Error Codes#

The Error Codes camera feature allows you to read error codes from the camera.

If several different errors occur, they are stored in an error list and can be retrieved one by one.

Using the Feature#

How It Works#

The camera can detect certain errors. If such an error occurs, the camera assigns an error code to this error and stores the error code in memory.

If several different errors occur, the camera stores the code for each type of error detected. The camera stores each code only once regardless of how many times it has detected the corresponding error.

Checking Error Codes#

Checking error codes is an iterative process, depending on your camera model and how many errors have occurred.

ace 2, boost, dart M/R, and racer 2 Cameras#

Basler ace 2, boost, dart M/R, and racer 2 cameras can generate a list of errors that can be evaluated by Basler support.

To check error codes on ace 2, boost, dart M/R, and racer 2 cameras:

1. Get the value of the BslErrorPresent parameter.
2. If the parameter value is true:
   1. Get the value of the BslErrorReportValue parameter.
   2. Store the value on your computer or write it down for further reference.
   3. Execute the BslErrorReportNext command. This retrieves the next error code from the device.
   4. Repeat steps a) to c) until the BslErrorReportValue parameter value is 0. A parameter value of 0 means that there are no more error codes to retrieve.
   5. Contact Basler support with the list of error codes.

ace U/L Cameras#

Basler ace U/L cameras can generate a list of errors that can be corrected by yourself or evaluated by Basler support.

To check error codes on ace U/L GigE cameras:

1. Get the value of the LastError parameter.
2. Store the value on your computer or write it down for further reference.
3. Execute the ClearLastError command. This deletes the last error code from the list of error codes.
4. Repeat steps 1) to 3) until the LastError parameter value is NoError.
5. Troubleshoot the errors using the table below or contact Basler support with the list of error codes.

Available Error Codes#

The following table applies to Basler ace U/L cameras only.

Sample Code#

ace 2, boost, dart M and dart R Cameras#

// Check whether an error occurred on the device
bool errorPresent = camera.BslErrorPresent.GetValue();
// Get the first error code
int64_t errorReportValue = camera.BslErrorReportValue.GetValue();
// Retrieve the next error code from the device
camera.BslErrorReportNext.Execute();

INodeMap& nodemap = camera.GetNodeMap();
// Check whether an error occurred on the device
bool errorPresent = CBooleanParameter(nodemap, "BslErrorPresent").GetValue();
// Get the first error code
int64_t errorReportValue = CIntegerParameter(nodemap, "BslErrorReportValue").GetValue();
// Retrieve the next error code from the device
CCommandParameter(nodemap, "BslErrorReportNext").Execute();

// Check whether an error occurred on the device
bool errorPresent = camera.Parameters[PLCamera.BslErrorPresent].GetValue();
// Get the first error code
Int64 errorReportValue = camera.Parameters[PLCamera.BslErrorReportValue].GetValue();
// Retrieve the next error code from the device
camera.Parameters[PLCamera.BslErrorReportNext].Execute();

ace U/L Cameras#

// Get the value of the last error code in the memory

// Clear the value of the last error code in the memory
camera.ClearLastError.Execute();

INodeMap& nodemap = camera.GetNodeMap();

String_t lasterror = CEnumParameter(nodemap, "LastError").GetValue();
// Clear the value of the last error code in the memory
CCommandParameter(nodemap, "ClearLastError").Execute();

// Get the value of the last error code in the memory

// Clear the value of the last error code in the memory

size_t len = 0;
char lasterror_str[64] = {0};
/* Get the value of the last error code in the memory */

errRes = PylonDeviceFeatureToString(hdev, "LastError", lasterror_str, &len);
CHECK(errRes);
/* Clear the value of the last error code in the memory */
errRes = PylonDeviceExecuteCommandFeature(hdev, "ClearLastError");
CHECK(errRes);

# Get the value of the last error code in the memory
lasterror = camera.LastError.Value
# Clear the value of the last error code in the memory
camera.ClearLastError.Execute()

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