RecorderConfigureToTriggerOnMotion() [3/5]

void RecorderConfigureToTriggerOnMotion	(	int32_t	recorderNumber,
		int32_t	motionNumber,
		bool	triggerOnMotion )

Parameters

recorderNumber	The number of the recorder to configure.
motionNumber	The motion number to use. Axis::NumberGet() or MultiAxis::NumberGet().
triggerOnMotion	A boolean value to set the trigger state. TRUE = trigger on Motion.

Description:

RecorderConfigureToTriggerOnMotion sets the recorder to trigger on motion. The recording will start when motion begins, and it will automatically stop when the Motion Done condition is true.

Part of the Recorder method group.

Sample Code:

      const int VALUES_PER_RECORD     = 2;    // How many values to store in each record.  
      const int RECORD_PERIOD_SAMPLES = 1;    // How often to record data. (samples between consecutive records)
      const int RECORD_TIME           = 250;  // How long to record. (in milliseconds)
      const int INPUT_INDEX           = 0;
 
      // Get the host controller addresses for the values we want to record         
      // Number of processed Recorders in the controller.
      controller.RecorderCountSet(1);
 
      controller.AxisCountSet(1);
      Axis axis = CreateAndReadyAxis(Constants.AXIS_NUMBER); // Helper function to setup an axis
 
      UInt64 userBufferAddress = controller.AddressGet(RSIControllerAddressType.RSIControllerAddressTypeUSER_BUFFER, 0); // Grabing an memory address to store a simulated IO point.
      // Instead of using physical IO we will use simulated IO using a memory address as simulated IO. See the IO sample apps to see how to use a physical IO instead. 
      IOPoint input = IOPoint.CreateDigitalInput(controller, userBufferAddress, INPUT_INDEX);    // Create a simulated IOpoint using userBuffer memory. 
 
      if (controller.RecorderEnabledGet() == true) // Check if the recorder is running already. If it is, stop it.

      for (int i = 0; i < recordsAvailable; i++)                                // Check every record recorded.
      {
