Connecting Peripherals - Siemens SIMATIC HMI SICALIS PMC 7 Equipment Manual

Prerequisites
For the operator panel to support communication with the PLC, you must first
retrofit the PROFIBUS Interface Module, IM 182. This module is not a standard
part of the operator panel package. With the IM 182 interface module, you can
connect the operator panel as a standard slave on a PROFIBUS-DP network. You
must also install the associated driver software.
You will also need the IM 182 interface module for the internal communication
between the operator panel and SIMATIC WinAC.

Connecting Peripherals

Front Panel: MPI Connection
On the front of the operator panel, there is an MPI connection (X14, see page B-1)
for commissioning and service purposes. With this connector, you can temporarily
connect e.g. a programming device without needing to open the cabinet.
The MPI jack is protected by a hinged plastic cover, which guarantees that the
front panel satisfies the requirements of the IP65 safety standard.
Prerequisites for usage:
The MPI connection on the front of the operator panel is wired 1:1 with the 9-pin
Sub-D connector on the back of operator panel (Pos. 3 in the table on page 3-6).
This must be connected to the PLC to enable use of the MPI connection on the
front.
Enabling switch
You can connect an enabling switch to the 17-pin front connector (X13, see
page B-2). The signal lines are fed to the terminal strip on the back of the operator
panel.
An enabling switch ist a hand operated remote control, with which you can operate
the operator panel e.g. when working in the hazardous areas on machines and in
plants.
Note
When connecting devices to the 17-pin connector on the front, their cables must
be shielded and these shields must be electrically connected to the plug.
