Systems/methods for intelligent commissioning of an HVAC system provide a control node and at least a first network node coupled to communicate with the control node, the first network node configured to retrieve via a user interface objects configured at the control node, configure at least a second network node using the retrieved objects, and report the configuration of the second network node at the control node. A user interface of a first network node can access the objects at the control node. The first network node can apply the accessed objects to configure a second network node using a commissioning tool. The commissioning tool can be activated specifically for certain authorized HVAC personas or roles. The first network node can report the configuring at the control node. The commissioning tool can be voice-enabled to allow a single user to configure the HVAC system via voice commands.

Intelligent commissioning of building automation controllers

A pressure transducer arrangement and method of operation is provided. The pressure transducer and methods of operation reduce error in determining an offset value by eliminating error relating to fluid flow through the transducer arrangement when the offset value is determined. In a particular embodiment, the apparatus and method includes a lockout valve that prevents fluid flow between first and second fluid pressure sources when the offset value is determined.

BACnet objects and methods for efficiently monitoring the communication status of networks and devices in a building automation and control system are presented. A pair of bus communication status objects, including a server object and a client object, provide the communication status of an MS/TP network as an OCTET String transmitted only upon a change of value (COV) of the communication status of a device on the network. Individual devices may be monitored with a device communication status object, in conjunction with or apart from the bus communication status objects. For MS/TP devices, automatic configuration and monitoring in a controller is provided. For other devices, a user interface is provided through a graphical tool to allow configuration to specify the desired device and/or network for monitoring.
