Method and device for communicating change-of-value information in a building automation system

A method of communicating information between automation components operating within a building automation system, the method comprising:

• detecting an indication representing a change-of-value;
• generating a change-of-value update that includes a plurality of change-of-value messages received from a plurality of devices;
• repetitively communicating the change-of-value update in response to the detected indication;
• receiving an acknowledgment of the communicated change-of-value update;
• and
• terminating communication of the change-of-value update in response to the received acknowledgement.

An automation component configured for wireless communication within a building automation system, the automation component comprising:

• a wireless communications component;
• a processor in communication with the wireless communications component;
• a memory in communication with the processor, the memory configured to store computer readable instructions which are executable by the processor;
• wherein the computer readable instructions are programmed to:
• receive at least one change-of-value update via the wireless communications component, wherein the change-of-value update includes a plurality of change-of-value messages received from a plurality of devices;
• storing the at least one change-of-value update corresponding to at least one wireless device;
• and
• communicate the at least one change-of-value update in response to a polling request and repeat the at least one change-of-value update at regular intervals according to a schedule or until a change-of value acknowledgment is received.

A method of communicating information between automation components operating within a building automation system, the method comprising:

• receiving a plurality of change-of-value messages from a plurality of wireless devices, each of the plurality of change-of-value messages representing a wireless device indication;
• storing the received change-of-value messages according to the corresponding wireless device of the plurality of wireless devices;
• and
• communicating a change-of-value update that includes the plurality of change-of-value messages, and repeating the change-of-value update at regular intervals according to a schedule or until a change-of-value acknowledgment is received.
