Activating the SBT can have different sources:
Digital input (non-safe): any digital input on X4 can be mapped to the SBT request.
PROFIbus: the SBT request can be set with telegram 701
Fieldbus: The variable SBT Request (UPID 1A61), see table above.

Safety Fn State
STO
1A10h
Bool
-
STO active
Set if the STO safety function is active and torque/force is removed from the
drive. The activation may be a result from a demand of the Safety
Application Process of a fault reaction from a fault in the safety fault buffer
or a demand from the PROFIdrive on PROFIsafe Safety Function State
Machines.
Cleared if the STO safety function is inactive and torque/force may be
generated from the drive.
This bit can also be accessed via UPID 1A06h bit 0.
STO Selected
1A1Ah
Bool
-
STO selected
The safety module has detected a request for STO, this can also be an
internal event.
This bit can also be accessed via UPID 1A06h bit 10.
Safety Fn State
Error
1A1Dh
Bool
-
Error active
This flag is set if an error on the safety module is active.
Cleared if no error is active.
This bit can also be accessed via UPID 1A06h bit 13.
Safety Fn State Int
Event
1A1Eh
Bool
-
Acknowledge is
required
Set if an explicit acknowledge is required as an interface event.
Cleared if no acknowledge is required.
This bit can also be accessed via UPID 1A06h bit 14
Safety Fn State
Brake Released
1A20h
Bool
-
Brake is
released
Set if the brake is actively driven and should be released (not braking).
Cleared if the brake is not driven and should be braking.
This bit can also be accessed via UPID 1A06h bit 16.
STO active
S_ZSW1
Bool
-
STO active
In case of PROFIsafe S_ZSW1 bit 0 signalizes if STO is active.
