General information about PROFINET IO

General information
PROFINET IO is an open Industrial EtherNet standard for a wide range of production and
process automation applications. PROFINET IO is based on Industrial EtherNet and
observes TCP/IP and IT standards.
Signal processing in real time and determinism is important in industrial networks.
PROFINET IO satisfies these requirements.
The following standards ensure open, multi-vendor systems:
● International standard IEC 61158
PROFINET IO is optimized for high-speed, time-critical data communication at field level.
PROFINET IO
Within the context of Totally Integrated Automation (TIA), PROFINET is the systematic
development of the following systems:
● PROFIBUS DP, the established fieldbus,
and
● Industrial EtherNet, the communication bus for the cell level
Experiences from both systems have been and are being integrated in PROFINET. As an
EtherNet-based automation standard defined by PROFIBUS International (PROFIBUS user
organization), PROFINET IO is a non-proprietary communication and engineering model.
PROFINET IO defines every aspect of the data exchange between IO controllers (devices
with so-called "master functionality") and the IO devices (those with so-called "slave
functionality") as well as parameter assignment and diagnostic processes. An IO system is
configured by virtually the same method used for PROFIBUS.
A PROFINET IO system is made up of the following devices:
● The IO controller controls automation tasks.
● An IO device is controlled and monitored by an IO controller. An IO device consists of
several modules and submodules.
● IO supervisor is an engineering tool typically based on a PC that is used to parameterize
and diagnose individual IO devices (drive units).
When a CBE20 Communication Board is inserted, SINAMICS DCP becomes an IO device in
terms of PROFINET. SINAMICS DCP and CBE20 can be used for communication via
PROFINET IO with RT.
