10-3 Checking for Errors and Trouble-
shooting on the Sysmac Studio
Error management on the NX Series is based on the methods used for the NJ/NX-series Controllers.
This allows you to use the Sysmac Studio to check the meanings of errors and troubleshooting proce-
dures.
When an error occurs, you can place the Sysmac Studio online to the Controller or the EtherCAT Cou-
pler Unit to check current Controller errors and the log of past Controller errors.
Refer to the user’s manual for the connected Communications Coupler Unit for information on checking
errors.
Open the Sysmac Studio’s Controller Error Tab Page to check the current error’s level, source, source
details, event name, event codes, details, attached information 1 to 4, and correction.
Errors in the observation level are not displayed.
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. The errors that occur
beyond this limit are not reported.
Errors that are not reported are still shown in the error status.
You can check the following information on past errors on the Controller Event Log Tab Page in the
Sysmac Studio: times, levels, sources, source details, event names, event codes, details, attached
information 1 through 4, and corrections.
Number of Events in Log of Past Errors
The following table gives the number of events that each event log can record. The oldest
events are overwritten if there are more than 15 events in the system event log or two events in
the access event log.
