Fail-safe digital input

This manual describes the STO safety function with control using a fail-safe input. Additional
safety functions, additional fail-safe digital inputs, the fail-safe digital output of the converter
and the control of the safety functions using PROFIsafe are described in the "Safety
Integrated" Function Manual.
Defining a fail-safe digital input
If you use the STO safety function, then you must configure this during the basic
commissioning for a fail-safe digital input, e.g. with p0015 = 2.
The converter combines digital inputs DI 4 and DI 5 to form a fail-safe digital input.
