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 US at voltage input X70 "IN". |
2 | Undervoltage Up | Undervoltage of UP at voltage input X70 "IN". |
3 | Overtemperature | Internal temperature too high. |
4 | Overcurrent | The overload switch-off of an EtherCAT P port has switched off an output voltage. |
5 | FoE Transfer | The data upload was started before the recording was stopped. |
6 | Hardware Protection | The starting current limitation of an EtherCAT P port has switched off an output voltage. |
7 | User Stop Bit | Set the bit "Stop Logger" in the process data. |
255 | Logger still running | N/A. |
