Ethernet Configuration
Ethernet is commonly used for factory automation busses with a computer or PLC acting
as a master. The communications protocol used for the Ethernet configuration is
MODBUS TCP/IP. For details on the MODBUS TCP/IP specification, please see
http://www.modbus.org/.
A Windows software application, DeviceInstaller, is available for configuring the
Ethernet module used in the 465M. This application is available for download here:

Hardware Setup for Configuring the Ethernet
Module
To make the first-time configuration of the Ethernet module as easy as possible, the
module comes from the factory with DHCP enabled. The 465M can simply be plugged
into a network with a DHCP server and an IP Address should be automatically assigned
to, and stored in, the device.
A simple network can easily be constructed for this purpose by using a small broadband
router commonly used for home networks. The 465M and a PC can then be connected to
the router and the router's DHCP server will assign IP Addresses to both the PC and the
465M, enabling them to communicate.

Verifying Network Hardware Connection
With the 465M connected to a network and powered up, check the status of the two LEDs
on the Ethernet connector on the rear panel. The left-hand LED should be lit, either
amber or green indicating link status and the right-hand led should blink periodically,
indicating activity on the network. See Table 8-5 below for more details on the status
LED's.
If neither of the LED's are lit, then the Ethernet module may not be powered up or the
instrument may not be connected to a valid network. Check the COM port configuration
per Section 8.2 and make sure that it is set to "Ethernet."
