Segundo a documentação do protocolo BACnet:

defines a standardized object used to forward a single received value to a collection of object properties. The collection of object properties may include any combination of object types, as well as properties of different data types. Each Channel object is associated with a single logical "channel" in the range 0..65535. Multiple Channel object instances may be associated with a given channel number. Each Channel object may be a member of zero or more "control groups" to facilitate writing to Channel objects with the WriteGroup service. The Channel object is intended for value distribution and does not maintain a state. Therefore, it does not act on its own and does not contain a priority array. When the Present_Value property of this object is written by the WriteProperty, WritePropertyMultiple, or WriteGroup services, and a 'Priority' is provided in the write, this object shall use this same priority to command the referenced properties.
