source details, event name, event codes, details, attached information 1 to 4, and correction.
Errors in the observation level are not displayed.
Additional Information
Number of Current Errors
The following table gives the number of errors that are reported simultaneously as current
errors in each Unit.
If the number of errors exceeds the maximum number of reportable current errors, errors are
reported with a priority given to the oldest and highest-level errors. Errors that exceed the limit
on simultaneous error notifications are not reported.
Errors that are not reported are still reflected in the error status.
Open the Sysmac Studio's Controller Event Log Tab Page to check the times, levels, sources,
source details, event names, event codes, details, attached information 1 to 4, and corrections for
previous errors.
Refer to the NJ-series Troubleshooting Manual (Cat. No. W503) and the Sysmac Studio Version 1
Operation Manual (Cat. No. W504) for the items that you can check and the procedures to check for
errors. Refer to 11-5 Event Logs on page 11-12 for details on the event log in the Slave Terminal.
Refer to 13-3-2 Event Codes for Errors and Troubleshooting Procedures on page 13-14 for details on
event codes.

Error Notifications for Slave Terminals
The NJ-series Controller can use the Sysmac error status to detect errors that occur in an EtherCAT
Slave Terminal. Refer to
13-6 Error Notifications Based on the Sysmac Error Status on page 13-42
for details on the Sysmac error status.

NX Units For NX Units that manage their own current errors, the number of
current errors depends on the specifications of the individual
Units.
For NX Units that do not manage their own current errors, current
errors are managed in the EtherCAT Coupler Unit, so the number
of current errors is limited by the number of errors for the Ether-
CAT Coupler Unit.
Refer to the manual for each NX Unit to find out if the NX Unit
manages its own current errors.
