In multicast, controllers can be grouped as shown in the example of Figure
3-1.
In this configuration, controllers 1, 2, 4, and 5 belong to Group A, and
Controllers 3, 5, and 6 belong to Group B.
Multicast addresses are set as follows:
• Multicast addresses in Group A
• Multicast addresses in Group B
By doing this, the controllers can be grouped by registering them as follows:
• Controllers 1, 2, 4
• Controllers 3, 6
• Controllers 5
The setting above allows messages to be passed to the controllers that belong
to the group simultaneously.
