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 that is used.
5-3-1
Checking for Errors from the Sysmac Studio
When an error occurs, you can place the Sysmac Studio online to the Controller or the Communica-
tions 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, Communications Coupler Unit, or Communi-
cation Control 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 er-
rors in each Unit.
Unit Number of simultaneous errors
System Units When these Units are connected to the CPU Unit, since current
errors are managed in the CPU Unit, the number of current er-
rors is limited by the number of errors for the CPU Units.
For Slave T
erminals, since current errors are managed in the
Communications Coupler Unit, the number of current errors is
limited by the number of errors for the Communications Coupler
Unit.
When these Units are connected to the Communication Control
Unit, since current errors are managed in the Communication
Control Unit, the number of current errors is limited by the num-
ber of errors for the Communication Control 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.
