1.4.2 Addressing, Binding and Grouping
The available methods for establishing a functional link between a controlling node or
source node and a target node are as follows:
Direct Addressing:
The source node can simply send commands to the
address of the target node. This may be the permanent 64-bit IEEE/MAC
address of the node or a 16-bit network (or short) address allocated to the node
when it joined the network.
Binding:
In a ZigBee PRO network, ‘binding’ can be used to set up this link. An
application on the source node can be bound to an application on the target
node such that commands issued by the source application are always sent to
the target node without needing to specify an address. The source node can be
bound to multiple target nodes.
Grouping:
In a ZigBee PRO network, ‘grouping’ can alternatively be used to
set up this link, particularly when controlling multiple target nodes
simultaneously (e.g. several lights in unison). The target nodes are collected
into a group with an associated 16-bit group address. A target node ‘knows’
which groups it belongs to - this information is held in a table on the node.
When the source node sends a command to a group address, the command is
broadcast to all nodes in the network. A receiving node is able to identify
whether it is a member of the relevant group and only the nodes in the group
react to the command.
