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.
Deterministic signal processing in real time is important in industrial networks. PROFINET IO
satisfies these requirements.
International standard IEC 61158 ensures open, multi-vendor systems
PROFINET IO is optimized for high-speed, time-critical data communication at field level.
Within the context of Totally Integrated Automation (TIA), PROFINET IO is the systematic
development of the following systems:
● PROFIBUS DP, the established fieldbus,
● Industrial Ethernet, the communications bus for the cell level.
Experience gained from both systems was integrated into PROFINET IO. As an Ethernet-
based automation standard defined by PROFIBUS International (PROFIBUS user
organization), PROFINET IO is a manufacturer-independent 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 parameterization and diagnostic processes. A PROFINET IO
system is configured in virtually the same way as 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 can consist of
several modules and submodules.
● An IO Supervisor is an engineering tool, typically based on a PC, with which the individual
IO devices (drive unit) are parameterized and diagnosed.
IO devices: Drive units with PROFINET interface
● SINAMICS G130 with CU320-2 DP and inserted CBE20
● SINAMICS G130 with CU320-2 PN
With SINAMICS G130 and CBE20 or with CU320-2 PN, communication via PROFINET IO
with RT is possible.
