Configuration - Network List
The Network List tells the local RTU how to communicate with remote RTUs.
By default, an RTU will automatically create or update links in its network list if a message is received that is
new or is different to an existing link. Eg. if an RTU has a network link to RTU2 using port 2 and a message
is received from RTU2 on port 3, the network link will be updated to port 3. This feature can be disabled
using ladder logic (by setting #YMODE.2=1)
An RTU can have direct and indirect links to remote RTUs. For the example below, RTU1 has a direct
communication link to RTU2 and RTU2 has a direct communication link to RTU1 and to RTU3. RTU1 can
communicate indirectly with RTU3.
