Glossary
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.
D
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).
E
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.
I
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.
