Safety Fn State SOS 1A12h
Bool
-
SOS active
Set if the SOS safety function is active. 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 SOS safety function is inactive.
This bit can also be accessed via UPID 1A06h bit 2.
Safety Error State

Enum8
-
This variable shows the error state of the safety functions.
The variable is described in detail in
7.7.2.3- Safety Error State
Safety Error Code
1A03h
Enum8
-
In case of an error, the error code is shown here.
The error codes are described in detail in
7.7.2.4- Safety Error Codes
SOS Selected
1A1Bh
Bool
-
SOS selected
The safety module has detected a request for SOS, this can also be an
internal event.
This bit can also be accessed via UPID 1A06h bit 11.
Safety Fn State
Error
