10.3.1.1 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,

and

● Industrial Ethernet, the communication 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 is inserted, SINAMICS S120 becomes an IO device in the sense of

PROFINET. With SINAMICS S120 and CBE20, communications can either be established

via PROFINET IO with IRT or via PROFINET IO with RT. Mixed operation is not supported.

Note
PROFINET for drive technology is standardized and described in the following document:
