that specified by the application, and the program interface
in the device matches the previously defined program
interface for that program ID. This validation occurs to
prevent users from configuring a device incorrectly.
This validation, however, does require the transmission of a
large number of messages between OpenLNS and the device.
This can be very time consuming, particularly on slow media,
and can greatly increase the time required to commission the
devices on a network.
You can use this property to determine which validation
steps OpenLNS will perform when you are commissioning,
replacing or upgrading a device.

Element Description
validationOption The validation options used when
commissioning or replacing devices
that use this device template.
The valid settings for this property,
which are contained in the
ConstDeviceValidation constant, are
as follows:
0 lcaDeviceValidationNormal
This is the default value. When this
value is used, all validation steps
will be performed.
In this case, the commission
procedure will validate that the
physical device has the same
external interface and program ID as
defined for the AppDevice object in
the OpenLNS database. It will also
validate that the device is on the
channel assigned to it in the
OpenLNS database.
If the physical device is not using the
same external interface or program
ID as defined for the AppDevice
object in the database, the
commission will fail, and either the
NS, #59
lcaErrNsProgramIntfMismatch
or NS, #38
lcaErrNsProgramidMismatch
exceptions will be thrown.
If the physical device is not on the
channel assigned to it in the
