Execution Output

The Execution Input block is used inside sub-flows to define where the execution should begin when the sub-flow is called. It acts as the starting point and connects to the first functional block within the sub-flow.

When a sub-flow is invoked, the flow begins at the Execution Input block and continues through the connected logic path.

The Execution Output block shows the following properties:

Quick-start

1. Drag Execution Input onto the sub-flow canvas.
2. Connect the output of the Execution Input block to the block that should receive the execution input within the sub-flow.
3. Run the main flow that references this sub-flow.

Parameters
