6.3.5 Setting the multicast configuration
Several scanners ("Listen only" or "Input only" connections) can access multicast telegrams which
are sent by drives. Settings for multicast configuration have to be carried out as well in the
EtherNet/IP configuration software (z. B. »RSLogix 5000« from Rockwell).
By default, the Communication Unit automatically generates the multicast IP start address used for
the I/O data transfer. The TTL default value for multicast transmission is ’1’, so the multicast I/O
data packets are exclusively propagated via the local network.
The following multicast codes are configurable:
Multicast IP Start Address
Multicast IP start addresses serve to send a message to the members of a certain group (i.e. possibly
to several nodes).
The multicast IP start address is set/changed in
C13006 .
The currently used multicast IP address of the drive is displayed in C13016/1...4 .

Note!
You can also explicitly set the multicast IP start address and the multicast TTL value. We
recommend, however, not to change the default settings in order to ensure a secure
multicast transmission.
Code Description
C13018 Selection for multicast IP addressing via instance attribute 9 (Mcast Config) in the TCP/IP
Interface Object (245 / 0xF5) ( 126)
• Value ’0’: The default algorithm is used.
• Value ’1’: The address from code C13006 is used as multicast IP start address.
C13019 Setting of the multicast TTL value for the validity time of data packets in the EtherNet/IP
network
(Instance attribute 8 (TTL Value) in the TCP/IP Interface Object (245 / 0xF5) ( 126) )
C13020 Used to set how many multicast IP addresses will be assigned.
(Instance attribute 9 (Num Mcast) in the TCP/IP Interface Object (245 / 0xF5) ( 126) )
Example: Display of the multicast IP address 239.64.2.224
Code
C13016/1 C13016/2 C13016/3 C13016/4
