Retaining Event Logs during Power Interruptions
The EtherNet/IP Slave Terminal retains event logs even if the Unit power supply is interrupted.
Event Codes
Event codes are pre-assigned to the events based on the type of event. Event codes are displayed as
8-digit hexadecimal numbers.
Refer to 12-3-5 Event Codes for Errors and Troubleshooting Procedures on page 12-22 for details on
event codes and error meanings.
Additional Information
When the power supply is turned ON, the EtherNet/IP Coupler Unit resets any current errors
and detects errors again. Therefore, the same error may be recorded more than once in the
event log of the EtherNet/IP Slave Terminal. This applies to the following errors.
• Errors that occurred before the power supply to the EtherNet/IP Slave Terminal was cycled
for which the causes of the errors remain.
• Errors that occur after the power supply to the EtherNet/IP Slave Terminal is turned ON but
before it moves to the Pre-Operational state.
Event Levels
Each event has an event level.
Events are classified into the following five levels according to the level of impact the events have on
control.
No. Event level
1 High
2
3
4
5 Low
Errors with a higher level have a greater affect on the functions that the complete system provides, and
it is more urgent to recover from them. These classifications are displayed on the Support Software
when an error occurs.
