4 Installation

4.1 Hardware

The S7/MPI-USB is plugged directly into the PLC. Via the USB cable of the module can be connected to the
PLC as follows:

Normal installation (for programming)

The MPI cable will be connected to the S7 PLC via the 9 pin connector (short side of the cable). The USB
connector on the long side of the cable will be connected with the computer.

S7/MPI-USB as HMI (Human Machine Interface) – adapter

The HMI – function provides the possibility to connect a operator panel (which has instead of a MPI
interface a USB device and understands the HMI protocol) with a S7 PLC (300/400). Connect the cable
between the terminal and the PLC. The HMI – protocol must be part of the operator panel.

There must be a serial communication with the operator panel if this op is new/used at the first time.
Therefore connect your operator panel with the serial COM interface of your computer. After the
communication has been running successfully the panel is ready to be connected to the PLC.

4.2 Software

To communicate with the PLC, please install following products for MPI-USB, S7-USB, MPI-II[only USB], MPI­LAN and S7-LAN:

Connect your module as described in the chapter “ Hardware installation ” to the PLC and to the
programming device or to your computer.

If you want to respond to a PLC via the module you have to comply the requirements as described in the
chapter “system requirements” . In addition,please make sure that the module is properly connected

6.1 Using the PLC-VCOM

(The PLC-VCOM is only needed if your module is not connected via the 9 pin COM port to the computer. For
products with USB, Ethernet connection, etc., the PLC-VCOM is required)

1. Start the PLC - VCOM application (If it has not already started yet).

2. Click in the main window of the PLC-VCOM, in the status area “configure”. The configuration wizard will
start.

3. It lists all the found modules / cables and the additional information’s such as IP address and MAC
address of the module.

4. Choose the desired MPI cable and click „OK“ to go on.

5. If the connection is established the chosen cable is shown in the section state and on the left side you
can see the status connected.

6. It also displays, the PLC-VCOM the IP address for the module and the IP address of the computer which
is connected to the module.

If you have any problems with the use of PLC-VCOM software, go to the chapter PLC – VCOM and look there
for operating instructions.
