2.1 Determine the Best Method for Setting the IP Address
There are three methods for setting the IP address on an NX2A4E2. Table T2.1 below outlines the available
methods and when you can use them.
Table T2.1 Methods for Setting the IP Address
There is a MAC address label on each NX2A4E2 which has a writable surface. There is room
on the label for writing the programmed IP address of the unit. It is a best practice to use this
label to document the IP address of the unit in case it is ever repurposed.
In order to conform to the ODVA specification for EtherNet/IP, the NX2A4E2 also supports
the DHCP protocol. You will need an EtherNet/IP DHCP server, such as the one available
from Rockwell Automation, in order to use this protocol. It is supported, but AMCI encour-
ages you to use the embedded web server if your company policy prevents you from installing
third-party software, such as the AMCI NET Configurator.
2.2a Use Factory Default Settings
The factory default address for the NX2A4E2 is 192.168.0.50 with a subnet mask of 255.255.255.0. The eas-
iest way to verify this address is with the ping command as described in
Configuring Network Interfaces
which starts on page 29.
If the unit does not respond to this address then it may take some effort to determine the correct address.
There is a label on the driver that lists the MAC address of the device. There is space on the label for noting
the IP address of the device if it is changed. If the address was not documented, a program called Wireshark
(
https://www.wireshark.org/ ) can be used to determine the address of the unit.
Task Complete
This section is intended for the engineer or technician responsible for setting the
IP address of an AMCI NX2A4E2.
Method Restrictions Section
Use Factory Default
Settings
1) The machine must use 192.168.0.xxx subnet.
2) The 192.168.0.50 address must be available.
2.2a
Use DIP Switches 1) The machine must use 192.168.0.xxx subnet. 2.2b
Use the Embedded
Web Server
No restrictions on use. This is the preferred method.
The internal webserver can be used to set the
NX2A4E2 to any IPv4 address. The IP address and
protocol will be stored in nonvolatile memory and
used on subsequent power-ups.
2.2c
Use the AMCI NET
Configurator Utility
No restrictions on use. The software can be used to
set the NX2A4E2 to any IPv4 address. The IP
address and protocol choice will be stored in non-
volatile memory and used on subsequent power-ups.
The software utility can also be used to program the
NX2A4E2 and monitor data from it.
