// enable the trigger counter chunks

Camera.ChunkSelector.SetValue( ChunkSelector_LineTriggerIgnoredCounter );

Camera.ChunkEnable.SetValue( true );

Camera.ChunkSelector.SetValue( ChunkSelector_FrameTriggerIgnoredCounter );

Camera.ChunkEnable.SetValue( true );

Camera.ChunkSelector.SetValue( ChunkSelector_LineTriggerEndToEndCounter );

Camera.ChunkEnable.SetValue( true );

Camera.ChunkSelector.SetValue( ChunkSelector_FrameTriggerCounter );

Camera.ChunkEnable.SetValue( true );

Camera.ChunkSelector.SetValue( ChunkSelector_FramesPerTriggerCounter );

Camera.ChunkEnable.SetValue( true );

To retrieve data from a chunk appended a frame that has been received by your PC, you must first

run the frame and its appended chunks through the chunk parser included in the pylon API. Once

the chunk parser has been used, you can retrieve the counter values from the chunks by doing the

following:

 Read the value of the Chunk Line Trigger Ignored Counter parameter.

 Read the value of the Chunk Frame Trigger Ignored Counter parameter.

 Read the value of the Chunk Line Trigger End To End Counter parameter.

 Read the value of the Chunk Frame Trigger Counter parameter.

 Read the value of the Chunk Frames Per Trigger Counter parameter.

You can run the chunk parser and retrieve the counter values from within your application software

by using the pylon API. The following code snippet illustrates using the API to run the parser and

retrieve the frame counter chunk data:

// run the chunk parser

IChunkParser &ChunkParser = *Camera.CreateChunkParser();

GrabResult Result;

StreamGrabber.RetrieveResult( Result );

ChunkParser.AttachBuffer( (unsigned char*) Result.Buffer(),

Result.GetPayloadSize() );

// retrieve data from the chunks

int64_t LTIgnoredCounter = Camera.ChunkLineTriggerIgnoredCounter.GetValue();

int64_t FTIgnoredCounter = Camera.ChunkFrameTriggerIgnoredCounter.GetValue();

int64_t LTEECounter = Camera.ChunkLineTriggerEndToEndCounter.GetValue();

int64_t FTCounter = Camera.ChunkFrameTriggerCounter.GetValue();

int64_t FPTCounter = Camera.ChunkFramesPerTriggerCounter.GetValue();

For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide

and API Reference.

You can also use the Basler pylon Viewer application to easily set the parameters.

For more information about the pylon Viewer, see Section 3.1 on page 23.
