Activation of the integrated safety functions
The integrated safety functions can be activated as follows:
Basic Functions:
•
Over terminals on the SIMOTION D4x5-2 or
CU320-2 Control Unit and on the power unit
•
Over the safety-related digital inputs of the
SIMOTION D410-2 or CU310-2/CU305 Control Unit
•
Over the safety-related digital inputs of the
TM54F Terminal Module
(Note: the TM54F cannot be used on the CU305),
•
Over PROFINET or PROFIBUS with PROFIsafe profile
Extended Functions:
•
Over the safety-related digital inputs of the
TM54F Terminal Module
(Note: the TM54F cannot be used on the CU305),
•
Over the safety-related digital inputs of the
SIMOTION D410-2 or CU310-2/CU305 Control Unit
•
Over PROFINET or PROFIBUS with PROFIsafe profile
•
The SLS and SDI functions can also be parameterized to be
permanently activated.
•
The SBT diagnostic function cannot be activated via safety-
related digital inputs or PROFIsafe, but it can be optionally
activated via the
- Safety Control Channel from the SIMOTION user program
- BiCo signals
- for test stop selection
PROFIsafe
SINAMICS drives support the PROFIsafe profile based on
PROFINET as well as on PROFIBUS.
PROFIsafe is an open communications standard that supports
standard and safety-related communication over the same com-
munication cable (wired or wireless). A second, separate bus
system is therefore not necessary. The telegrams that are sent
are continually monitored to ensure safety-relevant
communication.
Possible errors such as telegrams that have been lost, repeated
or received in the incorrect sequence are avoided. This is done
by consecutively numbering the telegrams in a safety-related
fashion, monitoring their reception within a defined time and
transferring an ID for transmitter and receiver of a telegram.
A CRC (cyclic redundancy check) data security mechanism is
also used.
SIMOTION I-Device F-Proxy
A typical PROFIsafe communication topology between a
SIMATIC safety control and the integrated drives assigned to a
SIMOTION D is shown in the diagram below based on the exam-
ple of PROFINET. This topology is also possible with PROFIBUS
as the basis (PROFIBUS not possible with configuration via
SCOUT TIA).
In this case, the safety control must be configured as a
PROFINET controller or a PROFIBUS master respectively.
SIMOTION D is an I-Device or I-Slave here. SIMOTION D
transfers the PROFIsafe telegrams to the drives via the F-Proxy
mechanism.
Safety Integrated solution based on the example of SIMOTION D4x5-2: Control of the safety functions via PROFINET with PROFIsafe
This topology is also possible if the drives that are assigned to a
SIMOTION D/C/P are connected via a CU3x0-2 Control Unit.
