Overview
One concept – 3 platforms
Automation systems are primarily identified by the following
characteristics:
•
System-specific characteristics, e.g. functionality and
engineering
•
Hardware-dependent characteristics, e.g. performance,
design and expandability
However, mechanical engineering demands vary greatly, de-
pending on the version of the machine in question.
Every hardware platform has its benefits when used in certain
applications.
The various platforms can also be combined very easily, which
is a particular advantage in modular machines and plants. This
is because the individual hardware platforms always have the
same system characteristics, i.e. functionality and engineering
are always identical, irrespective of the platform used.
PROFIBUS or PROFINET can be used to create the link to the
drives and the I/Os remotely.
PROFINET/PROFIBUS can also be used for communication with
HMI devices such as SIMATIC HMI or higher-level controllers
such as SIMATIC S7. This means that SIMATIC HMI panels
as well as PCs with WinCC flexible can be used as operator
systems. Even 3rd party applications communicate with
SIMOTION by means of the OPC interface.
SIMOTION D – Compact and integrated in the drive
In SIMOTION D, the SIMOTION functionality is integrated
directly in the closed-loop control module of the SINAMICS
S120
drive system. Therefore, the complete system (consisting of the
open-loop control and the drive) is extremely compact and
powerful.
Two SIMOTION D versions are available:
•
As a SIMOTION D410-2 single-axis system with multi-axis
option (blocksize format)
•
As a SIMOTION D4x5-2 multi-axis system in four performance
variants for up to 128 axes (booksize format)
This finely graded performance ensures the highest degree of
scalability and flexibility. The field of application ranges from
single axes to high-performance multi-axis machines.
For visualization and operation SIMATIC HMI devices can be
connected via PROFINET, Ethernet or PROFIBUS depending on
the SIMOTION D variant. Distributed I/O is connected via
PROFINET or PROFIBUS.
SIMOTION C – Modularity and flexibility
SIMOTION C is a Motion Controller based on the
SIMATIC S7-300 design.
It is available in two variants which differ in terms of their
interfaces, but not with respect to Motion Control functionality or
performance. In addition to the already integrated interfaces,
both controllers can be expanded using I/O modules from the
SIMATIC S7-300 range.
Variant C240 with its four drive and encoder interfaces is ideal
for machine automation applications and the operation of drives
with analog setpoint interface or stepper drives. As a result, this
variant is particularly suitable for machine retrofits.
Variant C240 PN with its three PROFINET ports, which support
PROFINET with IRT as well as TCP/IP and RT communication,
is used to automate machines on the basis of PROFINET. It is
capable of operating PROFINET drives with PROFIdrive, as well
as PROFINET I/Os, such as SIMATIC ET 200S High Speed.
Both variants are equipped additionally with two PROFIBUS
interfaces via which drives with PROFIdrive profile as well as
standard I/Os can be connected. In addition, both controllers
feature an Industrial Ethernet interface, thus offering further
communication options.
