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.

state Specifies the state for the device. Optional

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).
