under “This Controller” set the “Data Table Address” field to N18:1, set
the “Size in Elements field” to 25, and set the “Channel” field to 1
(Ethernet).
d) Under “Target Device”, set the “Data Table Address” field to N30:50
(starting target address=2050) and set the “MultiHop” field to Yes to
cause the “MultiHop” tab to appear.
e) Under the “MultiHop” tab settings, set the “To Address” in the first row to
the gateway’s IP address, and the “To Address” in the second row to 0.
Refer to Figure 89.
