NX-series PROFINET Coupler Unit User’s Manual (W623)
Each event log can contain the following number of records. If the number of events exceeds this num-
ber, the oldest events are overwritten.
The Profinet IO Device Terminal retains event logs even if the Unit power supply is interrupted.
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
12-3-4 Event Codes for Errors and Troubleshooting Procedures
on page 12-11 for details on
event codes and error meanings.
Additional Information
When the power supply is turned ON, the PROFINET 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 Profinet IO Device Terminal. This applies to the following errors.
• Errors that occurred before the power supply to the Profinet IO Device Terminal was cycled
for which the causes of the errors remain.
• Errors that occur after the power supply to the Profinet IO Device is turned ON but before it
moves to the Pre-Operational state.
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.
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 Sysmac Studio when
an error occurs.
