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 465H. This application is available for download here:

8.5.1.
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 465H 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 465H 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
465H, enabling them to communicate.
8.5.2.
Verifying Network Hardware Connection
With the 465H connected to a network and powered up, check the status of the two
LED’s 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.”
