Follower Point-To-Point Messaging - ABB ACSM1 Firmware Manual

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 D2D_Conf standard function block (see page 268).
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.
