NetworkVariable
object represents a single instance of a network variable.
This object is used to represent a network variable that actually appears in an
object's interface, or that is part of a
program interface definition.
•
If a NetworkVariable object is accessed through a DeviceTemplate object, it represents a
network variable that is part of a program interface definition. In this case, some of the
methods and properties do not apply to the object. For example, it is not possible to read
the value of a network variable that is accessed through a DeviceTemplate .
•
If a NetworkVariable object is accessed through the Interface property of an AppDevice
object, it represents a network variable defined on that device’s interface. It may also
represent a connection hub, depending on how you have used the network variable in
connections. The NetworkVariable objects that are being used as connection hubs can be
accessed through the NetworkVariables collection contained by the NVHubs property of
an AppDevice object. You can use this collection to determine which network variables on
a device are being used as connection hub.
The following table summarizes the NetworkVariable object.
