15-1 Overview of Errors

You manage all of the errors that occur on the NJ/NX-series Controller as 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, NX Units, NX-series Slave Terminals, 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 the Sysmac Studio or the Troubleshooter on an HMI to
quickly check for errors that have occurred and find corrections for them.
To perform troubleshooting from an HMI, connect the HMI to the built-in EtherNet/IP port on the CPU
Unit.
You can also use the Network Configurator to check the network status. Refer to 15-3 Checking Status
with the Network Configurator for the procedure to check network status.
This manual describes the errors that originate in the EtherNet/IP Function Module. Refer to the NJ/NX-
series Troubleshooting Manual (Cat. No. W503) for specific corrections when errors occur and for trou-
bleshooting information on the entire NJ/NX-series Controller.
Precautions for Correct Use Precautions for Correct Use
• CJ-series Units can be used only with an NJ-series CPU Unit.
• The only CPU Unit on which NX Units can be mounted is an NX1P2 CPU Unit.
• Refer to the appendices of the NJ/NX-series Troubleshooting Manual (Cat. No. W503) for the
applicable range of the HMI Troubleshooter.
