Specify M-file callback function to execute when run-time error occurs
A run-time error event is generated immediately after a run-time error occurs. This event executes the callback function specified for RuntimeErrorFcn. Additionally, a toolbox error message is automatically displayed to the MATLAB® workspace. If an error occurs that is not explicitly handled by the toolbox, then the hardware-specific error message is displayed.
The default value for RunTimeErrorFcn is daqcallback, which displays the event type, the time the event occurred, and the device object name along with the error message.
Run-time error event information is stored in the Type and Data fields of the EventLog property. The Type field value is Error. The Data field values are given below.
Data Field Value | Description |
|---|---|
AbsTime | The absolute time (as a clock vector) the event occurred. |
RelSample | The acquired (AI) or output (AO) sample number when the event occurred. |
String | The descriptive error message. |
Run-time errors include hardware errors and timeouts. Run-time errors do not include configuration errors such as setting an invalid property value.
Usage | AI, AO, Common |
Access | Read/write |
Data type | String |
Read-only when running | No |
The default value is daqcallback.
