When you create a sequence of commands to send to a device, you build up a matrix of script nodes. You can add nodes, into your script, from the Script Nodes docked window or from the Predefined CDBs docked window.
After a script node completes its operation, the script needs to determine which node it should move to next. For example, if an executed CDB completes successfully, you may want the script to branch to a different node than it would if the CDB completed with some failure. That is where Node Links are used. When a script node completes, depending on which conditions are met, the script will take a Node Link to determine which node to branch to next as the script continues to execute.
When you double-click on a script node (in the script matrix window), you click on the Node Links tab to view the node links configured for the selected script node. In this screenshot, the Display Message script node has been configured with two Node Links. One to branch on if the user chooses OK, the other to branch on if the user chooses Cancel.
You can click on the color indicator (with the drop arrow to its right) to change the color you would like to use to mark the node link. The following toolbar buttons are available to help you adjust the Node Links.
In addition to using the toolbar, you may prefer to right click on the node links to view the same options.
In the screenshot we see above, we added a Branch on "OK" Selected (green color indicator) and a Branch on "Cancel" Selected (red color indicator) node link. When you select OK and view the script matrix, you will see that the Display Message script node now has two node link indicators at the very bottom of the script node graphic.
To let the script know which script node the link should branch to, move the mouse over the node link indicator and drag and drop it onto the script node you want it to link with. For example, this next screenshot shows that we configured the script to branch to a Test Unit Ready CDB if the user clicked on OK, and an Inquiry CDB if the user clicked on Cancel.
As you float the mouse over the node link indicator, a tooltip will appear letting you know what the link is as well as animating the link path. You can also right click on the node link indicator to view additional options.
