With the refinements to the quick start example introduced above the resulting
device will do the following:
• Participate in and honor all ISI messages relating to the device’s subnet/node
address.
• Use timing guidance received from a domain address server, if available, and
the application is linked with the IsiCompactS, IsiCompactSHb,
IsiCompactDa, IsiCompactDaHb, or IsiFull library; see
Optimizing the
Footprint of ISI Applications
for more details about the different ISI libraries.
• Open enrollment for connections with a width of 1, offering a connection with
a SNVT_switch network variable.
• Provisionally approve open enrollment messages for manual connections that
relate to a single standard network variable with a matching SNVT_switch
type.
A typical ISI application will proceed and provide further customization. Such
customization serves two purposes:
• A customized application can support more complex connection types, such as
complex compound assemblies or manufacturer-specific connections.
• Customized applications can be tailored to specific application needs.
Customizing ISI can lead to smaller memory footprint, compared to the
generic default implementations.
Further customization is discussed in
Self-Installation Advanced Procedures .
