8.6.5 Control by way of PROFIsafe
Safety Integrated functions
Safety Integrated functions can also be controlled via PROFIsafe, as opposed to control via
terminals. PROFIsafe telegram 30 is used for communication using PROFIBUS or
PROFINET.
Control via PROFIsafe is available for both Safety Integrated Basic Functions and Safety
Integrated Extended Functions.
The structure of the associated control and status words is described in more detail later in
this document (see the "Description of telegram 30" chapter).
8.6.5.1 Enabling of the control via PROFIsafe
SINAMICS devices require a PROFIBUS interface for PROFIsafe communication.
The drive with PROFIsafe configured in the drive unit is a PROFIsafe slave (F slave or F
Device) with failsafe communication to the F host via PROFIBUS and is assigned its own
PROFIsafe telegram.
In so doing, a PROFIsafe safety channel, a so-called safety-slot is created using the HW
Config tool from SIMATIC Manager Step 7. It is then possible to also control the Basic
Functions using PROFIsafe telegram 30. The structure of the associated control and status
words is described in more detail later in this document (see the "PROFIsafe STW" and
"PROFIsafe ZSW" tables). The PROFIsafe telegram 30 is placed in front of the standard
telegram for communication (e.g. telegram 2).
Enabling PROFIsafe
The Safety Integrated functions are enabled via PROFIsafe using parameters p9601 and
p9801:
● Basic Functions: p9601.2 = 0, p9801.2 = 0
Extended Functions: p9601.2 = 1, p9801.2 = 1
● p9601.3 = 1, p9801.3 = 1
Note
Licensing for Safety Integrated Basic Functions via PROFIsafe
No license is required to use Basic Functions. This also applies to control via PROFIsafe.
However, for Extended Functions, you require an appropriate license that will be charged
for.
All parameters involved in PROFIsafe communication are password protected against
undesirable changes and secured using a checksum. The telegrams are configured using a
configuration tool (e.g. SIMATIC Manager HW Config + F-Configuration Pack or SCOUT) on
the F host.
