PROFIBUS International
Technical committee that defines and further develops the PROFIBUS and PROFINET
standard.
Also known as the PROFIBUS User Organization (PNO).

PROFIBUS node
See Node
A PROFIBUS node has at least one or more ports.
A PROFIBUS node cannot take part directly in PROFINET communication, but must be
implemented by means of PROFIBUS master with PROFINET port or Industrial
Ethernet/PROFIBUS link (IE/PB Link) with proxy functionality.
PROFINET
See PROFIBUS International
Within the framework of Totally Integrated Automation (TIA), PROFINET is the consistent
further development of:
• PROFIBUS DP, the established fieldbus and
• Industrial Ethernet, the communication bus for the cell level.
The experience gained from both systems was and is being integrated in PROFINET.
PROFINET as an Ethernet-based automation standard from PROFIBUS International
(previously PROFIBUS Users Organization) defines a vendor-independent communication,
automation, and engineering model.

PROFINET CBA
Within the framework of PROFINET, PROFINET CBA is an automation concept for the
implementation of applications with distributed intelligence.
PROFINET CBA lets you create distributed automation solutions, based on default
components and partial solutions. This concept satisfies demands for a higher degree of
modularity in the field of mechanical and systems engineering by extensive distribution of
intelligent processes.
Component based Automation allows you to use complete technological modules as
standardized components in large systems.
PROFINET CBA is implemented by:
• the PROFINET standard for programmable controllers and
• the SIMATIC iMAP engineering tool.
The components are also created in an engineering tool that can differ from vendor to
vendor. Components of SIMATIC devices are generated, for example, with STEP 7.
The following figures illustrate how automation solutions are being transformed as a result of
PROFINET CBA.
