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.
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
Within the framework of Totally Integrated Automation (TIA), PROFINET represents a
consequent enhancement of:
● PROFIBUS DP, the established field bus,
● Industrial Ethernet, the communications bus for the cell level.
Experience gained from both systems was and is being integrated into PROFINET. As an
Ethernet-based automation standard defined by PROFIBUS International (PROFIBUS user
organization), PROFINET is a manufacturer-independent communication and engineering
model.
When a CBE20 Communication Board is inserted, SINAMICS S150 becomes an IO device
in terms of PROFINET. SINAMICS S150 and CBE20 can be used for communication via
PROFINET IO with RT.
Note
PROFINET for drive technology is standardized and described in the following document:

Real-time (RT) and isochronous real-time (IRT) communication
Real-time communication
If supervisors are involved in communication, this can result in excessively long runtimes for
the production automation system. When communicating time-critical IO user data,
PROFINET therefore uses its own real time channel, rather than TCP/IP.
