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 465L. 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 465L 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 465L 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 465L, enabling them to communicate.

Verifying Network Hardware Connection
With the 465L 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.”
