OpenLNS CT User’s Guide 297
OpenLNS CT 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,
OpenLNS CT invokes the first plug-in that it finds with this
option set.
Prelaunch Keeps one instance of the plug-in program active (if registered)
so that it is immediately available for commands that invoke it.
When you select or clear this check box, OpenLNS CT will
select or clear it for all OpenLNS CT 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 check
box is disabled.
Settings
Multiple Objects Indicates whether the plug-in supports multiple objects. For
example, the OpenLNS CT 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 OpenLNS CT Plug-ins dialog.
Viewing Plug-in Status
You can view the status of plug-ins that OpenLNS CT has started and to which it still holds a
reference. OpenLNS CT holds a reference to a plug-in after starting one if the plug-in was
pre-launched, and it is a single-instance, multi-object plug-in. When OpenLNS CT 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 OpenLNS Plug-in Status dialog, click Add-ins, point to Plug-Ins, and then click
Plug-In Status.
The columns contain the following data. You can sort the data by clicking a column header. Click a
header again to toggle the order (ascending or descending) in which the data in that column opens.
