9-1 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,
*1
and
CJ-series Units).
*1 Only Sysmac devices are supported.
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.
Refer to the NJ/NX-series Troubleshooting Manual (Cat. No. W503-E1-19 or later) for error types and
details, specific corrections when errors occur, and troubleshooting information on the entire NJ/NX-
series Controllers.
