Overview

SINAMICS
S120 can be scaled with respect to performance and
technology. In the case of more exacting technological require-
ments, for example, the SINAMICS S120 Control Unit can be
replaced by a drive-based controller for motion control. This is
the SINUMERIK 840D sl for machine tools, or the SIMOTION D
for production machinery and plant engineering. It is also easy
to couple the SINAMICS S120 to a higher-level SIMATIC S7 with
integral technology functions.
Scalable motion control functions
Totally Integrated Automation – the unique automation
platform
With Totally Integrated Automation (TIA), Siemens is the only
single-source provider to offer an integrated spectrum of prod-
ucts and systems for all industries. Tailored to meet individual
customer requirements, industry-specific automation solutions
can be implemented efficiently on the basis of TIA. Lower life-
cycle costs for plant operation and a significant reduction in time
to market result in a marked improvement in productivity and
greater investment security.
Easy – Totally Integrated Automation with SINAMICS S120
Apart from SIMATIC, SIMOTION and SINUMERIK, SINAMICS is
also one of the core components of TIA. The STARTER commis-
sioning tool is therefore an integral element of the TIA platform.
It is thus possible to parameterize, program and commission all
components in the automation system using a standardized
engineering platform and without any gaps. The system-wide
data management functions ensure consistent data and simplify
archiving of the entire plant project.
PROFINET – for enhanced performance and
open IT communication
PROFINET, the standard fieldbus of the TIA system, is supported
by all SINAMICS S120 variants. This Ethernet-based bus
enables control data to be exchanged at high speed via
PROFINET IO with IRT or RT and makes SINAMICS S120 a
suitable choice for integration in top-performance multi-axis
applications.
At the same time, PROFINET also uses standard IT mechanisms
(TCP/IP) to transport information, e.g. operating and diagnostic
data, to higher-level systems. A SINAMICS S120 with this inter-
face can thus easily be integrated into factory IT networks.
PROFIBUS
SINAMICS S120 supports PROFIBUS DP. It provides a high-
performance, system-wide communication network which links
all automation components: HMI, controls, drives and I/O
devices.
