Routing Configuration
The Example of DH-485 Routing Configuration figure below shows an
example DH-485 routing configuration. All node numbers on DH-485 are
given in decimal. Node numbers on ControlNet and slot numbers in
ControlLogix chassis are given in decimal. Links IDs for all networks are given
in decimal.
Example of DH-485 Routing Configuration
IMPORTANT
Some devices in this figure have the same node number
because they are on different networks. Devices on the
same network must have unique node numbers. You must
assign the node numbers.
