How do I transfer information between PLC to PLC via Modbus Plus ?

You can use either Peer Cop from the Configuration screens, or use the MSTR block.
The MSTR Block can be used to transfer data through a read or write function, or through transfer of global data.
The Peer cop is independant of the MSTR block. The MSTR block is explained in Modfax document #4534 or
the Modicon Ladder Logic Block Library Users Guide , 840USE10100. Peer Cop is expalined in the
Modbus Plus Planning & Installation Guide 890USE10000. Each of these manuals can be found on our web site
