Variable (Lon component) management

Communication between nodes on a Lon Network uses network variables (inputs and outputs), which must be defined for each node (device). Multiple nodes share these variables. Some variables send information, while others receive. Lon networks link only devices whose network variables are of the same type.

Variables have manager views, including the Local Nv Manager view, which you open by double-clicking the Local Lon Device node in the Nav tree, and the Nv Manager and Nc Manager, which you open by right-clicking a DynamicDevice in the Nav tree, and clicking Views > Nv Manager or Views > Nc Manager.

Variables cannot be discovered. Instead, you add them as needed. In general, you should finalize the creation of the nvis, nvos, and ncis variables before you add associated proxy points. This means reviewing and, if necessary, editing the name, direction, and SNVT for each entry.

Following this initial configuration, if you change, add to, or delete from the definition of any network variable, you need to perform (external) network management on the host node to maintain proper network configuration. This includes maintenance of any bindings to the host.
