element.

If this method is called while not attached to the network,

this message will throw an exception. Ignore it and call the

PostMove method to move a device while in engineered mode.

See the PostMove method for more information on the steps

required to move an application device.

PropagateDeviceConfigUpdates

Summary

Propagates any pending configuration changes to the

physical device associated with this AppDevice object.

The network management mode can be set to one of two

values: lcaMgmtModePropagateConfigUpdates (0), or

lcaMgmtModeDeferConfigUpdates (1). When it is set to

lcaMgmtModeDeferConfigUpdates (1), all network

configuration changes caused by your application will only be

applied to the OpenLNS database, and not to the physical

devices on the network.

Prior to LNS 3.20, these changes would be queued and then

applied to all the physical devices as soon as the network

management was set back to

lcaMgmtModePropagateConfigUpdates (0).

However, in LNS 3.20 and beyond, you can use this method

to apply device-only configuration changes to a physical

device without changing the network management mode

back to lcaMgmtModePropagateConfigUpdates (0). This

may be useful if you have configuration changes pending for

a large number of devices, and only want to apply them to a

subset of those devices. The device-only configuration

information propagated by this method includes

configuration property values and the device location string.

It does not include information such as network variable

configurations, address table entries and connection

information.

If you invoke this method and OpenLNS determines that it

cannot safely propagate the changes to the physical device,

the operation will fail, and the NS, #4039
