Control possibilities

The following options for controlling Safety Integrated functions are available:

Basic Functions
Extended Functions
Note
PROFIsafe or TM54F
Using a Control Unit, control is possible either via PROFIsafe or TM54F. Mixed operation is
not permissible.
The safety-related input and output terminals (F-DI and F-DO) act as an interface between
the SINAMICS Safety Integrated functionality and the process.
A dual-channel signal applied to an F-DI (Fail-safe Digital Input, safety-oriented digital input
= safe input terminal pair) controls the active monitoring of the activation/deactivation of
safety functions.
An F-DO (Fail-safe Digital Output, safety-oriented digital output = safe output terminal pair)
delivers a dual channel signal representing feedback from the safety functions.
Dual-channel processing of I/O signals
A dual-channel structure is realized for data input/output and for processing fail-safe I/O
signals. All requests and feedback signals for fail-safe functions should be entered or picked
off using both channels.
