Abstract: A building management system that includes a plurality of slave devices, a remote server comprising a slave device configuration database, and a master controller. The master controller is configured to receive slave device configuration information stored in the slave device configuration database. The slave device configuration information includes at least one of cooling tower configuration parameters, chilled water pump configuration parameters, condenser water pump configuration parameters, air handling unit configuration parameters, rooftop air handling unit configuration parameters, variable air volume unit configuration parameters, chiller device configuration parameters, a rated device capacity, a rated device power, and a rated device speed. The master controller is further configured to control the plurality of slave devices using the slave device configuration information.

Abstract: A building management system includes a communications interface connected to HVAC devices, a device identifier configured to identify the HVAC devices, a fault detector configured to detect a fault condition in the identified devices, and a causal relationship template retriever configured to retrieve a fault causation template of system parameters specific to the fault condition. The building management system further includes a status requestor configured to retrieve operating data from the identified devices and a user interface generator. The user interface generator is configured to populate the system parameters of the fault causation template with the retrieved operating data and transmit a signal to display a user interface with the populated fault causation template on a display screen.

Abstract: A building management system includes a communications bus, an old master controller device; and slave devices. The slave devices are configured to detect that the old master controller device has stopped communicating over the communications bus and to perform an algorithm to determine a new master controller device from the slave devices. The algorithm is based on a device identifier associated with each of the slave devices. The new master controller device is further configured to assume the functions of the master controller device. The functions of the master controller device include transmitting control signals to the slave devices.

Abstract: A building management system includes a communications bus, slave devices connected to the communications bus, a remote server that includes a slave device configuration database, and a master controller connected to the communications bus. The master controller is configured to query the slave devices for device identification codes, receive device identification codes from the slave devices, and connect to the remote server. The master controller is further configured to transmit device identification codes to the slave device configuration database, receive slave device configuration information from the slave device configuration database, and control the slave devices based on the slave device configuration information.
