SIRIUS ACT PROFINET
Ethernet for your push buttons, indicator lights and switches
When it comes to communication, SIRIUS ACT is a
strong performer. Besides the standard wiring, you
can also connect these push buttons, indicator lights
and switches directly to the controller –via AS-Interface
or with IO-Link. With our new SIRIUS ACT PROFINET
technology, you can now directly interface to PROFINET
and bring all the features of Ethernet down to the
field level.
Reduced wiring time and effort, minimized error source and
flexibility for future modifications are the main drivers that
push industrial communication systems down towards the
sensors and actuators in the field. SIRIUS ACT PROFINET is
the easy way to connect your push buttons and pilot devices
to the TCP/IP world. Learn how to use PROFINET in your
application in this paper.
Industrial Controls
PROFINET introduction
PROFINET is the open, Ethernet-based communication solution
for the superior control level. With its decisive advantages of
flexibility, efficiency and performance, PROFINET opens up
new ways for you to increase productivity.
Flexibility
Industrial Wireless LAN
PROFINET supports wireless communication with Industrial
Wireless LAN, thus opening up new application fields for
your push buttons and signaling devices. For example,
technology that is susceptible to wear, such as contact
wires, can be replaced. Furthermore, the use of automated
guided vehicle systems and mobile HMI devices becomes
possible. In addition to data exchange with PROFINET,
the IWLAN connection can also be used for additional
communication via standard services such as TCP/IP. Thus,
moving machine parts can be wirelessly integrated in a
plant just like transport systems. The reliability of wireless
communication is essential for this. To ensure that this can
be guaranteed even in harsh industrial environments,
Siemens offers a broad portfolio of wireless components
for a wide variety of applications, including support in
calculating radio fields in the planning phase.
Safety
PROFINET supports the proven PROFIsafe safety profile and
it also allows wireless safety-related communication. The
PROFIsafe profile, which has been tried and tested with
PROFIBUS and which permits the transmission of standard
and safety-related data on a single bus cable, can also be
used with PROFINET. No special network components are
required for fail-safe communication, standard switches
and standard routers can be used without restrictions. In
addition, fail-safe communication is equally possible via
Industrial Wireless LAN (IWLAN).

PROFINET is the open, Ethernet-based communication
solution for the superior control level.
Flexible topologies
PROFINET permits flexible network topologies and optimum
machine and plant planning. PROFINET also enables the use
of star, tree, and ring topologies in addition to the linear
topology characterized by the established fieldbuses. This
results in a high degree of flexibility in the planning of
machines and plants. The PROFINET network can be
installed without specialist knowledge and meets all
requirements relevant to the industrial environment.
Open standard
Due to its openness, PROFINET provides the basis for a
uniform automation network and allows the easy integration
of existing systems. PROFINET, the open vendor-independent
standard (IEC 61158/61784), is supported by PROFIBUS
and PROFINET International (PI). It stands for maximum
transparency, open IT communication, network security
and simultaneous real-time communication. Due to its
openness, PROFINET creates the basis for a uniform
automation network in the plant to which all of the
machines and devices can be connected. The integration
of existing parts of the plant, using PROFIBUS for example,
can also be achieved without any problems through the
use of gateways
Web tools
Since PROFINET supports TCP/IP, it permits the use of standard
web services such as web servers in the field device.
Regardless of the tool used, information from the field level
can be accessed at any time and from nearly anywhere
using a commercially available Internet browser. This
facilitates commissioning and diagnostics considerably.
Users can decide for themselves how much openness to
the IT world they will permit for their machine or plant.
Efficiency
Device / network diagnostics
PROFINET provides an exceptionally powerful means of
diagnosing faults in machines and plants. By retaining the
proven device model of PROFIBUS, the same diagnostics
information is also available on PROFINET. In addition,
Siemens offers useful tools for structuring machine and
plant architecture, suitable for each project phase.
Easy cabling
In industrial environments, high demands are placed on
the installation of the cabling. In addition, industrial-grade
networks must also be set up without special knowledge,
without errors, in the shortest possible time. Siemens
offers FastConnect, a system that meets all these demands.
The time spent for connecting the terminal devices is
minimized thanks to the easy installation using only a
single tool. Furthermore, installation errors are avoided
by a practical color coding. Both copper cables and glass
fiber-optic cables can be assembled on-site in this way.
