Internode Test Remote Network Address and Node Number (CPU Unit to Ethernet Unit)
Internode Test Number of Send Bytes (CPU Unit to Ethernet Unit)
The various kinds of data are stored in the offset positions shown in the fol-
lowing diagram, from the beginning word in the area for each Unit.
The beginning word m is calculated by the following equation:
Beginning word m = D30000 + (100 x unit number)

Note For CS-series Ethernet Units, this area is the IP Address Display Area and
data in this area can be transferred from the Ethernet Unit to the CPU Unit
only. For CJ-series Ethernet Units, this area is the IP Address Display/Setting
Area and data in this area can be transferred in either direction.
The meanings of the items shown in the above diagram are explained on the
following pages. For details regarding the related communications services
shown in the diagram, refer to the indicated sections.

m Remote network address
Specify the remote network address and node number in hexadecimal within
the following ranges:
Remote network address: 00 to 7F Hex (0 to 127 decimal)
Remote node number: 01 to 7E Hex (0 to 126 decimal)
If a remote network address is set to 00, it will specify the local network (i.e.,
the network to which the Ethernet Unit is connected.)
