Property Description

use the Set function to modify this property
14.2.3 Using the Set Function on a L
ON
W
ORKS
Channel
You can use the Set function to overwrite the configuration of a channel, or to create a new channel.
The input parameters you supply to the function will include one or more elements. Each
element includes a property that specifies a unique channel to be created or
modified.
Each element may also include a series of properties that define the configuration of the new
(or modified) channel. This set of properties is the same whether you are creating a new channel or
modifying an existing channel.
• If you are creating a new channel, you only need to specify the property; all
other properties are optional.
• If you are modifying an existing channel, you must specify the channel’s . If you
do not specify the handle, a new channel is created. All other properties must be filled; otherwise
the values stored in them are erased. The previous section, Using the Get Function on a
L
ON W ORKS Channel, details the properties you can include in the Set function.
You can set multiple channels with a single Set message. However, you should not attempt to create or
write to more than 100 channels with a single call to the Set function.

You can use the Delete function to delete a L ON W ORKS channel on the SmartServer or a channel in an
LNS network database via the LNS Proxy Web service. The Delete function takes an element
with a LON_Channel_Cfg type as its input. The element only needs to include the channel’s
property in the Delete Request as demonstrated in the following code sample:
