In a multicast system, the controllers can be divided into groups as shown in figure 3-5.
Controllers 1, 2, 4, 5 belong to Group A and controllers 3, 5, 6 to Group B.
If Group A is set to the multicast address of 225.224.0.1 and Group B to the multicast
address of 225.224.0.2, the address 225.224.0.1 is registered in controllers 1, 2, and 4
and the address 225.224.0.2 in controllers 3 and 6, while the addresses 225.224.0.1 and
225.224.0.2 are registered in controller 5, thus grouping the controllers as shown. This
permits delivering a message to all the controllers belonging to the group concerned.

Setting with Engineering tool
The Engineering Tool is used for EN7 module setting.
Network Parameter Verification
Set the network to which EN7 modules are connected.
If the IP address type is set to [Setting from Tool], start the Engineering tool and register
network parameters as described below.
For a detailed description of the Engineering tool, refer to its operation manual.
EN7 module engineering is described based on the system configuration shown in figure
3-6.
Figure 3-6 Example of Setting and System Configuration
Check the settings of the following switches before setting the network with the
Engineering tool.
• Check the operation mode switches that they are all in the OFF position.(All OFF in
case of class B)
• Check that the host ID setting switches that the H is set to 1 and the L to 4. (Set to 20
in decimals.)
(1) Then, start the Engineering tool.
