With CJ-series PCs, words are automatically allocated in the CIO Area and
the DM Area. The Ethernet Unit uses these words for receiving control data
from the CPU Unit and for notifying the CPU Unit of Ethernet Unit and com-
munications status. The word addresses in the allocated areas for the CPU
Bus Unit are important in creating the user program for using the Ethernet
Unit, so be careful to take them into account when setting the unit number.
The following table shows the areas allocated for the CPU Bus Unit by unit
number. This table only shows the correspondences between unit numbers
and the areas allocated for the CPU Bus Unit. For more details, refer to Sec-
tion 4 System Setup and Memory Allocations.

With the FINS communications service, when there are multiple Ethernet
Units connected to the Ethernet network, the Ethernet Units are identified by
node numbers. Use the node number switches to set the node number
between 01 and 7E hexadecimal (1 to 126 decimal). Do not set a number that
has already been set for another node on the same network.

The top switch sets the sixteens digit (most significant digit) and the bottom
switch sets the ones digit (least significant digit). The node number is factory-
set to 01.
