Abbreviations and Terms
Table 3: Abbreviations and Terms used in this Manual
Abbreviation/
Term
Explanation
Description
ALCR
Alarm CR
Acyclic PROFINET IO real-time channel for transmission of
alarm messages.
API
Application
Process Identifier
Addressing level in addition to the slots and subslots. This
addressing level allows you to handle different applications
individually to prevent overlap of data storage areas (slots and
subslots) and concurrent access.
AR
Application
Relationship
Application relationship between IOC or IOS and IOD.
CAT5
Category 5
Cable category 5 according to EIA/TIA-568.
CCx
Communication
channels for
parameterization
Communication channels according to TCI-conformance
classes:
CC1: Conformance Class 1 via
local configuration interface
CC2: Conformance Class 2 via
TCP/IP using Service-Port 6626
CC3: Conformance Class 1 via
PROFINET IO supervisor connection
CPD
Configuration,
Parameterization
and Diagnostic
Configuration, parameterization and diagnostic (CPD) tools
simplify navigation and communication with fail-safe
PROFIsafe I/O modules for setting individual safety-related
parameters.
CR
Communication
Relationship
Communication relationship between IOC or IOS and IOD.
DAP
Device Access
Point (DAP)
Station proxy, network access point, a DAP represents the
fieldbus interface and determines the essential properties of
the IO device.
DCP
Discovery and
basic
Configuration
Protocol
PROFINET protocol used to set station names, IP settings and
other parameters.
DIP
Dual in Line
Package
The DIP switch is comprised of a series of eight individual
shift switches.
GSD
General Station
Description
Device description for configuring IO devices within the
engineering system.
GSDML
General Station
Description
Markup
Language
An XML-based language, GSDML is used as the language for
the device description file.
HTTP
HyperText
Transmission
Protocol
Data exchange protocol used for transmission of internet data,
e.g. transfer of websites. Web browsers communicate to web
servers via this protocol.
IOC
IO Controller
Master in the PROFINET IO network.
IOCR
Input/Output CR Describes the connection for the PROFINET IO real-time
channel in the input and output direction.
IOD
IO Device
Slave in the PROFINET IO network
(here the fieldbus node or station, sometimes also used for the
fieldbus coupler as a station proxy à “DAP”).
IOS
IO Supervisor
Programming device in the PROFINET IO network.
IOX
IO station
Station in the PROFINET IO network, “X” stands for
“Device”, “Controller” or “Supervisor”.
