7-1 Overview of Errors
You manage all of the errors that occur on the NJ/NX-series Controller as events. The same
methods are used for all events. This allows you to see what errors have occurred and find
corrections for them with the same methods for the entire range of errors that is managed (i.e.,
CPU Unit, EtherCAT slaves,* and CJ-series Units).
* Only Sysmac devices are supported.
Error management range for NJ/NX-series Controller
You can use the troubleshooting functions of Sysmac Studio or the troubleshooter on an HMI to
quickly check for errors that have occurred and find corrections for them. This manual describes
the errors that originate in the DB Connection Service. Refer to the NJ/NX-series
Troubleshooting Manual (Cat. No. W503) for specific corrections when errors occur and for
troubleshooting information on the entire NJ/NX-series Controller. For information on errors that
occur when DB Connection Instructions are executed, refer to Appendix DB Connection
Instructions.
