Applying Triggers

Triggers can only be applied to specific display objects. For more information, see Conditions, Triggers, and Filters.

To set a trigger, a signal and a reference value / signal must be defined. Optionally, a time offset and / or duration can be set.

If both, conditions and triggers are defined in the EATB MATLAB API, EATB Worker MATLAB applies the conditions first. Then, the triggers act on the signal data selected by the conditions.

You can use the following trigger types:

• Triggers based on edges: This trigger acts on only one signal.

• Triggers based on conditions: Two signals, or one signal and a value are compared.

Note
For the chart types interval, hist, or histpie, two parameters are required for a trigger. You can either define a start trigger in combination with a duration, or you can define a start and stop parameter. If not two parameters are defined for the trigger, the last recording is used as fallback stop trigger.

To apply triggers

• In the configuration window of the chart, click Triggers.

• To set signals, operators and time delays, do the following:

  • Select an entry from the "Operator" drop-down menu.

  • Type text in the "Signal" field and "Reference value / signal" field, respectively.

    Depending on your text, the imported signals are listed in a drop-down menu.

  • Optionally, adjust the time offset and / or the duration by clicking the arrows.

• You can add another trigger or delete a trigger by clicking + or x.

• Click Save.
