Debug Log Feature Overview

Debug Log is enabled by setting DebugLogTarget, which is a DncDaq property.

When Debug Log feature is enabled, the Debug Log is displayed at the timing at which the Debug Log is added, and the debug log file is saved.

Sets the debug log file save destination and file switching lines by DebugLogFileName, DebugLogFileRecordNum.

Error Log

This log is output when it is determined that an error in DncDaq.

For the device No., the error type, the error parameter, etc., please refer to About OnError event.

Format	YYYY/MM/DD HH:MM:SS [ERROR] Position[DeviceNo] : [Error type(Error parameter)]
Log Example	[ERROR] (DncDaq).Init[-1] : (Cate)21 (Type)3 (Error)510001 (Param)16

Exception Log

This log is output when an exception error occurs in DncDaq.

Format	YYYY/MM/DD HH:MM:SS [EXEPTION] Position : [Exception output message]
Log Example	2022/02/15 15:00:50 [EXEPTION] (DncDaq).on_aio_continuous_mode_start[0] : Object reference not set to an instance of an object.

Usually, it does not occur, but it may occur, for example, in the following situations.

If an exception error occurs in the DncDaq event handler

The process described in the DncDaq event handler is executed as a DncDaq callback function.
If an exception occurs during callback function execution, Dnc catches the corresponding exception message and outputs as a log.

In the log example, shows an example of the null reference in the device No.0 OnAioContinuousStart event.
