Using the V2 or V3 Screen
Use the V2 screen for configuring entries 1 ... 32 for the selected port.
Use the V3 screen for configuring entries 33 ... 64 for this port.
You can alternate between the V2 and V3 screens using commands V2
and V3.
The Table Entry column is a listing of locations in the table. Note that
these are table entry locations, not Modbus addresses. You must enter
the Modbus addresses that you want to map into the second column.
When you edit the table entries, you do not have to do so in a defined
sequence. For example, you do not have to configure E1 before
configuring another entry.
You do not have to fill all the table entries in the V2 screen before
making an entry in the V3 screen. If you will use no more than 32
entries, you might find it convenient to keep them all on one screen.
Example
To use the V2 screen table entry E1 to map Modbus address 20 to the
routing path 21 22 23 24 25, you would enter the following string:
E1 20 21 22 23 24 25
You may find it convenient to use a Modbus addressing convention that
helps you to remember how addresses are mapped in your application.
For example, you can use the Modbus address 124 to define mapping to a
Modbus Plus node address 4, with routing through a Bridge Plus at
address 20. In the same convention, Modbus address 126 would map to
Modbus Plus node 6 through the same bridge. Examples are shown in
table entries E4 and E6.
To map the addresses shown at E4 and E6, you would enter the
following strings:
E4 124 20 4 0 0 0
E6 126 20 6 0 0 0
