Follower point-to-point messaging
This type of messaging is for point-to-point communication between followers. After
receiving a token from the master, a follower can send one dataset to another
follower with a follower point-to-point message. The target drive is specified using
the node address.
Note:
The data is not sent to the master.
Standard multicast messaging
In standard multicast messaging, one dataset can be sent to a group of drives
having the same standard multicast group address. The target group is defined by
the
standard function block (see page
).
The sending drive can either be the master, or a follower after receiving a token from
the master.
Note:
The master does not receive the sent data even if it is a member of the target
multicast group.
