StreamingOutputsClear()

void StreamingOutputsClear

(

)

Description:

This method will clear the contents of the Streaming Output List – to be used when finished with Streaming Outputs or when preparing to append motion points with new Streaming Outputs

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.That(output0.Get(), Is.EqualTo(true), "The output should be triggered");
        }
        else
        {
        Assert.That(output0.Get(), Is.EqualTo(false), "The output should NOT be triggered");
        }
      }
 
      axis.StreamingOutputsEnableSet(false);                                                              // Disable Sync Outputs.
      axis.AmpEnableSet(false);                                                                           // Disable the motor.
