Troubleshooting with the data logger

You can use the data logger to determine the cause of an error, among other things. The prerequisite for this is that the recording of the measured values is already enabled when the error occurs.

Determine the cause of the error

The data logger stops recording the measured values if an error occurs, among other things. The reason for the last stop of the recording is output in the process data and via a CoE parameter:

PDO "Log Status" > "Trigger Reason"
CoE parameter 6040:12 "Trigger Reason"

Possible values:

Value	Enum text	Reason for stopping the recording
0	Undefined	Unknown.
1	Undervoltage Us	Undervoltage of U_S.
2	Undervoltage Up	Undervoltage of U_P.
3	Overtemperature	Internal temperature too high.
4	Overcurrent	The overload switch-off has switched off an output voltage.
5	FoE Transfer	The data upload was started before the recording was stopped.
6	Hardware Protection	Thermal shutdown of an output voltage after current limitation.
7	User Stop Bit	Set the bit "Stop Logger" in the process data.
255	Logger still running	N/A. The recording has not yet been stopped.
