Master point-to-point messaging
In this type of messaging, the master sends one dataset (LocalDsNr) from its own
dataset table to the follower’s. TargetNode stands for the node address of the
follower; RemoteDsNr specifies the target dataset number.
The follower responds by returning the contents of the next dataset. The response is
stored into dataset LocalDsNr+1 in the master.
Note: Master point-to-point messaging is only supported at the master because the
response is always sent to node address 0 (the master).
Read remote messaging
The master can read a dataset (RemoteDsNr) from a follower specified by
TargetNode. The follower returns the contents of the requested dataset to the
master. The response is stored at dataset LocalDsNr in the master.
Note: Read remote messaging is only supported at the master because the
response is always sent to node address 0 (the master).
