Controlling the safety functions via PROFIsafe

The safety functions can either be controlled via digital inputs or via the fieldbus i.e.
PROFIBUS or PROFINET with the fail-safe PROFIsafe profile.
Examples for connecting an inverter to a fail-safe SIMATIC control via PROFIsafe is
provided in the Internet under the following URL:
● PROFIBUS control of the safety functions (STO, SLS and SS1) of a SINAMICS G120
● PROFINET control of the safety functions (STO, SLS and SS1) of a SINAMICS G120

Controlling the safety functions via digital inputs

Activating fail-safe inputs
A fail-safe input of the inverter is activated by assigning it a safety function. This is described
in the following using an example. The example shows the assignment of the fail-safe digital
input FDI0 to the STO safety function using STARTER.
Procedure
1. Connect your PC to the inverter e.g. using the PC connection kit.
2. Launch the STARTER parameterization tool and go online.
3. In STARTER, call the screens with the fail-safe functions
