  • Patent number: 11277279
    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. A third port of the first client device is connected to a port of a device external to a ring of the network. The network manager device is configured to transmit a frame having a count field.

  • Patent number: 11274844
    Abstract: Systems and methods are provided for monitoring and controlling one or more environmental conditions of a building. The method comprises obtaining feedback from a first sensor at a first location within the building and feedback from a second sensor at a second location within the building. The method further comprises combining the feedback from the first sensor with the feedback from the second sensor in a weighted manner to generate a combined feedback, wherein a weight of the feedback from the first sensor relative to a weight of the feedback from the second sensor is based on a time of day. The method finally comprises operating HVAC equipment to drive the combined feedback toward a setpoint for the building.

  • Patent number: 10985986
    Abstract: A network system for interconnecting an operational technology (OT) network and an information technology (IT) network in a building. The network system includes an OT network, an IT network, and a network tool. The network tool is configured to obtain a current network configuration of a plurality of OT network switches in an OT network. The current network configuration includes at least one of the network addresses of the plurality of OT network switches and a routing table associated with the plurality of OT network switches. The network tool is further configured to update the routing table to route network traffic between the OT network and an IT network. The network tool is further configured to update the network addresses of the plurality of OT network switches to have network addresses within at least one subnet of the IT network.

  • Publication number: 20200076694
    Abstract: Systems and methods for automatically configuring an Internet Protocol (IP) network are provided. The system can receive inputs including information specific to a building automation system (BAS) and information specific to the IP network. The system can identify network controllers and BAS devices supervised by the network controllers. The system can allocate BAS devices supervised by the network controllers to subnets and access switches. The system can consolidate two or more subnets under the same switch when determining that the two or more subnets can be consolidated under the same switch. The system can perform IP planning for the IP network and can generate a tailored configuration file for each access switch and aggregation switch in the IP network.
