Echelon LNS - Manual (Page 115)

LNS Programmer's Guide 101
• You should be aware that in some cases, remote Full client applications cannot
open networks when the system management mode is set to
lcaMgmtModeDeferConfigUpdates. This may be the case if the Full client
application has not previously connected to the LNS Object Server, if the Full
client application has changed channels, or if changes have been made to the
database such that commissioning the Network Service Device may cause
inconsistencies in the configuration of physical devices on the network.
Use the AllowPropagateModeDuringRemoteOpen property to determine how
LNS will behave in this situation. Set the property to True if it is acceptable for
LNS to temporarily change the system management mode from
lcaMgmtModeDeferConfigUpdates to
lcaMgmtModePropagateConfigUpdates when opening a network from such a
client application in these situations. Otherwise, set this property to False.
You should note that when this property is set to True and the system
management mode is changed, all pending configuration updates will applied to
the physical devices on the network. This may result in unwanted changes being
propagated to the network. Once this has completed and the network has been
opened, the management mode will be restored to
lcaMgmtModeDeferConfigUpdates.
