Glossary
PG LINK
Serial interface on a CPU, CP/IP module and coordination module (PG-MUX).
Used to connect a programming device. Some CPUs are optionally equipped with
two PG links.
Pixel
Pix Element (picture point). The pixel represents the smallest element that can be
reproduced on-screen or on a printer.
PLC
SIMATIC S5 programmable logic controller
Plug and Play
Generally, a reference to the ability of a computer to automatically configure the
system for communication with peripheral devices (for example monitors, modems
or printers). The user can plug in a peripheral and "play" it at once without
manually configuring the system. The Plug and Play PC requires both a BIOS that
supports Plug and Play and a corresponding expansion card.
PROFIBUS
Bus system based on the PROFIBUS standard. Components of the SIMATIC S5
and S7 series (programming devices, programmable logic controllers,
programmable control systems, distributed I/Os) can be networked using
PROFIBUS.
Programmable Logic Controller System
The programmable logic controllers (PLC) of the SIMATIC S5 system consist of
one or more CPUs and various I/O modules. The PLCs of the SIMATIC S7 system
(for example, S7-200, S7-300, S7-400) consist of one or more CPUs and various
I/O modules.
Programmable Controller (AS)
This programmable controller (PLC) consists of the central unit, a CPU and of
diverse I/O modules.
