Topologies

Introduction
The HMI device and PLC can communicate using a PtP connection or within a network.
The HMI device can communicate only with one S7-200 at a time.
4.4.1.1

Communication via a point-to-point connection

In a PtP connection, the HMI device is the only device which is connected directly with the
S7-200. You need an MPI cable or a PROFIBUS bus cable with two PROFIBUS bus
connection plugs to connect the HMI device to the PLC.
