Data Tag Triggers

A data tag can be associated with many different triggers. Triggers can be used to trigger an event to be raised (e.g. raise event equipment status starved when rpm value is greater than 250). A trigger will only raise this event when the evaluation script for the trigger is true for the first time. It will not be able to trigger again until the evaluation script is false again.

Navigate to the edge data tag and find the table with the title Edge Trigger. Find the create button on the top right.

1. Click the +Create button; this will open a new pop-up config window.

2. In the pop-up window, complete the following:

   • 
   • Event Type - The desired event that should be raised when the trigger is triggered

   • Evaluation Script - The cause for the trigger to activiate where 'value' is the value of the tag at evaluation (see more here)

     • e.g. value > 1, 5 < value && value < 20 , value == 8

   • Active - If you want to include this trigger in the poll cycle. Setting to inactive will cause TilliT Edge to not evaluate the trigger.

   • Minimum Duration - Specify how long (in minutes) the evaluation script must be true before TilliT Edge triggers the chosen event. Setting to 0 will trigger the event immediately upon the evaluation script being true

   • Requires Running Order - Will only raise the trigger if the order is running. This is useful in scenarios where the evaluation script is true while an order is not running. WIth this set to true, the event will only raise once the order becomes running.

3. Click Save and close".
