Use the Local Nv Manager to define nvs and ncis to be available to other networked Lon nodes. Do this using the button at the bottom of the manager, which produces the New dialog (Figure 53). In this dialog, you specify how many to add (and edit) in the subsequent New dialog, and whether these appear as nvs (nvi or nvo) or nci. Typically, you repeat this some number of times, until you have defined the necessary collection of nvis, nvos, and ncis that will act as the Lonworks interface.
If compatibility with Echelon LNS is required, you must create two specific nv entries. See Local Nvs required by LNS for more details.
If you specify Local Nci, direction is always input, whereas if you specify Local Nv, you can set each entry as an nvi or nvo, as needed.