3
Fast device replacement
PROFINET devices are identified via a name that is assigned
in the configuration. When replacing a defective device, a
new device can be recognized by the IO controller by means
of topology information and have a name automatically
assigned to it. An engineering tool is therefore not required
when replacing devices. This mechanism can also be used
during the initial commissioning of a complete plant. Quick
commissioning is possible for series of machines.
Ruggedness / stability
An automation network must be able to withstand most
external sources of interference. The use of switched
Ethernet prevents faults in one section of the network from
influencing the entire plant network. PROFINET enables
the use of fiber-optic cables especially for areas that are
critically sensitive to EMI.
Performance
Speed
Fast motion control applications need precise and
deterministic data exchange. This is implemented thanks
to isochronous drive controls using Isochronous Real-Time
(IRT). With IRT and isochronous mode, PROFINET supports
high-speed, deterministic communication in which the
different cycles of a system (input, network, CPU processing
and output) are synchronized, even with TCP/IP communication
operating in parallel. PROFINET’s short cycle times make it
possible to increase the productivity of machines and plants,
and to ensure product quality through high precision.
High precision
PROFINET stands for maximum precision with significantly
increased performance – not only in communication, but
integrated in the entire system thanks to isochronous
mode. Machines with several axes are a challenge and are
becoming increasingly important. To increase throughput,
it is necessary to integrate more drives in a machine. At the
same time, these must always work in perfect coordination
with each other. PROFINET with IRT provides the basis for
fast and precisely synchronized communication for motion
control systems.
Large quantity structures
Previous limitations in the scope of the machines and
systems to be implemented can be easily overcome through
the use of PROFINET. With PROFINET, up to 256 field devices
can now be managed by one SIMATIC controller. In a
network, several controllers can interact with their assigned
field devices. Mechanisms such as I-Device allow the simple
set up of hierarchical controller structures. The number of
field devices per PROFINET network is practically unlimited,
the entire band of IP addresses is available.
4
High transmission rate
By using Ethernet in full duplex mode, PROFINET achieves
a significantly higher transmission rate than previous
fieldbuses. Thanks to this, both the process data and other
plant data can be transferred via TCP/IP without any problems.
PROFINET easily comes up to industrial requirements such
as simultaneous transmission of fast IO data and large
volumes of data for other parts of the application. Due to
PROFINET mechanisms, even the transfer of large volumes
of data that are common for video-data does not compromise
speed and precision of IO data transfer.
Media redundancy
Higher plant availability can be achieved by means of a
redundant installation (ring topology). The media redundancy
can be implemented both with the help of external switches
and direct via integral PROFINET interfaces. Reconfiguration
times of 200 ms can be achieved with the Media Redundancy
Protocol (MRP). In the case of an interruption to the
communication in only one part of the ring installation,
this means that a plant standstill is prevented and the
necessary servicing and repair work can be carried out
without time pressure.
Fast start-up
The Fast Start-Up function allows rapid start-up of PROFINET
devices that are connected to SIMATIC controllers. The
communication connection between the controller and the
device is established in less than a second. Thus, in modular
plants, individual parts of the plant can be coupled and
decoupled in minimal time.
PROFINET for SIRIUS ACT
The new SIRIUS ACT PROFINET system brings the features
of PROFINET to your pilot device applications. The system
consists of a gateway that is assembled to the standard
holder of the SIRIUS ACT line, and one safe slot connected
to 20 standard slots via a flat cable.
The standard SIRIUS ACT actuators can easily be snapped
onto the SIRIUS ACT PROFINET slots without the need of
addressing and without the need for any special tools. As
a result the system can be assembled quickly and actuators
can be replaced easily.
How to assemble?
21 slots
Device test without PLC is no problem
The SIRIUS ACT PROFINET devices can be tested without PLC
or software knowledge. Just push the button on the front
side of the device slot and a LED on the backside indicates
if everything is assembled correctly.

Siemens Offers You the Right Solution for
Your Application
AS-Interface, IO-Link and PROFINET coexist in the Totally
Integrated Automation (TIA) world of Siemens. Depending
on your application, you can select and combine the
communication system according to your individual needs.
For applications with a low information volume per device,
for example, digital sensors and actuators such as push
buttons and a medium or high number of network
participants in the switching cabinet or in the field, the
AS-Interface bus system is the system of choice.
Applications that require higher information volume per
device for small quantities, for example, SIRIUS ACT ID
key-operated switch in the switching cabinet or in the field,
the point-to-point connection system IO-Link suits the best.
(diagnostics, parameterization, identification)
