Abstract
A system and method of identifying faulted devices in an Ethernet network of a building management system (BMS). The system includes a network manager device, a first client device, and a second client device. A first port of the first client device is connected to a first port of the network manager device, a first port of the second client device is connected to a second port of the first client device and a second port of the second client device is connected to a second port of the network manager device. The network manager device is configured to transmit a frame having a count field. The first client device is configured to increment the count field once based on a successful transmission of the frame to the second client device and increment the count field twice based on a failed transmission to the second client device.
