Configuration software

Configuration software updates the device configuration when modules are fitted.

This is done either by copying the configuration files supplied with the device of by

manual configuration.

Device configuration

The device configuration of a SIMATIC PC contains details about its features and

options such as memory capacity, drive types, monitor, network address, etc. The

data are stored in a configuration file and are used by the operating system to

select the correct drivers and device parameters.

When the basic configuration changes, the user can modify the settings using a

program that configures the system (SETUP).

Drivers

Program parts of the operating system. They convert the data of applications into

specific formats required by the peripheral devices (for example, hard disks,

monitors, printers).

Ethernet port

For connecting a local area network (bus structure) for text and data

communications at a data transfer rate of 100 Mbaud.

Expanded memory

Expansion memory modules can be installed to expand the default working

memory of a SIMATIC PC.

Interface module

Module for connecting hardware I/O.

Interface, multipoint

The multipoint interface (MPI) is the SIMATIC PC interface to the SIMATIC S7/M7.

This enables programmable modules, (module, programmable), text displays and

operator panels to be reached from a central point. The nodes on the MPI can

communicate with each other.
