General information about PROFINET IO for SINAMICS

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,
● 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
● IO supervisor is an engineering tool typically based on a PC that is used to parameterize
When a Communication Board CBE20 is inserted, a SINAMICS DC MASTER becomes an
IO device in terms of PROFINET. The SINAMICS DC MASTER and CBE20 can be used for
communication via PROFINET IO with RT.
Cycle communication using PROFINET IO with IRT or using RT is possible on all drive units
equipped with a PROFINET interface. This means that problem-free communication using
other standard protocols is guaranteed within the same network.
