Abstract
A BACnet MS/TP communication network analysis system includes: a monitoring node for performing a first filtering on a frame received from the network, configuring a monitoring frame by adding a monitoring frame header to the received frame, and transmitting a frame corresponding to a message created in the BACnet visual test shell (VTS) to the communication network; and a monitoring module for receiving the monitoring frame, performing a second filtering thereon, outputting a result of the second filtering, transmitting a part of the monitoring frame on which the second filtering is performed to the VTS, receiving a message from the VTS, determining a destination address of the network to which the received message is transferred, configuring an MS/TP frame on the basis of the received message and the destination address, and transmitting the configured MS/TP frame to the monitoring node.
