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