Activation Via Profisafe; Setting Up Profisafe Communication - Siemens SINAMICS S120 Function Manual

Activation via PROFIsafe

As an alternative to controlling Safety Integrated functions via terminals or TM54F, they can
also be controlled via PROFIsafe. PROFIsafe telegram 30 is used for communication using
PROFIBUS and PROFINET.
The structure of the associated control and status words is described further below (see
chapter "Description of telegram 30").
Control possibilities
The following options are available for controlling Safety Integrated Functions:
● Using terminals on the Control Unit and the Motor/Power Modules
● Using PROFIsafe (Telegram 30) via PROFIBUS or PROFINET
● Using PROFIsafe and terminals on the Control Unit and the Motor/Power Modules
● For S120 Cabinet Modules, S150 and G150 also using option K82
6.4.1

Setting up PROFIsafe communication

For PROFIsafe communication, SINAMICS devices require a PROFIBUS or a PROFINET
interface.
Every drive with configured PROFIsafe in the drive unit represents a PROFIsafe slave
(F slave) with a fail-safe communication to the F host via PROFIBUS or PROFINET 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 further below (see Tables "PROFIsafe-STW" and "PROFIsafe-ZSW").
The PROFIsafe telegram 30 is placed in front of the standard telegram for communication
(e.g. telegram 2).
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.
Enabling PROFIsafe
The Safety Integrated Functions are enabled via PROFIsafe using bit 3 of parameters p9601
and p9801:
p9601.3 = p9801.3 = 1
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. HW Config + F-Configuration Pack or SCOUT) on the F host.
