Publication 1756-UM514B-EN-P - February 2003
2-16 Using the Data Highway Plus Network
Example DH+ Routing
Configuration
The figure below shows an example DH+ routing configuration.
Node numbers on DH+ are given in octal. Node numbers on
ControlNet and slot numbers in ControlLogix chassis are given in
decimal. Links IDs for all networks are given in decimal.
Figure 2.5
IMPORTANT
Some devices in the 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.
