Delay

Overview

Pauses the flow for a specific duration before passing the input data to the output. This is typically used to add necessary wait times between operations.

Use Delay when:

• Waiting for a hardware component to settle after a command.

Inputs

Name	Type	Description
input	any	The data to be delayed.

Outputs

Name	Type	Description
output	same as input	The original input data, emitted after the delay.

Parameters

Parameter	Default	Valid values	Unit	Tunable
Wait time	1	0 – unlimited	s	✅
Wait always	true	true, false	-	❌

Wait time

The amount of time to pause the flow in seconds.

Wait always

Determines the delay behavior. If true, the node pauses every time it receives an input. If false, it only delays the first time it is executed in a session.

Example

Settling time

Wait 2 seconds for a camera to adjust its focus before capturing an image.

Configuration:

• Wait time: 2.0
• Wait always: true

Result: The input signal is held for 2 seconds before being passed to the next node.
