Connecting the PG to Several Nodes
Stationary PG
1. Use bus connectors to connect a stationary PG in the MPI subnet to the other
nodes of the MPI subnet.
The figure below shows the interconnection of two networked S7-300s
interconnected with bus connectors.

PG for commissioning or maintenance
1. Use a stub cable to connect the commissioning and maintenance PG to the
other subnet nodes. The bus connector of these nodes must be equipped with a
PG socket.
The figure below shows the interconnection of two networked S7-300 and a PG.
