Name	Description	Return type
MLTrigClearFlag	Clears the flag of an initiated Trigger block	BOOL
MLTrigInit	Initializes a Trigger object	BOOL
MLTrigIsTrigged	Checks if the selected block has been triggered	BOOL
MLTrigReadDelay	Returns the time that the trigger block uses to compensate the delay of the sensorA sensor is a type of transducer that converts one type of energy into another for various purposes including measurement or information transfer that captures the triggering signal	None
MLTrigReadPos	Returns the position of the block at the moment when it was triggered	None
MLTrigReadTime	Returns the time of the moment where the block was triggered in milliseconds	None
MLTrigSetEdge	Sets the edge configuration for a Trigger object	BOOL
MLTrigWriteDelay	Sets the time that the trigger block uses to compensate for the delay introduced by the sensor that captures the triggering signal	BOOL

Usage example of Trigger Functions

When you call the MLTrigClearFlag function, the flag for trigger is reset to False.

When a Fast Input is set, the MLTrigIsTriggered function returns True.

Then you can call the MLTrigReadPos and MLTrigReadTime functions to get more details.

• 
  

• The trigger delay has to be calculated by you and set with the MLTrigWriteDelay function block.
  This delay belongs to the sensor and it is additional to the MLTrigReadTime / MLTrigReadPos.
