Echelon LonBridg Server - Manual (Page 35)

LonBridge Server User’s Guide 29
The <lon> element is required, and only one <lon> element is allowed per
message.
<set>
The <set> message modifies one or more objects. The LonBridge Server
stores the specified attribute values, and overwrites any existing attribute
values. You cannot delete attributes from an object.
Whenever a <set> message causes any change to an object, the LonBridge
Server broadcasts the <is_pending> message for that object, followed by the
<is> message when the device responds that the change is complete.
This LonBridge Server returns an error if the <set> message fails or if any of
the attribute changes cannot be completed.
Table 6 lists the attributes for the <set> message.

XML Schema for the LonBridge API
To allow you to create well-formed XML documents for LonBridge messages, this
section provides an XML Schema Definition (XSD) that defines the basic syntax
for the LonBridge API. This schema definition does not include definitions for
the object.element message format (see General Message Format on page 24) or
for tracers (see Tracers on page 25).
