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/NY-series Control-
lers.
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 details on
how to check 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
Number of Current Errors
The following table gives the number of errors that are reported simultaneously as current
errors in each Unit.
System Units
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.
NX-series System Units User's Manual (W523)
Unit
When these Units are connected to the CPU Unit, since current
errors are managed in the CPU Unit, the number of current errors
is limited by the number of errors for the CPU Units.
For Slave Terminals, since current errors are managed in the
Communications Coupler Unit, the number of current errors is lim-
ited by the number of errors for the Communications Coupler Unit.
