Linking design blocks
You can link design blocks to control the workflow of the automation process.
You can link existing design blocks on the Automation Surface, by drawing an arrow
between them. You can also create a new automation block to link to, while drawing the
arrow.
- To link existing automation blocks on the Automation Surface, click and drag an
arrow pointer from one port to another, as shown in the following figure:
Workflow of automation blocks 
Link data ports (blue circles) to other data ports and execution ports (gray circles) to other execution ports. - To create a new automation block and link to it in one step, click and drag the
arrow pointer from an existing design block port to a blank place on the
Automation Surface and release.
Result: For execution ports (gray circles), the Quick add dialog box opens. For data ports (blue circles), the Select action dialog box displays. - Add a new design block to the Automation Surface.
- For execution links, find and double-click the new control in the Toolbox or Palette.
- For data ports, click the More icon and select properties, a method, or an event for the design block.
The design block and the arrow pointer are created. The pointer is not always created for data ports, as not all design block types have an incoming data port, or an appropriate data port for the value selected.The following figure shows the search results for loop components in the Quick add dialog box:Create link to new automation block

- Execution links and data links
Automations use execution links and data links to create the business logic for executing Pega Robot Studio projects.
