How to Add Device Triggers

Article summary

Learn how to set up triggers that integrate devices on the production floor.


"Device Triggers" are triggers that fire when an event happens in a sensor on the production floor that is connected to Tulip.

Using Triggers, you can add external devices from Tulip’s device list to apps. Additional conditions can be added to the trigger based on the data collected from the device.

How to Add Device Triggers

In general, Tulip recognizes three types of device events that trigger an action:

  • A simple device signal (e.g. barcode scanner output)
  • A GPIO signal (e.g. pin changes)
  • An Analog to Digital (ADC) event (e.g. change in voltage)

Device output can be stored in Variables, initiate a specific action or do both.


A device output might be a single value (e.g. a number) or multiple values (e.g several analog outputs). When you create logical conditions with device outputs, use the variable data and not the variable name.

They can be accessed from the ""Machines and Devices" option in the Step Tab of the Context Pane:

Example Device Trigger

Here's an example:


  • "device" "barcode scanner" outputs at "this station"


  • "Data Manipulation" "Store" "Device Output" "data" location: "new_variable"
