PIC mode
Peripheral interrupt controller. 15 interrupt lines are available.
Pixel
PixElement (picture point). The pixel represents the smallest element that can be reproduced
on-screen or on a printer.
Plug&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. A
Plug&Play PC requires both a BIOS that supports Plug&Play and a Plug&Play expansion
card.
POST
Self-test performed by the BIOS after the computer is switched on. Performs a RAM test and
a graphics controller test, for example. The system outputs audible signals (beep codes) if
the BIOS detects any errors; the relevant message indicating cause of error is output on the
screen.
PROFIBUS/MPI
Process Field Bus (standard bus system for process applications)
PROFINET
PROFINET is the name of the standard for Industrial Ethernet developed and maintained by
the PROFIBUS user organization. PROFINET unites protocols and specifications with which
Industrial Ethernet meets the requirements of industrial automation technology.
Programmable controller (PLC)
The programmable controllers (PLC) of the SIMATIC S5 system consist of a central
controller, one or more CPUs, and various other modules (e.g. I/O modules).
PXE server
A Preboot Execution Environment server is part of a network environment and can provide
software to connected computers even before they boot. This can involve operating system
installations or servicing tools, for example.
