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:
