Chained multicast messaging
Chained multicasting is supported only for drive-to-drive reference 1 by the firmware.
The message chain is always started by the master. The target group is defined by
parameter
. The message is received by all followers
that have parameter
set to the same value as parameter
in the master.
If a follower has parameters
set to the same value, it becomes a submaster. Immediately after a submaster
receives the multicast message, it sends its own message to the next multicast
group defined by parameter
.
The duration of the entire message chain is approximately 15 microseconds
multiplied by the number of links in the chain (defined by parameter
in the master).
