Enabling Of The Control Via Profisafe - Siemens Sinamics S120 Function Manual

5.3.1

Enabling of the control via PROFIsafe

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 or F device) with a fail-safe communication to the F host via PROFIBUS or
PROFINET and is assigned its own PROFIsafe telegram.
In this case, a PROFIsafe channel, known as a safety slot, is created using the STARTER
commissioning tool and transferred to HW Config (alternatively, this safety slot can be
created by the SIMATIC Manager Step 7 using HW Config). The Safety Integrated functions
can then be additionally controlled via the PROFIsafe telegrams 30, 31, 901 and 902. The
structure of the associated control and status words is described below (see Section
"Telegram format (Page 177)"). The selected PROFIsafe telegrams for Safety Integrated are
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:
● Basic Functions: p9601 = 8 hex or 9 hex
● Extended Functions: p9601 = C hex or D hex

Lic ense requirement for S afety Integrated functions via PROFIsafe
No license is required to use Basic Functions. This also applies for 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 telegram configuration is
performed in the hardware configuration in the F-host (see Sections "PROFIsafe via
PROFIBUS (Page 312)" and "PROFIsafe via PROFINET (Page 322)").
Safety Integrated Basic Functions via PROFIsafe and via terminals
Control of the Basic Functions via terminals on the Control Unit and on the Motor/Power
Module (parameters p9601.0 = 1) may be enabled in parallel. In order to be able to select
SS1, an SS1 delay time p9652 > 0 must be configured. With PROFIsafe, both SS1 and STO
can be selected. Only SS1 is available for control via terminal.
STO takes priority over SS1, i.e. STO becomes active if SS1 and STO are simultaneously
selected.
