Checking for Errors and Trouble-
shooting on the Support Software
Error management on the NX Series is based on the methods used for the NJ/NX-series Controllers.
This allows you to use the Support Software to check the meanings of errors and troubleshooting pro-
cedures. The confirmation method depends on the Support Software.

Checking for Errors from the Sysmac Studio
When an error occurs, you can place the Sysmac Studio online to the Controller or the Communications
Coupler Unit to check current Controller errors and the log of past Controller errors.
Refer to the user's manual for the connected CPU Unit or Communications Coupler Unit for information
on checking errors.
Current 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.
Additional Information

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.
