6.5 Communication via PROFINET
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 the following communication systems:
PROFIBUS DP
The established field bus
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.
SINAMICS G120 with CU240S PN is an IO device in the sense of PROFINET. With CU240S
PN, communications is established via PROFINET IO with RT.
Note
PROFINET for drive technology is standardized and described in the following document:
