Chapter 16 Peer-to-peer Communication Overview
In this network topology, only one controller in Token Group 1 is
allowed to exchange data with one controller in Token Group 2. If
Token Group 2 needs data from different controllers in Token Group
1, the “talking” controller in Token Group 1 must collect the data.
In the HH Network Profile II Configuration Topology example on
page 167 , only these links between Token Groups are allowed:
•
A1
↔
A2
•
B1
↔
B2
•
C1
↔
C2
To configure this scenario, the controllers are placed in their
respective token groups.
In the Peer-to-Peer Editor, you create connections between
controllers. For example, all controllers in Token Group 1 can
communicate to each other, but Controller 1 can also communicate to
Controller 5 in Token Group 2.
