ConnectDescTemplate_0 is the default connection description. It enables the LonMaker tool to automatically select a smart
connection description that uses the most appropriate message service type and addressing mode for the connection. It cannot be
modified or deleted.
**
Repeated and Repeated with Group Multicast are identical, as are Unacknowledged and Unacknowledged with Group
Multicast. Repeated and Unacknowledged support connections using these connection descriptions in LonMaker networks that
were created with previous releases of the LonMaker tool.
You can view the properties of these pre-defined connections and create new connection descriptions
in the Connection Details dialog box. You can also use this dialog to change the properties of a pre-
defined connection. To access this dialog box, right-click a connector shape, select Properties from
the shortcut menu, and click Properties on the Network Variable Connection dialog box.
Optionally, you can open the LonMaker menu, click LonMaker Options, select Smart Connection
Descriptions from the options category list, and then click Details.
