Note
The PING command can be executed from the host computer to send an
echo request packet to an Ethernet Unit. The method for using the PING com-
mand from a UNIX computer is given next.
Input the following at the host computer prompt ($):
$ ping IP_address(host_name)
The destination is specified by its IP address or host name. If the host name is
used, the host name must be defined in file /etc/hosts.
The PING command is not supported by some host computers.
These examples show sending the PING command to the node at IP address
130.25.36.8. The “$” in the example represents the host computer prompt.
User inputs are underlined. Comments are placed after semicolons.

Refer to operating system documentation for your host computer for details
about using the host computer’s PING command.
The specifications for these Ethernet Units (CS1W-ETN21 and CJ1W-ETN21)
are compatible with those for previous models (CS1W-ETN01/ETN11 and
CJ1W-ETN11), so previous models being used with existing equipment can
be easily replaced by the new models. Many of the specifications for the new
Ethernet Units have been expanded, however, so there will be a number of
limitations if the Unit is simply replaced.
In particular, the CPU Bus Unit System Setup Area is formatted for the previ-
ous models, so there is no way to make the settings for the expanded specifi-
cations.
To remove these limitations, it is necessary to change the CPU Bus Unit Sys-
tem Setup format from “ETN11 mode” to “ETN21 mode.” Refer to Changing
the CPU Bus Unit System Setup Area Format below for instructions on how to
make the change.
