Glossary of Terms
Association -
The linking together of two nodes (units) so that one node will send information to the other node. The node
doing the sending is the source and the node receiving the information is the destination.
Group -
A set of one or more modules that are to be operated together as if they were one device. More specifically, every
module that is included in a group will switch on or off together as that group is turned on and off. When a group is activated,
each Light or Lamp module in that group turns on, returning to its last dim level - a level that in general, will differ from module
to module. Appliance Modules may also be included in groups. There are 64 Z-Wave lighting Groups in the Z-Wave protocol.
Node (Unit)
- A single Module entity within the Z-Wave network. It could be a Plug-in Dimmer Module, Appliance Module, Wall
Switch, Wall Dimmer, etc. There are 160 addressable Z-Wave unit nodes as described in the Z-Wave protocol.
Scene
- To link or 'associate' one or more modules, except that the controller stores not only the association, but also the dim
level for each Module. The dim level is stored at the time that a Module is added to a scene. Consequently, when a scene is
activated, the Modules will all go to their previously defined dim levels regardless of what their most recent dim level may have
been. Some Modules may get brighter while others may be pre-programmed by the user to become dimmer. Because
Appliance and Wall Switch Modules are switching devices without dimming capability, they will either be defined as on or off
when added to a scene. There are 32 Z-Wave lighting Scenes in the Z-Wave protocol. Each Scene can have a maximum of
58 Nodes or individual devices assigned it.
Replicate -
To transfer or copy the setup and configuration information between a handheld Primary Controller and a Second-
ary Controller.
Route
- If an obstacle or radio dead spot exists between two Z-Wave modules, Z-Wave automatically repeats or passes the
signal from one device to the next, effectively going around obstacles and radio dead spots in a building. Like wise, if two
devices are not within range of one another, a route can be manually assigned to the source module (the module sending the
information). This essentially enables devices to communicate at long ranges since the signal is repeated or "bounced" until
it reaches the receiving module.
Status Reply
- The process of a device transmitting its current state (on, off, dim, etc.) in response to an individual node or unit
change command from a controller. At the present time, Z-Wave devices ONLY respond with their status to the specific
controller that commanded their change. Secondly, Z-Wave devices DO NOT respond with their status when a Group or
Scene command is issued. Z-WAVE DOES NOT BROADCAST STATUS CHANGES TO OTHER CONTROLLERS WITHIN THE
NETWORK.
