If connection type MPI is used for the Push Button Panel, no hardware config-
uration is necessary. Only the MPI address needs to be set on the Push Button
Panel.
Interrelated memory areas must be set up in the PLC for the keys, LEDs and
digital inputs and outputs. The following table indicates the length of the
memory areas to be set up for the various unit versions.

In order to modify system settings, a data block must be created in the PLC
which contains the configuration data for the Push Button Panel. The structure
of this data block parameter is illustrated in Chapter 2.3.1. The number of the
configuring data block must be specified when configuring the Push Button
Panel.
When connection type PROFIBUS-DP is used, the Push Button Panel must be
installed in the PROFIBUS configuration software as a slave in the network. In
the case of SIMATIC S5, the configuration software used is COM-PROFIBUS,
and SIMATIC S7 connection to the network is performed via HW-CONFIG.
The configuration software defines the following:
station address,
separate starting addresses for the I/O areas used,
and the configuration of the buttons and LEDs.
Ensure that the same station address is specified that is set on the Push Button
Panel.
