3 Basic network configuration
3.1 TCP/IP settings
To participate on the Ethernet network, the EtherNet/IP Module needs a valid TCP/IP
configuration.
The EtherNet/IP Module can retrieve the TCP/IP settings from a DHCP or BootP server. If no
such server is found, the EtherNet/IP Module uses the settings from the system file
\ethcfg.cfg. If this file is not found, or the settings are invalid, the EtherNet/IP Module
will halt and report an error on the status LED. However, the network configuration may
still be accessed via the Ethernet Config Tool.
You can define the TCP/IP settings for the EtherNet/IP Module in the following ways:
• Micro Motion Network Configuration web page (recommended)
• Configuration switches on the device
• Ethernet Config Tool
• System file \ethcfg.cfg on the device
3.1.1
Micro Motion web page for network configuration
The Network Configuration page, in the Micro Motion web pages, allows you to set the IP
address, gateway address, and subnet address. If you connect to the EtherNet/IP Module
using a crossover cable and the default IP address, you can set all three parameters. The
changes will take effect at the next connection.
3.1.2
Configuration switches
If the configuration switches on the EtherNet/IP module are set to any non-zero value, the
device is locked to the following network settings:
Table 3-1: Network settings, locked
Parameter Value
IP address 192.168.0.x where x is determined by the switches
Gateway 192.168.0.255
Subnet 255.255.255.0
DHCP OFF
