LonMaker User’s Guide 297
Default Plug-In Registers the plug-in as the default application for the specified
command and object class. The LonMaker tool removes the
default attribute, if set, from all other plug-ins registered for that
command and object class. If this check box is cleared, the
LonMaker tool does not change the attribute on any other plug-
ins.
If multiple plug-ins are registered for the same command and
object class, the plug-in with this check box selected will be the
one invoked. If multiple plug-ins have this check box selected,
the LonMaker tool invokes the first plug-in that it finds with this
option set.
Prelaunch Keeps one instance of the plug-in program pre-launched (if
registered) so that it is immediately available for commands that
invoke it.
When you select or clear this check box, the LonMaker tool will
select or clear it for all LonMaker networks on your computer. If
you clear this option, the change is not effective until you close
and then re-open the network.
If the plug-in does not support pre-launch capability, this
checkbox is disabled.
Settings
Multiple Objects Indicates whether the plug-in supports multiple objects. For
example, the LonMaker Browser supports browsing multiple
functional blocks.
Single Instance Indicates whether the plug-in supports using a single instance of
the plug-in when it is requested for the same object multiple
times.
Description Provides a brief description of the plug-in.
Click OK to return to the LonMaker Plug-ins dialog.
Viewing Plug-in Status
You can view the status of plug-ins that the LonMaker tool has launched and to which it still holds a
reference. The LonMaker tool holds a reference to a plug-in after launching one if the plug-in was pre-
launched, and it is a single-instance, multi-object plug-in. When the LonMaker tool holds a reference
to a plug-in, it will typically prevent the plug-in from being terminated unless you release the plug-in.
To access the LNS Plug-in Status dialog, open the LonMaker menu, point to Plug-Ins, and then
click Plug-In Status.
