PROFINET
Within the framework of Totally Integrated Automation (TIA), PROFINET represents a
consequent enhancement of:
• PROFIBUS DP, the proven field bus, and
• Industrial Ethernet, the communication bus at cell level.
Experience gained from both systems was and is being integrated into PROFINET.
PROFINET is an Ethernet-based automation standard of PROFIBUS International
(previously PROFIBUS Users Organization e.V.), and defines a multi-vendor 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.
Component-Based Automation allows you to use complete technological modules as
standardized components in complex systems.
The components are also created in an engineering tool which may differ from vendor to
vendor. Components of SIMATIC devices are created, for example, with STEP 7.
PROFINET Component
A PROFINET component includes the entire data of the hardware configuration, the
parameters of the modules, and the corresponding user program. The PROFINET
component is made up as follows:
• Technological Function
The (optional) technological (software) function includes the interface to other PROFINET
components in the form of interconnectable inputs and outputs.
• Device
The device is the representation of the physical programmable controller or field device
including the I/O, sensors and actuators, mechanical parts, and the device firmware.
PROFINET Device
A PROFINET device always has at least one Industrial Ethernet port. A PROFINET device
can also have a PROFIBUS port as a master with proxy functionality.
