This information is also found in the UCM/Zwave Manual which can be downloaded from http://www.cytech.biz/ucmzwave_manual.html

Zwave Nodes
The Z-Wave network can have up to 232 nodes. Each Network has a 32-bit Home ID. Nodes can be either Controllers, or Slaves.

Controllers can be either Primary or Secondary. There can be only 1 Primary controller which is usually a remote control or PC-based device, whose role is to set up and manage the network.  Secondary controllers receive the network information from the primary controller.

Z-Wave Slaves nodes are either Basic or Routing Slaves. Routing Slaves are able to transmit information or commands to other Z-Wave enabled devices without being requested to do so while Basic slaves can only send information when requested to do so. For example a Z-wave appliance module which is a basic slave may have a local  button to toggle switch the connected device, but this will not send the status information to the network, whereas a Routing Slave will be able to do so.
Each node on the network is assigned a Node ID by the Primary Controller
The UCM/Zwave3 is a Secondary Controller in the Z-Wave network and has a  Bridge Controller function. A Bridge Controller is a static controller that is able to represent  up to 128 Virtual Nodes in the Z-wave Network. Note that Virtual Nodes will reduce the nodes available for the rest of the network, as the total number of nodes are limited to 232. Virtual Nodes are assigned to the UCM/Zwave3 which act as Slave nodes, allowing controllers and Routing Slaves to send commands or information to the virtual node.

Z-Wave Operations and Terminology
The following operations must be performed by the primary controller.

Inclusion
A new Z-Wave device must first be included in a Z-Wave network by the Primary controller. It is assigned a Node ID.
Replication
This is the process of copying the network information (Ids and routing) from a Primary to a Secondary Controller.
Association
This is the process of linking a source Z-Wave ID  (controller or routing slave) to a target ID (Slave) so that pressing the controller or routing slave button controls the slave.  Many Z-Wave Ids can be associated to a Slave.
Disassociation
This is the process of removing the association between source and target.
Exclusion
This is the process of removing a Zwave Node from a network.
