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 Ethenet
Config Tool.
You can define the TCP/IP settings for the EtherNet/IP Module in four ways:
• Micro Motion Network Configuration web page (recommended)
• Configuration switches on the device
• Ethernet Config Tool
• System file \ethcfg.cfg on the device
Micro Motion web page
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.
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:
