PROFIBUS International
Technical committee dedicated to the definition and development of the PROFIBUS and
PROFINET standard.
Also known as the PROFIBUS User Organization membership corporation (PNO.)

PROFINET
Within the framework of Totally Integrated Automation (TIA), PROFINET represents a
consistent enhancement of:
PROFIBUS DP, the established field bus, and
● Industrial Ethernet, the communications bus for the 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 has been part of the standard IEC 61158
since 2003.

PROFINET components
A PROFINET component encompasses the entire data of the hardware configuration, the
parameters of the modules, and the corresponding user program. The PROFINET
component is comprised of:
● Technological function
● Device
PROFINET IO
Within the framework of PROFINET, PROFINET IO represents a communication concept for
the implementation of modular, distributed applications.
PROFINET IO allows you to create automation solutions, which are familiar to you from
PROFIBUS.
PROFINET IO is implemented by the PROFINET standard for automation devices on the
one hand, and on the other hand by the engineering tool STEP 7. In other words, you have
the same application view in STEP 7, regardless of whether you configure PROFINET or
PROFIBUS devices. Programming your user program is essentially the same for PROFINET
IO and PROFIBUS DP if you use the extended blocks and system status lists for PROFINET
IO.

The (optional) technological (software) function includes the interface to other PROFINET
components in the form of configurable inputs and outputs.
The device is the representation of the physical automation device or field device
including the IO devices, sensors, actuators, mechanics, and device firmware.
