PCI
Peripheral Component Interconnect
Bus standard for connecting peripherals to the chipset of a processor
PCIe
PCI Express
Connectivity standard for PC components (replacement for PCI, AGP). Based on individual
serial lanes, each with two differential data lines per transfer direction, which can transfer
gross 2.5 GBit/s full duplex at 1.25 GHz frequency and with DDR transmission; due to 8-bit-
10-bit encoding and longer data blocks, a net of about 250 MBytes/s can be used in both
directions simultaneously. (similar to InfiniBand).
If supported under the auspices of the PCI Special Interest Group (PCI SIG).
Initially the following lane bundles are defined:
PCIe x1: 1 lane, 250 MBytes/s per direction
PCIe x4: 4 lanes, 1 GByte/s per direction
PCIe x8: 8 lanes, 2 GByte/s per direction
PCIe x16: 16 lanes, 4 GByte/s per direction
PCIe x16 is also referred to as PCI Express for Graphics (PEG); graphics cards in x16 slots
may use up to 75 watts power. Cards with x1 interface must run in larger slots, but not vice
versa. Compatibility between other bundle sizes is not defined, but possible and
recommended. Slots may offer less lanes than their size suggests (example: PCIe x16 slot
with only 4 or 8 lanes).
PCIe is also provided for internally linking chipset components. Bridges connect other buses
(PCI-X, PCI).

Programmable Logic Controller
POU
Program Organisation Unit
TDP
"Thermal Design Power"
refers to the thermalpower loss of a processor or other electronic components, on the basis of
which cooling is designed.
Riser card
Riser cards are angled pieces that make it possible to install expansion cards parallel to the
motherboard instead of vertical.
RTOS
Real Time Operating System
SATA
Serial ATA = Hard drive interface for personal computers.
Serial ATA behaves fully compatible with Parallel ATA with respect to BIOS and drivers.
Unlike Parallel ATA, SATA is not a bus with masters and slaves, but a point-to-point
connection. With its transmission speed of 150 MBytes/s, the Serial ATA specification V1.0
(short SATA I) is seamlessly equivalent to the fastest parallel ATA hard drives with 133
MBytes/s; SATA II specifies data transfer rates of 300MBytes/s and SATA III 600 MBytes/s.
SLC / MLC Flash
Single-level cell flash are memory cells consisting of NAND flash, in which each memory cell
stores one bit.
Multi-level cell flash are memory cells consisting of NAND flash, in which each memory cell,
which is composed of a MOSFET and a capacitor, stores a plurality of bits (currently three).

SERCOS over EtherCAT®

Programmable Logic Controller
SSD
A Solid State Drive (also known as Solid State Disk), is a memory medium, that is installed
and accessed like a conventional hard drive, but does not contain a rotating disk or other
moving parts because it comprises only semiconductor memory chips (usually flash) of
similar capacity.
TCP/IP
TCP/IP - Transmission Control Protocol / Internet Protocol
is a family of network protocols.
The network subscribers are identified by means of IP addresses.
Data reception is acknowledged.
UEFI
(Unified Extensible Firmware Interface) UEFI replaces BIOS, but the task to be performed by
UEFI has not changed compared to BIOS: It provides the interface between the hardware
and the operating system, but offers a number of innovations and advantages compared to
