Conditions Requiring Routing Tables
Section 6-7
With Routing Tables
Specify the addresses as shown in the following example.
6-7-3
Using a non-PLC Component as the Target
Network-to-Serial Conversion
Routing tables to enable the serial communications path to be treated as a
network are optional.
Without Routing Tables
Specify the addresses as shown in the following example.
Serial Communications Unit/Board
E.g., Unit number 0, port 1
