From simple stand-alone to complex safety applications:
With SIRIUS 3RK3 Modular Safety System (MSS), you can
rely on an integrated safety solution to facilitate machine
and plant operation with maximum flexibility and efficiency for new concepts and retrofits.
The modular design of the MSS with the Basic, Advanced
and ASIsafe central modules offers genuine added value:
You benefit from maximum flexibility within your
applications as well as from cost savings since only the
needed modules are actually employed. The MSS central
module represents the core of a functioning safety chain.
All required safety functions can be rapidly and easily
parameterized via the MSS ES Software using the drag
and drop function. The modular safety system is certified
in accordance with IEC 62061 and EN ISO 13849-1.

Baustein
Application
An agitator is operated at very high speed in
a mixing plant tank. The effective assurance
of personnel protection in all operating modes
necessitates a simple protective door interlocking
solution. This can be accomplished via a speed
monitor or directly by the MSS. This function
can be easily implemented with the Advanced or
ASIsafe central module. These central modules are
comprised of prefabricated blocks with all required
functions relevant for this application. This saves
time in terms of parameterization.
Highlights:
Simple solution for protective door interlocking
Easy parameterization via intuitively operable
MSS ES Software with graphical interface
Optional access for persons according to degree
of authorization

Function block for muting – also for AS-i
Application
An industrial robot stacks the filled boxes on
pallets in a palletizer. The open access point
is protected via a non-contact light curtain. An
additional muting function facilitates the pallets’
smooth removal. The detection and evaluation of
the optical safety mechanism, as well as the additional muting sensors are controlled by the MSS. If
a person accesses the protective zone, the hazard
is detected and the machine is safely switched off
or decelerated, depending on its parameterization.
Highlights:
Increased productivity through higher throughput rates
Easy parameterization based on prefabricated
and certified muting blocks in the MSS ES

Exchange of diagnostics data with the control – also via AS-i
Application
With autonomous safety systems, diagnostics
connection to the supervisory control level is
essential. Diagnostics and control data can be
exchanged via bus, which facilitates the display
of messages on an HMI panel or the transfer
of signals from the PLC to the MSS, both via
PROFIBUS DP as well as via AS-Interface.
Device diagnostics via PROFIBUS:
Reference number: 40631654
Highlights:
Easy visualization through cyclic and acyclic
exchange of control and diagnostics data
Fast and easy connection through prefabricated
function blocks for all S7 controllers
Support of standard or individual messages
through freely connectable signals
High plant availability through high
transparency regarding the plant state

Rapid parameterization of direct data exchange – for easy commissioning
Application
To ensure smooth workflows, the independent
safety cells “box filling” and “palletizer” have to
be connected in terms of safety technology. This
can be easily accomplished through safe direct
data exchange via AS-i. As a result, both standard
as well as fail-safe data can be exchanged between
both cells. Moreover, diagnostics data can be
transferred to the control via AS-i – for increased
plant availability.
Highlights:
AS-i direct data exchange is a simple expansion
option with additional safety cells and their
interlinking with the existing plant
Additional sensors and actuators can be easily
integrated via AS-i without wiring expenditures
Short response times through local signal
processing

MSS ES parameterization software –
comprehensive functionality in one program
Selection and article numbers
Central modules
The MSS ES parameterization software serves as an essential part of our modular safety system. It facilitates rapid
and easy parameterization and does away with the laborious wiring of individual functions.
Simple, fast and efficient
All safety and logic functions are available as ready-touse blocks which can easily be interlinked. All function
elements can be positioned using drag & drop.
One key highlight, the MSS ES supports the safety
application’s testing by means of forcing. With this
feature, outputs can be set in a targeted manner and the
downstream safety function’s response can be monitored
in advance – i.e. without any physically connected sensors
or actuators. This ensures the safety application’s simple
and accelerated commissioning.
Diagnostics
As reliable diagnostics tool, our parameterization software
supports the online condition monitoring of each element
as well as of the entire interconnection.
Documentation
Furthermore, in compliance with DIN EN ISO 7200,
comprehensive documentation of the safety functions is
available.
In addition to the functional scope of the “Standard”
version, the extended MSS ES Premium software
package comprises the following features:
• Parameterization download via PROFIBUS
• Online diagnostics via PROFIBUS
MSS ASIsafe
• Generation, import and export of macros
• Compilation of a library with separate functional units
Advantages at a glance
• Rapid parameterization:
The MSS ES comprises all elements and tools
required for the configuration, diagnostics and
commissioning of your safety functions and
application.
• Easy interlinking:
The MSS ES provides all functions as blocks
which can be easily interlinked with a mouse-click.
