2.4. Peer to Peer Configuration Example 2
Figure 13 shows an example configuration for a system using 4 controllers connected together
using one peer to peer network with dual physical network paths, but this time with multicast
data.
In this example, Controller 4 will be the master of network 1 subnet 1. Controller 1 will be the
master of network 1 subnet 2.
• 16 digital points will be sent from controller 3 to controllers 1, 2 & 4 via a multicast
configuration.
• 16 analogue points will be sent from controller 1 to controller 2.
• A separate set of 16 analogue values will be sent from controller 1 to controller 3.
• 16 digital values will be sent from controller 2 to controller 4.
