6. Basic Network Configuration
6.1 General Information
The Anybus Communicator offers two modes of operation regarding the network settings:
Settings specified by Configuration Switches
If the on-board switches are set to a non-zero value, the ABC is locked to the following settings:
IP Address:192.168.0.x(x = switch value)
Gateway:255.255.255.0
Subnet:255.255.255.0
DHCP:OFF

Settings specified in Anybus Configuration Manager
When valid settings have been specified in Anybus Configuration Manager
(‘TCP/IP Settings’ = enabled), then these are the settings the gateway will use.
When settings have been specified in Anybus Configuration Manager, the contents of the system
file ‘ethcfg.cfg’ will be ignored completely, causing the following behavior:
- DNS services will not be available
- Domain and Host name cannot be set
- E-mail services will not be available
- Network settings received via HICP or DCP) will be lost in the event of a power loss or a
reset.
Settings specified in ‘ethcfg.cfg’
If no settings are specified in Anybus Configuration Manager (i.e. ‘TCP/IP Settings’ = disabled),
the gateway will use the settings stored in the system file ‘ethcfg.cfg’.
If this file is missing, the gateway will attempt to retrieve the settings via DHCP or HICP for 30
seconds. If no configuration has been received within this period, the gateway will halt and indi-
cate an error on the on-board LEDs.
EtherNet/IP
The TCP/IP settings can be accessed from EtherNet/IP through the TCP/IP Interface Object.

DHCP/BootP
The Anybus Communicator can retrieve the TCP/IP settings from a DHCP or BootP server. If no
DHCP server is found, the gateway will default to the current settings in ‘\ethcfg.cfg’.
If no current settings are available (‘ethcfg.cfg’ is missing, or contains invalid settings), the gateway will
halt and indicate an error on the on-board status LEDs (the network configuration may however still be
accessed via HICP, see “Anybus IPconfig (HICP)” on page 41.
