring and control device server 200 is the same, the server interface 240 is the monitoring control device server the message received in step 510 It may be determined that the device control message of the device connected to (200). In addition, when the APID included in the message received in step 510 and the APID of the device connected to the monitoring and control device server 200 are different, the server interface 240 may determine that the message received in step 510 is the monitoring and control device. It is determined that the device control message is not the device control message of the device connected to the server 200, and searches for another server connected to the device corresponding to the message received in step 510 using the APID included in the message received in step 510. can do.

When the server interface 240 receives the equipment control message of the equipment connected to the monitoring control device server 200, the server interface 240 may perform step 570.

In addition, the server interface 240 receives the equipment status message of the equipment connected to the other server means that the user inputs the equipment status message input to the monitoring control client 221 to remotely control the equipment connected to the other server monitoring control processor ( 220 is the case that the transfer to the server interface 240. Therefore, when the server interface 240 receives the equipment status message of the equipment connected to the other server, the server interface 240 performs step 580 to convert the equipment control message of the other server to the equipment control message. Can be sent to.

In operation 570, the server interface 240 may transmit the equipment control message of the equipment connected to the surveillance control apparatus server 200 to the surveillance control processor 220. In addition, the monitoring control processor 220 may control the equipment connected to the monitoring control device server 200 according to the equipment control message of the equipment connected to the monitoring control device server 200.
