# Configuring a Sub Task Block

After a Sub Task block has been added to a project, input and output pins for the block can be configured.

- If the Sub Task block was created from existing blocks, the input and output pins will have been automatically configured. The order of the pins can then be modified, and new pins can be added, and existing pins can be removed.
- If the Sub Task block was added by from the Toolbox, the input and output pins will have to be configured by adding the desired pins.

To configure the pins of the Sub Task block, use the right-click menu while either selecting a Sub Task block in a Task, or selecting the input or output block of a Sub Task, and selecting Configure Sub Task I/O, which will launch the Configure Sub Task Input/Output Pins dialog.

Note: While in a Task containing a Sub Task block, you can either double-click the Sub Task block or select and choose Edit from the right-click menu to open the Sub Task block's Task Editor.
