The various kinds of data are stored in the offset positions shown in the following
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)

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.)
