CPU Bus Unit System Setup
To operate the Ethernet Unit as a node on an Ethernet network, the required
parameters must be set in the CPU Bus Unit System Setup, part of the CPU
Unit’s Parameter Areas. If any of the following items apply, then the system
parameters must be set.
• Either the IP address table or both the IP address table and automatic
address generation are used as the destination IP address conversion
method.
• Transmissions are broadcast using a host number set to all zeroes as the
broadcast address (when UNIX 4.2BSD specifications are used for the
broadcast address).
• The FINS UDP port number is set to a value other than 9600.
• With CJ-series Ethernet Units, the local IP address is set with the allo-
cated words in the DM Area.
• A subnet mask other than the one determined from the IP address is set.
• A login name other than CONFIDENTIAL is used for the FTP server func-
tion.
• Communications between segments are required.
• The mail function is used.
Newly set parameters go into effect after the Ethernet Unit has been restarted
or after the CPU Unit is started again.
The settings are made using the Unit settings on the CX-Programmer.
Note The CPU Bus Unit System Setup is located in the CPU Unit’s Parameter Area,
and not in I/O Memory; parameters cannot be written using instructions or by
editing I/O Memory. The settings can be made only using the CX-Program-
