StreamingOutputAdd() [4/4]

void StreamingOutputAdd	(	RapidCode::IOPoint *	point,
		bool	on,
		int32_t	ptPointIndex )

Description:

Sets the state of the passed IOPoint to high (true) or low (false) once the controller reaches the specified point index.

Parameters

point	The IOPoint to turn on or off.
on	The value to set the output to. true=>high, false=>low
ptPointIndex	The MotionElementExecutingID at which to set the output. The valid range is from 0 to the last point index of the currently executing streaming move.

Remarks

This function is also available in RapidSequencer.

Part of the Streaming Motion method group.

Sample Code:

IO: Input & Output

      const int TOTAL_POINTS = 4;                   // total number of points
      const int EMPTY_CT     = -1;                  // Number of points that remains in the buffer before an e-stop
      const int OUTPUT_INDEX = 0;                   // This is the index of the digital output that will go active when the user limit triggers.
      const int NODE_INDEX   = 0;                   // The EtherCAT Node we will be communicating with
 
      double[] positions  = { 1.0, 2.0, 3.0, 4.0 }; // These will be the streaming motion 5 positions.
      double[] times      = { 0.5, 0.1, 0.2, 0.4 }; // These will be the streaming motion 5 positions' time. 
      int outputEnableID  = 2;                      // The motion element ID at which to set the output
      int outputDisableID = 3;                      // The motion element ID at which to set the output
 
      // Set up the inputs
      // IOPoint output0 = IOPoint.CreateDigitalOutput(axis, RSIMotorGeneralIo.RSIMotorGeneralIo16);      // Retrieve DOUT 1, Method 1: requires you know the io adress in memory, slightly faster
      IOPoint output0 = IOPoint.CreateDigitalOutput(controller.NetworkNodeGet(NODE_INDEX), OUTPUT_INDEX);          // Retrieve DOUT 1  Method 2: only need to know node index
      output0.Set(false); // Set the output low
 
      // Set up Sync Outputs
      axis.StreamingOutputsEnableSet(true);                                                               // Enable streaming output.
 
      // ENABLE the Sync Output(s)
      axis.StreamingOutputAdd(output0, true, outputEnableID);                                             // This will turn DOUT1 High when the streaming motion reaches its 3rd motion point.
      axis.StreamingOutputAdd(output0, false, outputDisableID);                                           // This will turn DOUT1 Low when the streaming motion reaches its 4th motion point.
 
      // DISABLE the Sync Output(s)
      // axis.StreamingOutputAdd(output0, false, outPutEnableID);
 
      axis.MovePT(RSIMotionType.RSIMotionTypePT, positions, times, TOTAL_POINTS, EMPTY_CT, false, true);  // Start Streaming Motion
 
      while (!axis.MotionDoneGet())
      {
        if (axis.MotionIdExecutingGet() > outputEnableID && axis.CommandPositionGet() < outputEnableID)
        {
          Assert.AreEqual(output0.Get(), true, "The output should be triggered");
        }
        else
        {
          Assert.AreEqual(output0.Get(), false, "The output should NOT be triggered");
        }
      }
 
      axis.StreamingOutputsEnableSet(false);                                                              // Disable Sync Outputs.
      axis.AmpEnableSet(false);                                                                           // Disable the motor.
