this property exists for an object as soon as the object is

ParentInterface

Summary

Returns the

Interface

object to which the

NetworkVariable

Object belongs

.

Each

AppDevice

on a network contains an

Interface

property

containing the device’s main interface, and an

Interfaces

collection containing the custom interfaces that have been

added to the device dynamically. The interfaces each contain

network variables and LonMarkObjects that reflect the

device’s functionality on the network.
The ParentInterface property returns the

Interface

object to

which the

NetworkVariable

Object belongs. In the case of

static LonMarkObjects and network variables, this property

returns the main device interface or device template the

object is associated with. In the case of a dynamic

LonMarkObject

and network variables, it returns the custom

interface to which the object belongs.
The ParentInterface property is read-only. However, you can

move a dynamic network variable or

LonMarkObject

from

one custom interface to another with the method.

Availability

Local, full, and lightweight clients.

If the network variable is a connected output network

variable, or a polling input network variable, then this flag

will be used to determine whether messages sent by the

network variable use priority. This value may be overridden

by the

UsePriorityFlag

property of the network variable’s
