Checking With The Ethernet/Ip Status Indicators On The Nx-Series Ethernet/Ip Unit - Omron NX Series User Manual

14-3 Checking with the EtherNet/IP Status
Indicators on the NX-series
EtherNet/IP Unit
You can check whether an error related to the communications port of the NX-series EtherNet/IP Unit
occurred or not and the error state with the EtherNet/IP status indicators on the NX-series EtherNet/IP
Unit.
Refer to 3-2-1 Operation Status Indicators on page 3-3 for the location of the EtherNet/IP status indi-
cators.
The error state is checked for each communications port. The following flow diagram shows the proce-
dure for checking the error state for a single communications port.
Refer to the NJ/NX-series Troubleshooting Manual (Cat. No. W503) for details on how to identify the
cause of the error and resetting the error using the Sysmac Studio or an HMI.
In addition, refer to Section 6 Device Variables Related to the NX-series EtherNet/IP Unit on page 6-1
for details on device variables related to the NX-series EtherNet/IP Unit.

used to connect to the Sysmac Studio or an
HMI.

Ethernet switch connected to the
relevant port, replace the Ethernet
cable or the Ethernet switch.
An error for which recovery is not
possible has occurred in Ethernet
communications of the relevant port.

the unit.
An Ethernet communications error

Studio or an HMI to read the device
variable status to isolate the cause of
the error and correct it.
