Links between CPM and VPM
The following kinds of links can be made between a VPM task or tool and a CPM control:
• Get Data Link: a CPM control property receives data from a VPM tool or task property
• Set Data Link: a CPM control property sends data to a VPM tool or task property
• Method Link: a CPM property sends data to a VPM tool or task method property such as Run or Train
• Data Transfer Link: a CPM control property receives data directly from a VPM Data Transfer tool
Create Drag and Drop Links to VPM
There are two ways to create a link between VPM and CPM. You can use left-click drag and drop, or right-
click. This section describes how to create drag and drop links. See “Create Right-Click Links to VPM” on
page 4-18 for right-click links. When you create a drag and drop link from VPM to CPM, CPM will auto-
matically add a new control if needed, or give you the option to link to the appropriate property type in an
existing control. The type of control added, or the property choice shown, depends on the type of data you
are linking.
Drag and Drop - Control Added
This section describes the kind of new control that is added to a Control Panel when you create a link to a
blank area on the Canvas or the Control Tree.
Get Data
To create a Get Data link, select the desired property in VPM with the left mouse button, then drag and drop
it onto an empty spot on the Control Panel Canvas or the Control Panel Tree. This table lists the default con-
trol added for a left-click drag and drop Get Data link.
