Teledyne 465L Ethernet Configuration, Hardware Setup for Configuring the Ethernet Module

Teledyne API Model 465L O3 Monitor Operation Manual

8.5.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 M465L. 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 M465L 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 M465L 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 M465L, enabling them to communicate.

8.5.2.Verifying Network Hardware Connection

With the M465L 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.”
