Ethernet Lines

Section titled “Ethernet Lines”

The nX1 has two Ethernet lines: eth0 (EtherCAT local bus via ET1100) and eth1 (standard Ethernet).

Default settings — ETH1:

IP=192.168.1.100  Mask=255.255.255.0  Gateway=192.168.1.1

To modify eth1 settings, connect via SSH (username: root, no password) and edit:

Static IP:

/etc/systemd/network/20-wired.network
[Match]
Name=eth1


[Network]
Address=192.168.1.100/24
Gateway=192.168.1.1
DNS=192.168.1.1

DHCP:

/etc/systemd/network/20-wired.network
[Match]
Name=eth1


[Network]
DHCP=yes

IO Modules

Section titled “IO Modules”

The nX1 provides a local EtherCAT bus via the ET1100 controller, allowing expansion with dedicated I/O modules. XML device files must be imported into the CODESYS Device Repository.

Step 1 — Add EtherCAT Master:

Add EtherCAT master

Right-click the nX1 device in the CODESYS tree and select Add Device, then add an EtherCAT Master or EtherCAT Master SoftMotion.

Step 2 — Select eth0 as network interface:

Select eth0 interface

Step 3 — Add the UFG-FIELDBUS interface:

Add fieldbus interface

Right-click the EtherCAT Master and select Add Device to add the UFG-FIELDBUS interface.
