Setting the multicast configuration
Several scanners ("Listen only" or "Input only" connections) can access multicast telegrams which
are sent by the inverter. Settings for multicast configuration have to be carried out as well in the
EtherNet/IP configuration software (e.g. »RSLogix 5000« from Rockwell).
By default, the Inverter Drive 8400 protec automatically generates the Multicast IP start address for
I/O data transfer. The standard TTL value for Multicast transfer is ’1’; the Multicast I/O data
packages are therefore distributed solely 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
.
The currently used multicast IP address of the inverter is displayed in
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.

Description
Selection for multicast IP addressing via instance attribute 9 (Mcast Config) in the
Interface Object (245 / 0xF5) ( 124)
• Value ’0’: The default algorithm is used.
• Value ’1’: The address from code
is used as multicast IP start address.
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

Used to set how many multicast IP addresses will be assigned.
